Since the elastic component is injected directly onto the stable thermoplastic body without prior priming, the associated costs can be effectively saved. In this way, applications in accordance with common food and drinking water requirements (FDA, BfR, etc.) can be guaranteed and demanding specifications of the electrical industry can be fulfilled.
In addition, additional functions are integrated into components through material combinations. Bendable or filigree parts made of rubber become dimensionally stable and can thus be mounted in a functionally reliable manner. This leads to a reduction in the scope of assembly as well as additional reworking and lowers quality assurance costs. A central advantage of rubber-plastic compounds is that, unlike metallic materials, they are not prone to corrosion. Moreover, the total weight is reduced enormously by substituting the metals accordingly.
We offer various material combinations of plastics and elastomers in direct bonding. In addition, an application-related material selection enables function- and cost-optimised solutions.
Pipe clamp made of rubber and plastic: Our modular tube connector system was developed for connecting glass tubes in photobioreactors. The requirements for the rubber-plastic pipe clamp are extensive, because on the one hand the component must resist the existing pressure of the plant and on the other hand it must guarantee a reliable tightness.
The simple assembly and disassembly of the pipe clamp using a torque wrench also eliminates the need for heavy power tools. Furthermore, the tight screw connection of conventional metal clamps often leads to glass breakage, which can be significantly reduced by using the Jäger clamp.
The use of the rubber-plastic pipe clamp in other industries or with pipes made of different materials (glass-plastic or metal-plastic connections) is possible without any problems. They are already used in solar water treatment plants or in the plastics industry for granulate conveying.
Pressure roller for seed drills: Components for the agricultural sector are usually exposed to various environmental influences and strong physical stresses. They must be resistant and should remain serviceable for as long a period as possible. Should individual components fail, this can have serious economic consequences, as the periods during which sowing and harvesting can take place are limited.
Above all, material combinations of rubber and plastic allow reliable and consistent use of the machines, as they provide the necessary robustness despite their low weight and without the risk of corrosion.
Seed drills use pressure rollers to regulate the depth of seed placement and for soil compaction after the sowing process. Previously drawn furrows are closed to prevent the seed from lying open in the field. For this purpose the press rollers must work permanently with appropriate pressure and on different types of subsoils.
The JÄGER Group manufactures assemblies made of high-strength rubber and highly resistant plastic for this purpose in order to withstand the extensive influences such as abrasion and specific force-displacement behaviour. The penetration of dirt into the pressure roller bearing is optimally prevented by a well thought-out construction of lip seals and dust caps.
Suspension elements: Suspension elements manufactured as moulded articles with a firmly adhering connection of rubber and metal are used as components for vibration insulation, shock absorption and noise damping. While the actual spring body is made of rubber, the metal is used for stabilization and fastening.
Compared to insulators made of other materials, mounting elements made of rubber-metal offer the advantage of damping, damping and springing. They are maintenance-free as well as easy and quick to install. In addition to an extensive range of standardized bearing elements which are kept in stock, we are your competent partner for the development of special parts.
We supply suspension elements in the following designs:
For special requirements, however, the use of alternative materials is possible and sensible.
For applications in the upper temperature range, for example, silicone is a suitable material.
Injection molded seal:
In many technical systems, the highest demands are placed on the individual components installed with regard to reliable sealing. In addition, the assembly process of individual components is often difficult, as conventional flat gaskets or profile gaskets cannot be installed due to the lack of space. For this reason, we offer the possibility of vulcanising the seals directly onto metal lids or housings using a tool in the injection moulding process. Thus the gasket is directly connected to the metal component and offers the following advantages, especially compared to freely applied gaskets:
Coating for rollers: In roll coating, metal cores are coated with a rubber layer, thus enabling a combination of both material properties. During production, the unvulcanised rubber is either wound onto the metal core or applied in a compression or injection mould to vulcanise it afterwards. The range is supplemented by roll cover hoses, which are already vulcanized and then wound under pretension onto the metal core.
We also offer covers made of already vulcanized rubber sheets, which are glued to the metal core with special adhesive. In many cases, roller covers are exposed to several stresses at the same time. This is why special experience is required to determine the cover quality, the design of the core and the surface quality. We have decades of experience in this field.
Valve balls: In valves, rubber balls act as a common shut-off device and thus prevent the unwanted backflow of gases, liquids or granular materials and dust. In the cage of the ball valves is the freely movable rubber ball, which is lifted from the valve seat by the inflowing medium. In the event of backflow, the ball is pressed back into the hard valve seat by force and its own weight, thereby sealing it. The valve seat should be adapted to the material used for the valve ball. Another field of application is the area of float balls. Ball concepts with floating elastomers and core materials are used here. For the various specific operating conditions, we have appropriate materials made of elastomers and plastics available.
Screen cleaning balls:
Our rubber balls are used for cleaning industrial screening plants. The balls are added to the material to be screened and their bouncing behaviour causes permanently repeated collisions with other balls, the material to be screened as well as the screen itself. These recurring impulses keep the screen passages clear. In order to counteract the resulting abrasion pressure and to ensure the required bounce characteristics, we use materials that are characterised by low abrasion and good rebound elasticity. This ensures the best possible results during the cleaning process.
Our expertise in the field of balls enables us to produce a wide range of standard dimensions as well as numerous intermediate sizes in various degrees of hardness to meet your specific sealing application.
Advantages of compression packing:
A special material — expanded PTFE (ePTFE): Our strategic partner TEADIT® uses a thermal expansion process following the sintering of the stuffing box packings to minimize the creep behavior of PTFE typical for the material. This results in sealing elements such as tapes or cords with monoaxial alignment or flat gaskets as well as plates with multidirectional structures. A high chemical resistance as well as a very good compressibility characterize ePTFE and predestine this material for sealing plastic and steel joints as well as for enameled flange connections. Furthermore, they often replace plates with hollow glass bead fillers.
Stators consist of a steel jacket lined with rubber. The composition of the rubber compound in the stator depends on the requirements of the progressive cavity pumps and the medium to be pumped.
In materials handling technology, not only the abrasion behaviour but also the given physical, chemical and thermal medium properties are important factors that affect the composition of the material in the stator. The rubber mixture is therefore composed in such a way that the material wear of the stator is kept as low as possible. This increases the service life of your stators and prevents costly failures.
Assembled hose lines: Hoses and fittings are assembled by us into a functional and application-specific complete line. We procure all the necessary connecting and fitting parts, cut the hoses to the exact length and assemble them into ready-to-use systems. According to customer specifications, we can check and document the operating pressure for each hose line individually.
Our range of hoses and fittings extends from simple water hoses to chemical hoses against aggressive media. Among other things we supply hose lines in the following designs:
Spira® stators offer many advantages over conventional stators. In particular, the higher torque for the same stator length, the uniform swelling in aggressive drilling fluid media and the uniform thermal expansion ensure significantly higher efficiency and longer durability. Spira® stators therefore drill to the required depth even in difficult applications without having to be replaced in between, thus saving a lot of time and money. The availability of different elastomers such as NBR, NBR-HR, HNBR and FKM for our stators offers optimal adaptation possibilities for your applications.
Advantages of SPIRA® Stators
Cast iron forms the heart of all drive wheels. Most drive wheels are separable to facilitate assembly and replacement. The wheel halves form matching pairs and must not be mixed. Our drive wheels are supplied drilled and keyed according to your specifications and, depending on requirements, the type and size of the keyways are cut according to German DIN (metric) or customs standards. The friction drive types FR, FRD and KW can be used with any belt type and pitch.
Special driver or cam profiles ensure loss-free transport of goods and can be manufactured by us from vulcanisation or plastic injection moulding tools with narrow tolerances.
With individual surface structures and hole patterns, we open up further, diverse process possibilities.
We optimize your production processes for the following applications, among others:
We offer among others the following materials in the field of belts:
"Silentium Drive"; for more power and comfort during harvesting
Our “Silentium Drive” is based on a rubber fabric belt with parabolic cams, which replaces the conventional steel roller chain. This cam belt is manufactured in two versions: endless wound or with open ends and a special joining method. Bolts are vulcanized into the belt for an optimal connection between steel strips and belt.
A further challenge is the high maintenance requirement of the steel roller chain used up to now. If not re-tensioned regularly, failures can occur and the combine harvester stops. Wear and tear is also problematic, as both the chain and the sprockets must be constantly monitored. If the combine fails during harvesting, the availability of parts and the replacement time are crucial. Every hour that the harvesting machines stand idle causes further costs.
The advantages of Silentium Drive
The “Silentium Drive” also helps to noticeably reduce maintenance costs:
We are particularly proud of our specially developed idlers made of glass fiber reinforced plastic in combination with a rubber compound tread. The plastic has a noticeable effect in the lower weight, the elastomer ensures excellent running smoothness and provides the required elasticity for the idler.
We manufacture the lightweight rollers from these special impact-resistant and wear-free plastics:
The plastic rollers are rubberized, have a low weight and are equipped with two ball bearings type 6005 2RS. They are available as standard with trunnion or open axle.
The cast iron rollers and rubberized rollers are equipped with two ball bearings type 6005 2RS as standard. Depending on the load, some rollers are offered with bearings of type 6206 2RS.
All plastic, cast iron and rubberized rollers have a three-part seal on both sides as standard to prevent contamination:
With our belts and the different pitches of the bar spacing we offer you the best possible influence on the quality of the screened surfaces. Heavy and sharp-edged stones, metals and organic materials can be picked up without any problems.
High-quality products for demanding applications
With our stepped or shafted and then vulcanised endless joints, we achieve release strengths far above the specifications and thus enable high load change stress. Artemis sets standards in the development of endless wound belts in any length as if “from a single mould”.
Our innovative technology opens up further diverse applications for rubber fabric belts in a wide range of applications. These long-life belts replace heavy, noisy and wear-prone steel chains in machines for agriculture, waste management, soil remediation and beach cleaning. They make it easy to increase conveying speeds. The existing nominal strength of the belts can be fully utilised. In addition, compared to conventional splicing technology, a lighter fabric construction with lower strength can be made possible when used with smaller deflection diameters. A high pitch accuracy is achieved by a defined fabric pre-stretch. Even with friction drive with hydraulic pre-stretching, a long service life can be achieved with this system.
Within the JÄGER Group, it is possible to continuously develop the different types of connections through laboratory and test bench tests under simulation of real operating conditions.
Sliding layers made of highly abrasion-resistant material, low-stretch tension member fabric combined with high-quality blends guarantee a high, consistent and excellent product quality. Our innovative joining techniques ensure maximum durability at all times. On request, we can supply the conveyor belts ground ready for installation and perforated for vacuum operation with the latest machine technology with exact tolerances according to customer specifications.
Our JetFlex® product portfolio includes disc diffuser, tube diffuser and strip diffuser, which are suitable for various applications.
We develop the materials of our aerator membranes ourselves: In our in-house laboratory, our chemists test wastewater-resistant materials made of elastomers and polyurethane.
We use the following membrane materials for the aerators:
The disc diffuser and tube diffuser are available with membranes made of EPDM, silicone, PUR, NBR and FKM, optionally with PTFE coatings. Both types of diffuser convince by low maintenance and quick installation. The product range is completed by our strip diffuser made of PVC with a micro-perforated membrane made of PUR. They are characterized by easy installation on the pool floor and a long service life.

JetFlex® HD disc diffuser also offer the following advantages:
Offshore wind turbines in particular are faced with the challenge that the ocean currents erode the soil layer around the foundation. This process is usually counteracted with the backfilling of stones.
However, the challenge cannot always be solved in this way. Sometimes the right rock is not available in the region in question to stop the scouring process.
Jäger Mare Solutions basalt bags are a flexible and environmentally friendly solution. The bags are made of a specially developed basalt fabric and are conveniently filled with round gravel or sand on site. Besides the application as scour protection, our Jäger basalt bags can also be used for the weighting of submarine cables or pipelines and as fixation in dike and coastal construction.
Your advantages of our Jäger basalt bags:
Boatlandings of wind turbines are exposed to particularly high loads — maintenance boats damage the surface coating of the boat landing during docking due to the up and down movement caused by waves.
Hunters Mare Solutions protectors provide a remedy: The hard shells made of basalt fabric and vinyl ester resin are attached to the fender tubes with an adhesive specially manufactured for this application — similar to a shin guard. This can be done both on- and offshore.
Since basalt is a natural product, it is also non-toxic and therefore absolutely future-proof. Hunter’s protectors have to be as well, because even in cold salty sea water and under high UV exposure our protectors have a very long life span due to the basalt fabric.
Your advantages thanks to our JÄGER protectors:
The Big Bubble Curtain
The Big Bubble Curtain is comprised of one or two hoses which are laid out in a ring around the source of noise. The perforated hoses are pressurised with compressed air – bubbles emerge from the sea-bed to the surface of the water which create a ring-shaped protective wall around the noisy construc-tion site. With the help of the bubble curtain the sound waves extensively spreading over the seabed are broken multiple times, decreasing the sound intensity and thus protecting the marine animals. After deployment, the hose system is retrieved and brought to the next construction site.
The Jaeger CBC
Our Conducted Bubble Curtain ensures less noise in the direct vicinity of the ramming point. Jaeger Mare Solutions is currently developing a flexible Conducted Bubble Curtain which is directly attached to the steel rod rammed into the seabed and which creates a dense net of air bubbles. This reduces the noise of the over 1000 required rams directly at the source while ramming the pile into the seabed.
The Jaeger BBC
With our new hose system, which is still under development, we can achieve the same noise mitiga-tion performance with substantially less pressure. For this reason, Jaeger Mare Solutions employs a technology developed for waste water treatment which has been tried and tested for 40 years at Jae-ger Umwelttechnik. With our innovative Big Bubble Curtain, we want to protect the marine animals, encourage the development of renewable energies, and reduce the costs for our customers. This is achieved with an improved bubble performance and the reduction of the required compressors.
How does it work?

Biological wastewater treatment with textile fixed bed
Cleartec® Biotextil is a textile growth carrier for microorganisms and is used for expansion or perfor-mance enhancement in municipal and industrial wastewater treatment plants. It is also used for space-saving biological treatment or pre-treatment of industrial waste water directly in the plant. The high efficiency enables a very compact design when constructing new sewage treatment plants. Cleartec® Biotextil is made of Polypropylen (PP).
Its flexibility, highly structured, large active surface and high resistance to chemicals relevant to wastewater technology make it an excellent material for supporting biological activity in wastewater treatment plants.
Biological wastewater treatment in combined process
The Cleartec® Biotextil system is usually operated in a combined process. This means that both the suspended biomass as in the normal activated sludge process and the so-called sessile biomass fixed on the biotextile contribute to the cleaning performance.
The advantages of Cleartec® Biotextil at a glance:
The Cleartec® module consists of:
1. Stainless steel module
The stainless steel module serves as a supporting structure for Cleartec® Media (Biotextile and BioCurlz). The biotextile panels are fixed in the module by support tubes which are built into fixing loops. Each biotextile sheet has up to four loops, depending on the total material length. BioCurlz are fastened in the module by metal-reinforced support rods.
2. Cleartec® growth media
The textile structure of Cleartec® BioTextile and BioCurlz offers a large surface area and high roughness. It supports ideal conditions for the growth of biofilms. The textile flexibility associated with the air flow generated by diffuser regulates the biofilm thickness and prevents media clogging.
Fine bubble aeration diffuser are installed underneath Cleartec modules and the textiles. The diffuser have two functions to supply microorganisms with oxygen and to create a vertical flow. This vertical flow helps to control the biofilm thickness and contributes to its constant regeneration. It easily removes parts of the old biofilm and provides space for new active microorganisms to attach themselves to the media.

Non-positive drive elements
If the energy in a technical system is transmitted by the frictional forces generated between belts and driving wheels, this is referred to as non-positive drive elements. These are used wherever no synchronous movement of the elements is required and the drive may or should have slip. For this area we offer, among others, V‑belts, V‑ribbed belts and flat belts.
flat belts have a rectangular cross section and, like all non-positive drive elements, transmit energy exclusively via frictional forces. The contact surfaces of the associated drive wheels usually have upwardly curved or raised edges to prevent the belts from slipping off the pulley.
V‑belts are characterized by their easy installation and long service life and allow a high transmission ratio. They are available with sheathed or open-flank design and offer higher transmittable power than flat belts.
V‑ribbed belts have individual ribs which run lengthwise to the belt itself. The larger contact surface on the V‑belt pulley results in greater friction and thus a higher power transmission than with ordinary V‑belts. They are very well suited for the simultaneous drive of auxiliary units.
cushions are in demand from national billiard associations as well as from
renowned table manufacturers. Our profiles can easily be glued to the
billiard table and guarantee precision in the course of the game at
tournaments and thus objectively comparable game results.
Our billiard cushions are — in contrast to many cheaper products — provided with two cotton fabric pads during production and heated in molds. This guarantees a synchronous run over the entire production length.
The materials used, BIBA RED, TBB GREY and KHF GREY, consist mainly of high-quality natural rubber. Additives according to our formula give the rubber mixture its special suitability for the game of billiards and excellent resistance to ageing.
The processing of plates, blocks, tubes, hoses and solid rods is done by hand using mechanical aids. Sophisticated production techniques and qualified personnel guarantee high quality and constant dimensional accuracy. Due to their extensive design possibilities, freehand articles can be used in the most diverse areas. These include general mechanical and plant engineering, pump technology or agricultural technology.
Bends made of rubber are used in systems where the directional flow of gases or liquids is to be diverted. When choosing the right material, rubber offers the advantage over metal manifolds that it can also be used to transport corrosive fluids. In addition, a certain degree of flexibility can be guaranteed with reliable dimensional stability.
Molded rubber parts are elastic, pressure-resistant and abrasion-proof as well as mechanically and chemically resistant. The respective operating conditions and the desired function determine the choice of material and the type of manufacturing process. Each manufacturing process has specific characteristics and must therefore be precisely matched to the order to be produced and the associated purchase quantities. We can map both individual and series production as well as mass production within the JÄGER Group or via our strategic partners.
For the production of rubber molding parts we have, in addition to conventional vulcanization presses in which displacement and transfer molds are used for the compression molding process (CM) and the transfer molding process, injection presses for the injection molding process (IM) of the most modern design. Material, production process and production method are coordinated in such a way that an economic optimum in production and application is achieved. Among other things, the use of cold runner technology contributes to this, which also helps to protect the environment and conserve resources.
Molded rubber parts are subject to the influence of changing media, temperatures and climatic conditions, mechanical stresses or ozone and UV exposure from solar radiation, which limits their useful life and service life. In order to guarantee high quality, we rely on our own material development and production.
For this purpose, we carry out mechanical and dynamic tests, vulcanization and processing tests as well as material and damage analyses in the development laboratories of the JÄGER Group. For further analyses (e.g. electron microscopic examinations) we cooperate closely with the German Institute for Rubber Technology (DIK) in Hanover.
Cushioning mats and panels are usually made of rubber granulate or cellular materials. These are used to decouple machines and systems and are intended to minimize the vibrations generated during production. The damping of vibrations contributes to the protection of the machine environment as well as to a longer service life of the actual plant. It also reduces the maintenance requirements of susceptible components, which can significantly reduce the associated costs.
We supply rubber mats in the following designs:
In the case of dynamically stressed profile seals, we calculate the necessary contact pressure forces and then adjust them specifically by means of hollow chambers or foam structures. The necessary overlap or the gasket stroke can be numerically optimized by means of FEM analysis. These special designs are supplemented by a wide range of standard profiles.
To improve the handling and to facilitate further processing, we offer various finishing options.
Different hose variants
Since both the design and the materials and manufacturing processes used for a hose must always be precisely adapted to the existing conditions of the application, there is no hose that can meet all requirements and loads at the same time. For this reason, we advise you from the very beginning in order to precisely understand the challenges facing the component and to achieve the desired goal together.
Mandrel heated molded hoses
Narrow bending radii and limited installation space require the use of pre-bent shaped hoses produced in the mandrel heating process. Hoses manufactured on mandrel are extruded or wound. These usually have only very narrow dimensional deviations in the inner and outer diameter and are therefore suitable for applications which only allow very narrow tolerances. On customer request we develop hoses of any length and diameter. By means of injection molding, form-bound branches and fittings can be vulcanized on.
We supply rubber hoses in the following designs:
O‑rings made of EPDM and NBR
As with all technical products, there is no universal solution for O‑rings for all applications. The material as well as the dimensions and assembly of the O‑rings must be adapted to the respective overall system and the given influences. If an assembly is exposed to external weather conditions, the material EPDM (ethylene propylene diene rubber) has become established.
Since EPDM is highly resistant to ozone and ageing and also has good resistance to cold temperatures, the material is predestined for such areas. However, EPDM has no resistance to mineral oil-based media and swells strongly under their influence. In this case, NBR (acrylonitrile-butadiene rubber) is the ideal choice, as this rubber is highly resistant to greases and oils based on mineral oil.
We supply O‑rings in the following designs:
Foams are produced with or without pressure, depending on the process. Foaming is achieved by mechanical or physical processing or by a chemical reaction using blowing agents. The selected process and the raw material composition of the materials have a decisive influence on the achievable density of the foams, as they have an open, closed or mixed cell structure after production. The processing can be done by extrusion or injection molding. Prefabricated sheet products are often die-cut.
Common to all foams is the low weight, due to the low density. Parameters such as restoring force, compression set (DVR), water absorption capacity, acoustic decoupling, shock absorption, damping and insulation capacity sometimes differ greatly.
Usually, rubber components are incompressible in a firmly installed state if there is no room for them to escape when force is applied. An exception, however, is in the form of foamed elastomers. Due to the cellular structure of the material, the space required for displacement within the pore structure itself is provided, allowing compression even in fully filled spaces. This property predestines foams for sealing and insulation applications where no other material can offer an alternative.
Processing of flat semi-finished products —
water jet cutting
In contrast to the usual punching process, the manufacturing process of water jet cutting offers the advantage that it is particularly suitable for soft or multi-layer materials. In addition, materials of varying hardness and fine geometries can be processed. Plates lying flat on a metal grid are cut with a precisely directed thin water jet. The large number of different materials and the large differences in the number of stampings and blanks require specific production facilities. We therefore rely on strategic supply partners who complement our in-house production for projects with small quantities and specific manufacturing processes.
Various finishing techniques can be used to significantly extend the possible uses of stamped parts and blanks. To facilitate component handling and reduce assembly work, the following techniques, among others, can be used
While the “Slide-Out System” delivers an outstanding solution to maximize interior RV space, protecting the interior space from the outside elements creates a significant design engineering challenge. The sealing system plays a significant role in creating a watertight interior, minimizing temperature intrusions while delivering durability under dynamic and static loading conditions over a wide range of temperatures.
By working closely with RV manufacturers in rapidly expanding the use of Jaeger Unitek Sealing Solutions Patented Flip ‘N Seal Slide-Out Sealing System®, together, we have met the complex application demands with Slide-Out sealing requirements. The results are a watertight seal, a one-part sealing solution vs. a two-piece design, lower installation costs during seal preparation and installation, and the elimination of reduced warranty claims. For consumers, this translates into the growing use of RV slide-outs to create more interior space, protection from the outdoor elements, satisfaction and enjoyment in the great outdoors.
The advantages of Flip ‘N Seal include:
The decisive factor for a plastic molded part that is convincing in use and withstands the given influences is the correctly selected production process. Within the JÄGER Group as well as through our strategic partners, various projects can be realized with different processes.
Among other things we offer:
The parallel development of plastic molded parts and tooling concepts ensures optimum throughput times and the best possible product performance. The use of simulation software for FEM (Finite Element Method) strength calculations and for displaying the mold-filling behavior (mold-flow) ensures the structural stability of the components and ensures reliable process sequences later in production.
Among other things, this mechanical processing is used to produce rods, profiles or sheets from selected plastics. Since the quality of the semi-finished plastic product has a decisive influence on the properties of the later end product, a correct choice of material must be made in advance. Among other things, resistance to certain media and the existing temperature conditions in use should be taken into account.
Your projects are realized in close cooperation with the respective production departments, so that your requirements are implemented constructively. We will advise you individually and according to your application-specific requirements.
Machining of semi-finished plastic products
We manufacture many types of products from semi-finished products made of thermoplastics and thermosets as well as laminates — by mechanical processing, cutting or non-cutting. The versatile application of plastics results from their excellent mechanical, chemical and electrical properties. In addition, the high strength combined with low weight and the possibility of further processing by bonding, welding or hot forming offers a wide range of applications for our semi-finished products.
Your projects will be realized in close cooperation with the respective production departments, so that your requirements will be implemented constructively. We will advise you individually and according to your application-specific requirements.
Special material requirements:
As with metal alloys, these properties can be supplemented and extended by certain additives. Thermoplastics such as PE or PP, for example, can be significantly mechanically reinforced by adding fillers. Compared to metallic materials, plastics offer the advantage that they are easy to shape, have a low specific weight, can be coloured as desired and are highly resistant to chemicals.
Plastic profiles have a lower strength than metal profiles and a significantly lower heat resistance. For this reason, a precise knowledge of the operating conditions and the desired functions is required in order to be able to select the appropriate material for each profile.
Our plastic profiles are used in the construction industry, in vehicle construction, in various mechanical engineering applications, in plant construction, in the electrical industry, in agricultural engineering and in the wind energy sector, among others. We would be pleased to advise you on the selection of the material and on the functional and plastic design of the profile for your application.
Co-extrusion for special applications
Within the scope of co-extrusion, several different plastics with different properties can be brought together. For this purpose, several extruders are arranged in blocks of two or three so that the melt flows of the respective extruders run parallel and are joined to form a single profile strand. The resulting n‑plex profiles can cover a wide range of requirements. In addition, different colors or hardnesses can be combined.
Fabrication and finishing
The further processing of plastic profiles to finished parts according to drawings is usually carried out by downstream equipment within the production line. After cooling, profiles are drilled, punched or milled in the line. Fasteners, end pieces and caps can also be directly injection moulded onto cut profile pieces after the actual production process. Fastening elements such as clips can be formed by mechanical processing.
Heat shrinkable tubing
Shrink sleeves are used to sheathe sensitive components and thus protect them from environmental influences or various media. They are expanded during the production process directly during extrusion and only cooled down afterwards. As soon as the shrink hose is exposed to heat, it contracts back to its original size and thus reliably encloses the sheathed components. The so-called shrinkage rate (2:1; 3:1; etc.) indicates the ratio of the inner diameter before and after shrinking. Especially PVC tubing or also PTFE tubing is used in the electrical industry to protect cables or other conductors.
The choice of materials
Plastic hoses are made of different types of plastic and accordingly have different properties. Above all, the chemical resistance of the materials as well as their temperature resistance and physical properties are the main focus. However, plastics also differ considerably from an economic point of view, which is why the required conditions should be tailored exactly to the respective application. We advise you from the ground up and find the right hose for every application.
We supply plastic hoses in the following versions:
Protective plugs are used to cover openings and bores or as dust protection for sensitive components. Both products can be manufactured in various plastics as well as in different colors. Due to their simple but at the same time indispensable function, they are used in the entire machine and plant construction as well as in the hydraulic industry.
Due to countless possible applications, protective caps and plugs must have the most diverse geometries. A version without thread is suitable for protecting protruding components (screw heads or nuts), as these can be fitted comparatively easily and removed again if necessary. Plugs without threads can be used for permanent use in drill holes or other openings, but are difficult to remove again. Screw plugs or sealing screws are suitable here. These are screwed or unscrewed directly into or out of the intended opening and thus allow easy removal. A further possibility is provided by so-called strap plugs, which are fastened for quick assembly by simply pressing on them, but can be removed just as easily through the existing strap.
We supply protective plugs and protective caps in the following designs:
