High-quality, thermoformable foam products are often used to manufacture roof linings in the automotive sector. A special stirrer mixhead and extremely powerful axial piston pumps enable outputs of up to 7500 cm³/s – even if there is a great difference in viscosity. This allows large foam blocks of up to 6m³ to be made. The HK-R measures out liquid materials from amply-dimensioned work tanks. A plate heat exchanger replaces the shell and tube heat exchanger in the return line so as to control the temperature. It is installed in a separate, constant temperature control circuit with a dedicated pump that takes up much less space.
          • Mixheads

              • High-pressure mixheads

              • Use [y]our Head.
                Hennecke high-pressure mixheads
                One key factor that ensures the quality and efficient processing of polyurethane is mixhead technology. The development and manufacture of high-pressure mixheads requires a great deal of know-how and experience. Hennecke has decades of expertise and makes its mixheads (apart from a few standard parts) in its own manufacturing halls. This is a novelty in Europe and one reason why many leading PU processors opt for Hennecke’s high-pressure mixheads. They know from experience that it pays off to introduce them into their production lines. No matter if rigid or flexible, integral, filling or energy-absorbing foam is concerned, Hennecke has the appropriate mixhead for almost every application, whether this is standard or specific. Variable sizes and injector shapes as well as a comprehensive range of accessories ensure that the mixheads can be fitted to suit a great variety of imaginable applications – yours too.
                  • MT mixheads

                  • High-efficiency deflection mixheads for very small to very large outputs
                    MT mixheads are the most recent addition to Hennecke's mixhead portfolio, embodying a fundamentally new design which sets new standards in high-pressure polyurethane mixing technology. To the user, this innovation translates first of all into optimum processing results across the entire range of common PU systems. Our MT mixheads can inject up to six reaction components into the mixing chamber via high-efficiency injectors. From there the reaction mix flows into the 90° offset outlet pipe. This deflection supports the mixing process, calms the mixture and ensures a laminar, splash free discharge into the open mould. Due to their robust design, MT mixheads are also particularly maintenance-friendly and noted for their extremely attractive lifecycle costs. Moreover, they are optionally available with Hennecke constant pressure injectors which maintain an almost constant mixing pressure over a wide operating range. Output changes can thus be made without injector adjustment. At the same time, the application range of the mixhead is effectively expanded.
                  • MN mixheads

                  • Groove-controlled linear mixheads for RIM applications, filler processing and spraying
                    Our MN linear mixheads operate on the groove-control principle. Due to their special parameters, they are particularly suitable for polyurethane spray-moulding processes (PUR-CSM technology) and applications involving filled components. Hennecke's lineup of 2- to 4-component MN mixheads covers a vast spectrum of outputs, ranging from 6 cm³/s to 10,000 cm³/s. For CSM spray applications, users can optionally add 'smart' MN accessories such as a spraying lance for complex mould geometries or a high-performance cutter for a metered addition of glass fibres. Moreover, MN mixheads are ideal for attachment and thus suited for all RIM and RRIM processes. MN mixheads are optionally available with Hennecke constant pressure injectors which maintain a virtually constant mixing pressure over a wide operating range. Output changes can thus be effected without injector adjustment. At the same time, the application range of the mixhead is effectively expanded.
                     
                  • MX mixheads

                  • Piston-cleaned mixheads with double deflection
                    Apart from an excellent mixing quality and shot reproducibility, the MX type series allows for a very easy pressure control. The two or three-component mixheads are handheld or available as an add-on option. Typical uses are cold-curing flexible foam, rigid and semi-rigid integral skin foams as well as compact systems and filling foam. MX mixheads are also designed for pentane-blown systems. The double deflection of the flow makes groove-controlled recirculation mixheads particularly suitable for difficult-to-mix raw material systems. Moreover, MX mixheads are optionally available with Hennecke constant pressure injectors which maintain an almost constant mixing pressure over a wide operating range. Output changes can thus be made without injector adjustment. At the same time, the application range of the mixhead is effectively expanded.
                     
                  • MQ mixheads

                  • Piston-cleaned deflection mixheads with integrated component separation
                    For decades, our MQ mixheads have gained a reputation for outstanding robustness and reliability, especially in processing components of low to ultra-low viscosity. Apart from their exceptional mixing quality, the integrated separation of reactive components gives the operator additional safety. Due to their ability to deactivate injectors individually, the 4- and 6-component versions enable a fast "shot-to-shot" selection of the formulation. MQ mixheads are mainly used for TDI systems or TDI blends.
                  • MD mixheads

                  • High-pressure mixheads for continuous sandwich panel applications
                    MD mixheads are operated on the impingement injection principle. Owing to their relatively small design dimensions and low mass, these dynamic mixheads are particularly well suited for use on oscillating filling manipulators. Their adaptability to various discharge systems enables MD mixheads to cover a broad range of applications. In CONTIMAT lines, the discharge system takes the form of a distribution rake to ensure a wide laminar application of perfectly conditioned material to the lower metal facing. Moreover, our MD mixheads are optionally available with Hennecke constant pressure injectors which maintain a virtually constant mixing pressure over a wide operating range. Output changes can thus be made without injector adjustment. At the same time, the application range of the mixhead is effectively expanded.
                  • ML and MXL mixheads

                  • Air-cleaned high-pressure mixheads for various applications
                    Air-cleaned „L-type“ ML and MXL deflection mixheads operate on the proven impingement injection principle. The entire recirculation of the components is groove-controlled. Due to the patented air cleaning capability based on the cyclone principle, the need for using solvents has been eliminated completely. When operated manually, the low weight of the ML and MXL mixheads enables ergonomic and less tiresome work even if moulds are difficult to access. With outputs of up to 9,000 cm³/s, these air-cleaned mixheads are also suitable for demanding tasks such as foam-insulating district heating pipes. Moreover, our ML and MXL mixheads are optionally available with Hennecke constant pressure injectors which maintain an almost constant mixing pressure over a wide operating range. Output changes can thus be made without injector adjustment. At the same time, the application range of the mixhead is effectively expanded.
                • Stirrer mixheads

                • A striking head
                  Low-pressure mixheads made by Hennecke

                  For some raw materials and applications, mixing based on the impingement injection principle is impossible. Casting systems or high-viscosity components are just two cases in point. For many reactive components and additives – e.g., in continuous slabstock lines – mixheads are fitted with special stirrers to ensure that the reactive systems and additives are mixed homogeneously in the mixing chamber and a laminar output is achieved.
                  To a certain extent, processors can influence factors such as the cell structure and cell size of foaming systems by means of particular types of stirrer. High-strength stirrers are used in compact and cellular elastomer systems, ensuring optimal results even when the processing parameters are extremely difficult.
                    • MEL mixheads

                    • Stirrer mixheads for elastomer applications
                      Right from the start, MEL mixheads are equipped with a hydraulic control of the mixhead injectors for extremely short and synchronous switching cycles. This is a novelty that guarantees the processor a superior metering quality. Moreover, MEL mixheads are also fitted with a sophisticated mixing chamber and stirrer geometry in hardened steel so that an excellent mix quality is guaranteed even when raw materials are difficult to mix. MEL mixheads are on offer for six or eight components. They are optionally available with Hennecke constant pressure injectors which maintain a virtually constant mixing pressure over a wide operating range. Output changes can thus be made without injector adjustment.
                    • Stirrer mixhead for slabstock

                    • Dynamic stirrer mixer for slabstock applications
                      Slabstock stirrer mixheads combine injection and stirring principles and guarantee the user a laminar liquid laydown over the entire foaming width. Foam qualities with an extremely uniform pore structure that is free of pinholes and striation are achieved. The actual mixing unit is located centrally in the system’s foaming portal whereas the liquid laydown is discharged onto the bottom conveyor by a funnel that can be adjusted automatically or manually, depending on the system configuration.
                       
                    • Stirrer mixhead for HK-R 5000

                    • Stirrer mixheads for highest quality foams with extreme outputs
                      HK-R stirrer mixheads are applied when extremely high-quality foam products for use in the automotive industry, or rather automotive interiors, are made. The highest amount of mixing energy possible is required to ensure a homogeneous cell structure. That’s why HK-R stirrer mixheads are equipped with a tailor-made mixing chamber and speed-controlled stirrers with a special geometry. Additional features such as adjustable mixing chamber pressure and a control-piston operated system for switching from recirculation to shot enable a laminar and absolutely bubble-free flow.
                  • Slabstock lines

                      • Continuous slabstock lines

                      • Cost-efficient production of high-quality flexible foams
                          • MULTIFLEX

                          • Production lines for the continuous manufacture of high-quality slabstock foams
                            Hennecke is considered the market leader in the field of slabstock machines and systems. This know-how is reflected in MULTIFLEX lines. When it comes to manufacturing slabstock in a continuous process, the use of high-pressure technology, the liquid laydown process and the flat-top system allows processors to achieve a highly efficient raw material yield and excellent foam qualities. As the MULTIFLEX is equipped with high-quality standard components, it can make the most of its advantages at an excellent price-performance ratio while reducing maintenance and spare parts costs. Its modular design is also consistently based on economic principles: Assembly and start-up times are reduced efficiently and for a long time after delivery, the plant can be retrofitted with additional modules, special accessories and equipment to meet new market conditions. This means that the production process will remain competitive in the long term.
                          • QFM

                          • Production lines for the continuous manufacture of high-quality polyether and polyester-based slabstock foams
                            The results of over 60 years of research and development are reflected in Hennecke’s QUADROFOAMAT (QFM) slabstock lines. Thanks to the fact that all components across all viscosity ranges are precisely metered, output settings are exactly reproducible, the adjustment range is large and because the plant has been combined with the extremely successful UBT technology including fall-plates, QFM lines open up many horizons for the efficient production of pinhole-free ether and esther foams that are up to 2,500 mm wide and, depending on the foam type and density, up to 1,500 mm high. A computer-controlled flow metering system provides additional production reliability, in particular when formulations or colours need to be changed on the fly without stopping the plant. Depending on foam type, formulation and plant configuration, cell sizes of 8-100 ppi are possible.
                          • JFLEX

                          • Ultra-compact plants for the continuous production of slabstock foams
                            So far, the market gap lying between discontinuous and continuous slabstock lines has not been covered yet. Hennecke is targeting at foam manufacturers who want to achieve a better quality and higher raw-material yield than with discontinuous plants but are unwilling to make the high investment in conventional continuous lines. With the JFLEX series, Hennecke has now launched a new slabstock line which also offers users with medium production volumes all the advantages of continuous production. The state-of-the-art production system is particularly impressive because of its extremely compact design and its excellent price-performance ratio. Of course, it comes with the usual Hennecke quality to the last detail.
                             
                        • Discontinuous slabstock lines

                              • Discontinuous slabstock lines

                              • Minimal use of space, easy start-up, flexible production

                                When small batches are produced or special foams such as visco-elastic foams are being made, the discontinuous production of flexible slabstock foams is often the most suitable solution. This is also true in terms of economic efficiency. Discontinuous slabstock lines made by Hennecke are very convincing because they require less invest and less space. Of course, the company also has decades of experience in discontinuous lines and only uses tried-and-tested quality components.
                          • LABFOAM

                                • LABFOAM

                                • Slabstock systems technology for test series and laboratory purposes
                                  The use of a LABFOAM laboratory plant quickly pays off - especially if you already produce slabstock products continuously. Even if LABFOAM systems operate discontinuously, their major area of application is about conducting test series for different raw materials and additive systems used in continuous slabstock production. Thanks to high-precision metering pumps, superior mixing technology and modern automisation, different test formulations – as opposed to manual production – can exactly be transposed to real production conditions. Thus you can judge the specific character and quality of a formulation without interrupting your current production or wasting a large amount of valuable raw materials in test series.

                                • Continuous sandwich panel lines/Discontinuous sandwich panel lines

                                • Continuous sandwich panel lines
                                  Continuous production of metal composite elements and insulation panels
                                  The economic superiority of sandwich construction has been noted since the 60s. Nowadays, more than 60 million square metres of roof and facade elements are manufactured and used in Europe each year. In the past five decades, the number of residential buildings that are constructed with sandwich structures has multiplied. The reason for this is simple: Polyurethane rigid foam has the lowest thermal conductivity of all insulating materials and is therefore used in the form of metal composite elements in industrial and cold store construction but also in cooling chambers for supermarkets or in thermal assemblies for trucks. Hennecke was a pioneer from the very beginning, introducing its high-developed, continuously operating sandwich panel lines early on in the success story. High conveyor precision and exact process control are key conditions for ensuring the highest surface quality and optimal characteristics. Apart from classical metal composite elements, Hennecke sandwich panel lines are suitable for manufacturing flexible facings and composite elements with mineral wool.


                                  Discontinuous sandwich panel lines
                                  Discontinuous production of metal composite elements and insulation panels

                                  In many applications, the discontinuous production of sandwich panels with polyurethane core offers decisive advantages and important unique features, for instance, when using facing material with specific properties or incorporating special fixings. Discontinuous panel manufacture also makes sense when small outputs or extraordinary dimensions are required. Of course, precisely controllable production processes and high-quality end products with ideal insulating properties are also ensured when using discontinuous equipment made by Hennecke.

                                    • Systems technology for the discontinuous production of sandwich panels
                                      PANELFOAMER production systems cover a wide range when it comes to the discontinuous manufacture of sandwich elements in terms of dimensions, facing and foam systems. To attain plane-parallel sandwich elements, heavy duty steel hydraulic presses are used. They are equipped with heated plate, rack and pinion guide system and special clamping cylinders. To prepare the reactive PU mix, PANELFOAMER systems use tried-and-tested TOPLINE high-pressure metering as well as mixheads that are either cleaned pneumatically (MXL) or with a piston (MT) and are moved by a special traversing rail system. Thus, big panels can also be foam-filled perfectly easily. The wide range of applications and the reliable systems technology of the PANELFOAMER have been developed in successful cooperation with the UK-based Hennecke agency AutoRIM Ltd.

                                        Every year, over 150,000 tonnes of PU raw materials are processed into moulded foam parts for cars using Hennecke's moulded foam systems technology. Apart from seats, head and backrests, there are many other applications in which the focus is on damping, insulation and the look and feel of a material. Considering the fact that there are more and more models but fewer lot sizes and shorter production cycles, systems that can be used to manufacture different products in all kinds of quantities in an automated and profitable manner are required. Our manufacturing know-how in this field gives you a high degree of investment security. This is also true for special requirements. Apart from oval conveyors and rotary tables, Hennecke can also supply highly specialized TRANSFER, TRANSFLEX, SHUTTLE and POLYSHUTTLE lines.

                                            Flexible oval conveyor systems for varied products and large quantities

                                            Hennecke's WKH oval conveyors use an oval transport system. The main area of application is the production of PU foam parts for car seating and head and backrests. Smaller parts as well as other products from different fields of application can also be made with the flexible WKH systems technology. Because processors are often confronted with the challenge of using different formulations for a whole range of products depending on the manufacturer and type of car and because the number of seating variations is increasing steadily, a mould change is often required. Hennecke’s oval conveyors are appropriate here especially because they have an automated in and outfeed station (QCD or ECD system) which enables the exchange of mould carriers during production and at a conveyor speed of up to 15 m/min.
                                          • Rotary tables (RTN/RTH)

                                          • RTN/RTH systems
                                            Rotary table systems for medium to large production quantities

                                            Hennecke's rotary table systems comprise a circular horizontal conveying unit that accommodates the mould carriers. The technology is suitable for medium to large production volumes. The rotation of the table may be indexed or continuous, depending on process requirements. The cycle length is determined by the moulded part having the longest curing or handling time. Hennecke supplies rotary table systems in diverse circumferences. In line with customer needs, they can be combined with automatic filling manipulators, robots and/or electronic logging of production parameters for quality assurance.

                                              • Stationary production

                                              • Modular systems for manufacturing moulded foam products in small quantities as well as for laboratory use
                                                When moulded foam products are made in a stationary process, the mould carrier stays in a fixed position. When several mould carriers are used, their assembly can be either linear or circular. Stationary moulded foam systems are mainly used when large-sized foaming moulds are involved or lower quantities are to be made, for pre-series or laboratory tests for example. Stationary systems are also ideal for applications with short curing times or different cycles. These latter determine the number of mould carriers used and also the optimum plant size within a series production.

                                                • Carrier systems for moulds
                                                  Hennecke mould carriers from the SM, SV, SVH and SSH series are central components of moulded foam lines. They are stationary or integrated into transport systems and serve to carry the foaming moulds. Mould carriers perform the closing and opening movements, absorb the process-related forces and turn the mould into a position that is ergonomic for users and handling equipment. The differences in the various carrier systems lie mainly in the opening and locking mechanisms.

                                                • Modular systems technology for effectively insulating refrigerator cabinets
                                                  When it comes to foaming lines for refrigerator cabinets, Hennecke is a pioneer of process and systems technology. For example, it has mastered the environmentally compatible insulation of refrigeration appliances by introducing Pentane Process Technology (PPT). Today, Hennecke's refrigerator cabinet foaming lines (KGS) account for a flexible implementation of a large part of the world’s refrigerator cabinet production. Apart from meeting high environmental standards, KGS lines also fulfil the strictest requirements regarding cost effectiveness because raw materials are exploited extremely efficiently and there is a comparatively low use of energy and space. The system's unique modularity allows users a wide spectrum of possible end products – both in terms of quantity and quality. A wide range of products can be made thanks to the flexible application possibilities and specific plant characteristics.

                                                • Systems technology for the automated production of refrigerator doors
                                                  The ROTAMAT polyurethane foaming line is the consistent implementation of the industry's demands on the highly automated, discontinuous production of insulated polyurethane door elements. ROTAMAT lines are mainly used for insulating door elements with rigid PU foam (e.g. in refrigeration equipment or air handling units). Another potential use is the manufacture of insulated polyurethane panels for varied applications. Hennecke's expertise in this field guarantees the user efficient raw material utilization combined with low energy consumption. Moreover, the plant requires much less space than rotary table systems and allows an extremely quick mould change. Thanks to the use of Pentane Process Technology (PPT), the ROTAMAT not only meets economic requirements, but also lives up to the highest ecological standards.

                                                  • Manufacture of lightweight composites with a polyurethane matrix
                                                    The use of fibre-reinforced composites often starts when the properties of conventional materials no longer meet the customer's requirements. For the production of automotive load floors, for instance, lightweight composites with a polyurethane matrix completely meet the mark. The combination of materials allows for the positive characteristics of the individual components to be exploited while cancelling out unwanted features. End products thus benefit from high component strength and stability combined with low weight and complex geometries. With over 40 production lines installed and 90 % market coverage, CSM-Preg manufacturing cells make full use of their unique selling points in this area of application and are known for providing reliable production conditions that are perfectly suited for large volumes. As a generalist, Hennecke can supply everything along the process chain on a turnkey basis and tailored to individual production capacity requirements - from preform, robot technology, press and spray booth to safety technology.

                                                  • Reinforcement of bathtubs and shower trays
                                                    One forward-looking yet eco-friendly major application of PUR-CSM technology lies in the substitution of GFRP mouldings such as bathtubs and shower trays. Here, the use of PUR-CSM meets the most exacting demands in terms of production flexibility, reproducible part quality and material efficiency. For instance, CSM-reinforced bathtubs exhibit an outstanding thermal insulation and clearly reduced sound emissions. Moreover, the full elimination of solvents not only cuts production costs but also simplifies exhaust air system requirements substantially. CSM-Sanitary manufacturing cells are available in several designs and for various production capacities. Each line comes equipped with a TOPLINE high-pressure metering machine (a special version for sanitary applications) and state-of-the-art two-component spray mixheads. Multi-component systems and cutters for glass-fibre reinforcement are available optionally.
                                                     
                                                  • CSM-Sprayskin plant technology

                                                  • Production of PU spray skins for automotive and non-automotive applications
                                                    The benefits of spray technology will pay off especially when it comes to finishing complex parts such as dashboards or door panels. A layer of aliphatic paint is initially applied by In-Mould Coating (IMC). This UV-resistant coating is then reinforced with a sprayed aromatic polyurethane. Compared to PVC, this combination exhibits greatly improved haptic properties and extremely low emission values. As the coating will only be applied where needed, up to 10% material savings can be achieved. Thus, spray skin is not only one of the most top-grade surface technologies, it is also very attractive in terms of cost. In addition, the user will achieve a reduced specific density at the same skin thickness. Hennecke supplies tailor-made systems technology for CSM-Spray-Skin applications. Depending on the design, these lines are fully suitable for large-scale production.
                                                     
                                                  • CSM-Synthetic-Leather plant technology

                                                  • Production of synthetic spray skins in leather look
                                                    In the production of synthetic leather, the focus is on a coat thickness that is as homogeneous as possible - along with an uncompromising look and feel. This requirement has always been of major importance in the manufacture of plastic products in general and within PUR-CSM technology in particular. Moreover, the use of polyurethane is attractive for ecological and economic reasons because the need for solvents has completely been eliminated. CSM manufacturing cells for synthetic leather products combine these high-class product features with a homogeneous continuous spray-coat application. Thanks to this special design, the plant enables a continuous production process. An additional advantage in the production of PU sprayed skins in leather look is that the production colour can be changed within minutes. Thanks to the use of In-Mould-Coatings (IMC), this high degree of product versatility is achieved. As the fundamental systems technology is based on production lines for synthetic leather products where the coating is applied using a scraper, for instance, CSM-Synthetic-Leather technology can easily be retrofitted to many existing production lines and integrated completely.
