APPLICATIONS
AUTOMOTIVE
AUTOMOTIVE
-
It is estimated that more than 20% of world production of plastic is for the automobile industry. In recent years we have witnessed a strong activity in the substitution of metal components in favour of plastic.
BMB is able to tailor our machines suit exactly the finished product, such as bumpers, dash boards, head lights and “under bonnet” components.The introduction of new resins with higher wear resistance and improved thermal and mechanical properties has widened the potential of “under bonnet” thermoplastic products, be they motor components, tans or radiators.
HEAD LAMPS
- In close cooperation with leading companies in the automotive lighting industry, we have developed innovative solutions for machines with 2-3 or 4 injection units and incorporating rotary table technology capable of achieving the highest levels of precision and reliability in the moulding of highly complex light clusters. Paying particular attention to programming in order to simplify the moulding cycle setting procedures and thus reduce the set-up times.
MORE AND MORE COMPLEX COMPONENTS
-
The automotive industry is constantly evolving and constantly demands components that can reduce the final assembly time. Another requirement is to produce components incorporating additional features such as moulded in seals to absorb vibrations and reduce noise levels during the vehicle running and multiple colours or materials to enhance design features.
We have therefore designed systems optimized for every need for example:
• components with different moulded materials or inserts.
• co-injection.
• gas injection.
• rotary tables or ‘core back’ technology
PACKAGING
THIN WALL CONTAINERS
- The packaging industry demands faster, more precise and robust machines.
Over the years cycle times have become ever shorter even with higher cavitation and 24/7 working.
Overlapping movements, thinner wall sections and the consequent reduce cooling time all contributing to cycle time reduction.
DISPOSIBLE CRATES
- Disposible crates have become the most economic solution for the transport of fresh fruit and vegetables with the market demand growing rapidly.
Pressure from the food industry to replace traditional wooden crates with plastic crates that are more hygienic and easy to clean is immense.
The collapsible versions also meet the requirements for space saving transportation and storage.
BMB offers fast cycling machines for both single cavity small crate (550 tonnes press) and 2 cavities larger crates (1300 tonnes press).
PAILS AND ROUND CONTAINERS
- The extended opening strokes inherent in the KW toggle clamping design, allow the production of deep products with a lower tonnage machine.
The increasing application of IML systems also leads to the demand for machines with extended opening strokes to facilitate the insertion of labels and the extraction of the finished product.
PET
PREFORMS
- System for the production of preforms from 8 cavities up to 144 cavities.
CAPS AND CLOSURES
PERFORMANCE AND RELIABILITY
-
Typically, high volumes at low production costs are the pre-requisites in the manufacture of caps and closures.
Therefore, machine performance and reliability are key factors to enable cost effective production.
With a vast amount of experience amassed over the years, BMB is able to guide the customer to make the right choice to meet any production need.
FLIP-TOP CAP
-
This type of closure has become increasingly more popular in every-day use both for personal hygiene such as shampoos, lotions, cosmetics etc. and also for containers for the household cleaning detergents.
It is a basic article requiring high technology.
The BMB control system allows the programming in a simple and effective way any moulding sequence, even the most complex. Any hydraulic, pneumatic or electric movement can be freely set to work in a perfectly coordinated sequence.The use of machines with two or more injection groups allows the realization of complex caps and closures with modern and attractive design.
STANDARD BOTTLE CAPS
- The continuous trend towards weight reduction makes the production of caps for mineral water and soft drinks a complex technological challenge. The eKW Full Electric injection molding machines ensure the necessary performance in terms of speed and precision, with low energy consumption to efficiently produce any type of caps in a low-cost unit.
SPECIAL APPLICATIONS
MODULARITY
- The experience gained over many years has become our bedrock in enabling us to solve the problems related to multi colour/multi material products.
The philosophy we adopt for the design and development of special applications is based upon the use of standard modules which when combined allow us greater flexibility in reaching the optimum solution.
SOLUTIONS
- The ability to be totally flexible in the positioning of additional injection groups enables us to accommodate the varied special application requirements such as: –
• incorporating either rotary table or moveable inserts within the mould
• multi layer materials
• simultaneous moulding of materials whether the same or different.
LARGE PRODUCTS
MODULARITY
- There are no limits to the size of articles to be produced.
The range of larger BMB machines comprises 11 models ranging from 1300 tonnes clamp to 4500 tonnes clamp, either with the KW toggle system (Full Electric up to 2200 tonnes clamp) or with the hydraulic ‘block and lock’ 2 platen series designated as KX models.
9 injection units are incorporated within the ranges with screw diameters from 100mm to 240mm.
Any clamp unit can be combined with any injection unit each with the option of 3 different screw sizes.
With this number of combinations any application can be matched perfectly to suit the final product.
EXTENDED OPENING STROKES
- Thanks to their generous opening strokes, wide tie bar spacing and high clamping force applied over the whole mould surface the KW design is ideal to meet any specific market need.
CENTRAL ACCUMULATER SYSTEM
- All BMB machines benefit from a central accumulator system and in particular the elevated injection speeds enable thin wall section components to be manufactured even large products.
Additionally, the accumulator system is energy efficient as it allows the back pressure holding phase to be maintained without any power consumption even over extended periods.
This is possible as the accumulator system is directly connected to the injection piston under pressure.
