Injection moulding machines for packing

A series of high-performance machines that has proved pivotal in the development of BMB and has been continuously updated and improved to provide multiple operational advantages and total reliability thanks to its specific technical features, i.e. large clamping plate dimensions, Voith gear pump, rolled threaded rods both hardened and hard-chrome plated, and bronze nuts in tough nickel, chrome and molybdenum, an in-line hydraulic motor or a direct-torque electric motor to turn the screw, magnetostrictive transducers in all movements and a central accumulator system for all phases of the machine.The widely recognised and admired KW clamping system, which, thanks to its unique design, combines the best features of a traditional articulated mechanism and a direct hydraulic clamping system whose connections bend outwards during the opening phase.
With this design, higher opening and closing speeds can be achieved while ensuring perfect parallelism. In addition, longer opening strokes and zero deflection of the pressure plates are inherent features.
The special geometry of the articulating mechanism means that the clamping force is not only applied to the centre of the mould, but is evenly distributed over the entire mould surface.

BMB has taken all the experience gained in two specific areas, one dedicated to high-speed machines and the other dedicated to all-electric technology, and created this innovative series that combines their advantages, i.e. high performance injection unit, precision, speed, robustness and low energy consumption. What's more, the performance of the control unit, which is easy to programme and offers exceptional flexibility, makes the series user-friendly. All of the above is contained in a wide range of models capable of

meet all requirements, with machines ranging from 160 tonnes to 2,200 tonnes.Thanks to the special KW fastening system, plate deflection is eliminated, perfect parallelism is ensured and longer opening strokes are an added advantage.
The movement of the plate is by means of special recirculating satellite roller screws with direct linear drives, which provide high load capacity and improved performance. The reliability and rationality of the machine has been increased thanks to a reduced footprint, brushless motors, liquid cooling and optimum cleanliness of the mould area.

A new machine concept focusing on efficiency and reduced production costs, offering many benefits: energy savings, reduced water consumption, significantly reduced noise levels, minimal lubrication costs thanks to the use of roller screws operating in closed water-cooled oil baths. These features ensure high reliability, repeatability and accuracy. Thanks to the unique KW clamping system, which completely eliminates deflection of the panel, perfect parallelism is guaranteed while taking into account particularly long opening strokes. The movement of the plate by direct-drive roller screws ensures high load capacity and improved performance. The reliability and rationality of the machine is enhanced by the reduced surface area, water-cooled, sealed brushless motors and thus a mould area free of any contamination.
