MACHINERY
At the K 2025 fair, BMB will be exhibiting four highperformance moulding cells that reflect its extensive experience and far-sighted vision. Hybrid and electric solutions for thin-wall packaging, bottle caps, and IML containers, focused on productivity, reliability, and energy efficiency.
The HP series, BMB’ s workhorse for the production of thin-wall packaging, combines high injection speeds, a dual servo valve, and accumulators with a KW clamping unit that is able to ensure impeccable platen parallelism. This allows for very rapid cycles and the production of particularly demanding thin-wall items, as well as extremely consistent shot weights. The machine also stands out for its high energy efficiency thanks to a fully electric toggle-joint clamping unit driven by direct motors and recirculating roller screws, an electric plasticising unit equipped with a torque motor, and a servo pump assisted hydraulic injection system. The iQ-Pump turns down the motor-pump unit after charging the accumulators, so as to ensure the necessary energy supply at all times and to significantly reduce consumption.
EKW45HP / 3450WP PRESS FOR BOTTLE CAPS The second moulding cell incorporates an eKW45HP / 3450WP hybrid machine with a clamping force of 4,500 kN, designed for the production of water bottle caps with a 96-cavity mould and a cycle time of approximately 3.2 seconds. This machine is the first model of the new BMB range specifically intended for caps and closures. This press stands out for its sturdiness, speed, and compact size, with short opening strokes. Based on a proven modular platform, it is designed to ensure quick response times and accurate melt control, ensuring high quality and repeatability. The centrepiece of the machine is a very light injection piston that moves extremely quickly during the moulding cycle while the entire injection unit structure remains stationary. The hydraulic ejector ensures a rapid and powerful demoulding action, while the oversize torque
motor optimises the plasticisation of HDPE at a low melt flow rate. The clamping unit has been completely redesigned and now incorporates innovative kinematics that reduce opening and closing times while ensuring the perfect parallelism of platens. On top of all, this machine is extremely durable and guarantees continuous production over the years. For this reason, the machine on display at the fair has been designed to provide uncompromising reliability and performance in a strategic sector like beverage. The moulding cell is completed by an in-line visual inspection system and automatic unloading of the inspected pieces into packaging containers.
EKW16PI / 700 FULL ELECTRIC PRESS FOR FOOD GRADE CONTAINERS The third cell features the eKW16Pi / 700 Full Electric injection moulding press dedicated to the production of 100-ml food containers with a clamping force of 1600 kN, a 4-cavity mould and an extremely rapid cycle time of approximately 1.95 seconds. This fully electric machine delivers high performance, with higher injection, opening, and closing speeds, combining productivity and energy efficiency even in the most demanding applications. The cell has been designed to produce at least 177,000 pieces per day with over 44,000 opening and closing movements daily, running non-stop for years. BMB aims to combine extreme productivity levels with the high energy efficiency typical of electric presses, challenging competitors in terms of reliability, low consumption and high performance, supported by its partners that supply automation systems and the machine’ s moulds. The innovative will be delivered directly to a European customer after the exhibition. The 550-ton injection system can inject PCR materials at speeds exceeding 1,000 mm / s, with a peak speed of approximately 1,500 mm / s. The bucket handle, made of virgin polypropylene to ensure maximum strength, can be replaced with a metal handle in-process thanks to an advanced automation system. The machine has two injection units in piggyback configuration: one unit is fully electric and can temporarily suspend the injection of the second component in order to produce the required batch. The mould incorporates a next-generation Oerlikon hot runner- the result of significant efforts in research and development- which reduces maintenance while ensuring quality and consistency.
