In hall 13, stand B 45, a Forza F550T (5,500 kN clamping force) — with a single-cavity mold — produces polypropylene buckets (460 grams) in cycle times of less than 20 seconds. The all-electric Elettrica EL130T (1,300 kN) shows its performance in the high-speed production of precise plug-in bricks for the toy industry with a 16-cavity hot runner mould. The cycle time is specified as being less than ten seconds. The injection molding machines, aimed at technologically ambitious industries, are characterized by a maximum of process-relevant dosing and control technologies from Germany and its neighboring countries. As a result, the user can rely on control and regulation technology that meets current requirements in terms of reliability, safety and comfort. The German hydraulic pump technology used at Forza guarantees high efficiency and precision. Remote maintenance is carried out via Keplast Servicenet.

The highly efficient all-electric drive is based on international performance standards and state-of-the-art technology. The main qualities include good stability, fast response, energy saving (95% efficiency) for environmental protection, very high repeat accuracy and simple operation. With no hydraulic oil or oil vapours, no sealing problems and no annoying noise, it is ideal for use in clean room production facilities. The “footprint” of this advanced IMM is surprisingly modest.

Even more: parallel movements – by means of individual servomotors – reduce cycle times. Synchronous multi-axis movements, ejection and dosing functions, for example, reduce the dry cycle time of the smallest Elettrica to less than two seconds. Highly sensitive load cells for injection pressure monitoring and high frequency control processors provide fast response to stable control of the injection and filling process and the pressure holding phase. The overall benefit for the user: higher productivity at lower unit costs.

The functional expandability of the Elettrica in conjunction with the ergonomic design concept aims for efficient operation and simple maintenance. The control panel can be rotated in several viewing directions. An open platform operating system is available for intelligent networking, user-friendly programming and convenient automation.

The K 2022 exhibition program also includes the Forza F550T two-platter machine. This series of advanced IMMs is available with clamping forces from 4,500 to 70,000 kN). With its entire product range, LK IMM meets the requirements of established markets and growing regions for maximum accuracy “fast and right from the start”, the lowest possible power consumption and an attractive price/performance ratio – in particularly in the automotive, food and packaging, medical/pharmaceutical, optical, appliance, electrical/electronic, appliance and toy sectors. In the heavy IMM sector, the economical production of buckets, large containers, transport boxes and pallets plays an important role. The machine is designed as a particularly compact unit. Thanks to its multifunctional process capability, it is ideally suited to the requirements of, for example, the production of automotive components. It offers exceptional performance in all phases of the cycle, even in start-up mode. The use of servo pump and electric drive technology provides energy savings in harmony with high injection performance and precision.
