LK high-performance injection moulding machines on the home straight

LK high-performance injection…

Luigi Tondi, Sales & Business Development Director of LK IMM Europe (LK s.r.l.), Travagliato (BS), Italy: "Our injection moulding machines are designed for the highest demands in terms of performance, precision and environmental protection, whether automotive, optics or medical technology and all the industries that cannot exist without top quality. To achieve this, we work closely with renowned partners and our customers." In Hall 13, on Stand B 45, a Forza F550T (5,500 kN clamping force) - with a single-cavity mould - produces polypropylene pails (460 grams) in cycle times of less than 20 seconds. The all-electric Elettrica EL130T (1,300 kN) shows its pure performance in high-speed production of very precise plug-in bricks (2.2 grams in ABS per part) for the toy industry with a 16-cavity hot runner mould. The cycle time is specified as less than 10 seconds. The injection moulding machines (IMM), which are intended for technologically ambitious industries, are characterised by a maximum of process-relevant metering and control technology from Germany and its neighbouring countries. As a result, the user can rely on control and regulation technology that meets the current requirements for high reliability, safety and convenience. German hydraulic pump technology in use at Forza ensures high efficiency and precision. Remote maintenance is a matter of course. It is carried out via KePlast ServiceNet. The entire injection moulding machine range from LK IMM is designed for Industry 4.0. Production can be controlled/regulated and tracked with the KePlast EasyNet 4 system.

The all-electric Elettrica EL130T (clamping force range 1,000 to 3,500 kN) "enters" the cleanroom – for three-shift production of precision parts for the medical device, pharmaceutical, cosmetics, optics and electrical/electronics industries. "The documented zerodefect rate is always in focus," says Luigi. To achieve this, the IMM is equipped with a number of valuable features: The conveniently designed process control has a quick availability of thousands of production parameters, which - once 100% optimised - can be reactivated at any time for a follow-up product. This ensures absolute repeatability, provided that the plastic raw material has the same recipe.

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 savings (95% yield) 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 absolutely suitable for use in cleanroom production facilities. The "footprint" of this advanced IMM is surprisingly modest.

Even more: parallel movements - by means of individual servo motors - reduce the cycle times. Synchronous multi-axis movements, ejector and metering functions, for example, reduce the dry cycle time of the smallest Elettrica to less than two sec-onds. Highly sensitive load cells for injection pressure monitoring and high-frequency control processors enable a fast response to stable control of the injection and filling process and the holding pressure phase. The overall advantage for the user: higher productivity at lower unit costs.

The functional expandability of the Elettrica in conjunction with the ergonomic design concept is aimed at efficient operation and uncomplicated 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 programme also features the Forza F550T two-platen 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 demands of established markets and growth regions for maximum precision "fast and right from the start", the lowest possible energy consumption and an attractive price/performance ratio - especially in the automotive, food & packaging, medical/pharmaceutical, optics, white goods, electrical/electronic, household appliance and toy industries. In the heavy IMM sector, the economical production of pails, large containers, transport boxes and pallets plays an important role. The machine is designed as a particularly compact unit. Due to its mul-tifunctional process capability, it is ideally suited to the requirements of, for example, automotive component production. It delivers outstanding performance in all cycle phases - even in start-up mode. The use of servo pump technology and the electric drive lead to energy savings in harmony with high injection performance and accuracy.

Andreas Bexte, LK IMM's partner for Germany. "Raising customer interest and realis-ing deals is partnership by competence: offering long-lasting reliable, economical products with the highest level of European quality, ensuring comprehensive service and respecting customer demands - this has become possible in direct dialogue with the designers, manufacturers and suppliers of components."
