EconFluid is a tailor-made hydraulic oil from Boy which it says offers savings
potential in the energy consumption of injection moulding machines
the new IntElect Multi caters to brand leaders seeking innovative and creative ways to integrate multiple colours, resins and sensory features into products, in addition to maximising productivity, as well as being highly energy efficient. With a dynamic motor design, the IntElect range that now includes the Multi machine, provides up to a 20% increase in production output, up to 60% reduction in energy consumption and a faster machine ROI of typically around 18 months, says the company. “The IntElect Multi is our most advanced multi-component moulding machine yet,” says Product Manager Peter Gladigau. “Featuring direct drives, it delivers the highest level of precision and repeatability for multi-component moulding. This ultimately offers shorter cycle times compared to hydraulic concepts. Additionally, the series fills a vital gap for multi-component moulders seeking greater production flexibility using a more compact and energy efficient machine.” Currently available in three machine sizes — 100, 130 and 180 tonnes — injection moulders can select a machine that delivers the level of flexibility and precision required for high volume multi-com- ponent manufacturing. When co-injecting multiple materials, the number of cavities mostly double. In addition, rotating the mould 180° by turntable requires more mould space. The IntElect Multi has been adapted to fit a mould measuring up to 800 mm in height and support a turning diameter of up to 825 mm, with a tie bar clearance of 570 mm on the 180 tonne machine. BMB has developed the 160 tonne eKW-
16Pi/700 fully electric injection moulding machine with low energy consumption for the production of thin-walled food containers with IML technology. At K 2019, the machine demonstrated production of thin wall articles in fast cycle times and with low energy consumption. The work cell produced a circular section food container with a 4 cavity mould and a side entry robot for IML. The goal of this application was to enhance the performance of the entire work cell, aiming at a constant produc- tion of over 7,000 pieces/hour, at the same time

limiting production costs due to the full electric drives of each movement, both the machine and the automation system. The vision control ensures every product is checked in quality and discarded in case of an anomaly. Boy is optionally equipping its ex-works injection moulding machines with an optimised high-perfor- mance hydraulic oil. EconFluid is a tailor-made hydraulic oil offering considerable savings potential in the energy consumption of injection moulding machines. “Extensive tests with EconFluid showed a significantly lower power consumption of the injection moulding machines in comparison with commonly used hydraulic oils,” says Martin Kaiser, Head of Mechanical Design. “For example, power consumption dropped from 1,950W to just 1,765W during a sample cycle. The Boy 35 E consumes up to 10% less electrical energy and significantly increases its energy efficiency.” The company adds that in addition to the
improved smooth running properties and the optimised viscosity, EconFluid has a consistently lower oil temperature. The effect is a significant reduction of the energy required for oil cooling. In long-term tests EconFluid also ensured longer replacement intervals. With appropriate care, EconFluid can be used for up to five years, says Boy.
