Setting new benchmark in silicone processing

The BENCHMARK S3 from DESMA is a vertical machine featuring a totally new design aimed at setting high standard in rubber and silicone injection moulding.

Sharp lines, excellent accessibility, carefully  thought-out and designed conduit arrangement in conjunction with an innovative design and robust overall construction offer the best platform for a long machine life in tough production environments. 

“DESMA launched the S3 prototype at K2010 then went back to the drawing board to refine and improve its design,” according to DESMA Managing Director Martin  Schürmann. “This model can successfully meet the requirements of customers for machines that are highly efficient, energy-saving and environment-friendly.”  

DESMA’s expertise in the rubber and silicone processing has rendered it highly capable of determining the market’s preferences. “Our latest machines come a long way in terms of features,better material and energy efficiency, improved productivity, better economics,”  Mr.Schürmann adds.  

Energy-saving and zero waste

The S3 offers for the first time a hydraulics with servo-drive called ServoGear. This energy-saving hydraulic concept saves around 45 percent of the total energy consumption, thanks to its 2-pump system. In case of a 4-minute cycle, the consumption of kinetic energy reduced by 45 percent means at least 10 percent of saving in overall energy consumption. ServoGear also enables exact positioning and impressively low noise levels.

The DESMA patented FIFO-Advanced injection unit has also been redesigned and offers now a bundle of options. For example large silicone stuffing systems can be integrated even with small injection volumes. The new 19 DRC 2020 HT visualisation unit features the Haptic-Touch innovation, opening the door to many new possibilities. The service-friendly covering offers integrated vapour extraction and much reduced noise generation together with the improved overall ergonomics: all adding up to significantly lower stresses on the operator. 

“The machine’s Touchscreen control features 152 pages to set up the various processes, which adds to the machine’s uniqueness. The zero waste technology applied enables savings in materials by as much as 60 percent,” according to Mr. Schürmann.

The injection unit can be fitted with the actively driven feed roller, ActiveFeed, which enables the handling of thicker material strips. The injection unit can even feed in material strips with serious fluctuations in width and thickness, which in turn creates greater flexibility in material procurement, a benefit which really can cut material cost.

The S3 version also features a newly developed non-return system: this hydraulically operated non-return valve is known as PlastControl. The result is a much improved level of precision in material dosing and an approx.50 percent higher level of injection accuracy. And what is more, material changing can be effected more quickly and easily.

All new options for injection units are of course available for the new FIFO Advanced and FIFO B Advanced.

The Iso+ heating platens of DESMA minimise the radiating heat by way of a rotating insulation. This reduces energy losses and the heat pollution the operator is exposed to. At theLebron Soldiers X 10
