Desma to showcase Benchmark S3 vertical machine in Shanghai

On the S3 machine the company presents with ServoGear hydraulics with servo drive. This hydraulic concept offers an energy consumption reduced by 10?-?13 % (depending on cycle and equipment) as well as precise positioning and a low noise level. The clamping unit was redesigned and is now fitted with wider opening strokes and with a hydraulic oil supply that is largely piped respectively integrated into the mould carrier platens. Thus, the number of hoses was reduced to a minimum for easier maintenance.The injection unit is now presented under the name FIFO Advanced. It provides new possibilities, e. g. big silicone stuffing systems can now be integrated even in case of small injection volumes. Moreover, the injection unit can be equipped with the actively driven feeding roller ­ActiveFeed which allows to process double the strip thickness as against comparable units. The injection unit further enables the intake of strongly varying strip widths and thicknesses, thus creating more flexibility in purchasing the materials.The machine also features the hydraulically operated non-return valve PlastControl. The result is an improved precision in material metering and a plasticising precision increased by 50 %. This is advantageous for the processing of low-viscosity materials such as liquid silicone, because the non-return valve can be actively closed.The operating panel DRC 2020 HT integrates a touch-screen which provides users not only with visual information, but also haptic feedback. The operating terminal can also be retrofitted on machines with the control system generation DRC 1210/DRC 2010.The S3 features a covering which apart from serviceable big doors includes an integrated ­extraction of material vapours. Together with its low noise level the machine ensures comfortable operation.
Furthermore, the hydro-mechanical quick-lock system QuickLock simplifies the mould changing. This system also comprises the quick clamping of mould centre platens.In addition, the company will also inform about its full range of cold runner systems.
