High-tech machines and processes at the Chinaplas in Shanghai

WITTMANN’s range of granulators will be shown at the Chinaplas as well. The exhibits will include the MAS 2A grinder, the screenless beside-the-press granulator models Minor 2 and Junior 2 Compact, and two beside-the-press granulators from the G-Max series, a G-Max 12 and the powerful G-Max 33. The granulators from the G-Max series are designed for inline recycling of sprue from injection molding machines with clamping forces of up to 4,000 kN. They stand out by their high degree of efficiency and compact dimensions, and are equipped with a sound-insulated cutting chamber, to minimize the noise level.

In the area of materials handling, WITTMANN will demonstrate its expertise with the stand-alone loaders FEEDMAX S 3-net as well as central separators from the FEEDMAX B series. Both types of material loaders offer maintenance-friendliness, process reliability and easy operation.

The blenders presented by the company will be a GRAVIMAX G34 gravimetric blender with a throughput of up to 200 kg/h and a DOSIMAX volumetric blender. The GRAVIMAX comes with wear-resistant, high-precision stainless steel valves. Its metering accuracy is ensured by RTLS technology (real-time weighing). Two weighing cells are active throughout the entire metering cycle, which measure precisely down to the gram and thus ensure a consistently high parts quality for every shot.
