Chen Hsong's largest two-platen machine goes to Germany; caters to fast tooling changes


Through its affiliate Chen Hsong Europe, Hong Kong-based injection moulding machine builder Chen Hsong has not only installed its second made-in-China machine at a German processor but also its largest: a 3,600-tonne two-platen Supermaster SM3600-TP model.

The Supermaster SM3600-TP features “extractable platen technology” that was implemented to enable easy mould changes. In this concept, the machine has three tie-bars of extended length and one of standard length (the upper tie-bar on the operator side). During normal operation, the moving platen moves within the range as limited by the length of the shorter tie-bar. However, when a mould change is required, the moving platen can be retracted back as far as the extremities of the three longer tie bars, thereby leaving one corner of the moving platen detached from the shorter tie bar.

The space thus created can be utilised for mounting of the mould via side entry rather than the conventional method of lifting the heavy mould using a large overhead crane high over the injection machine and lowering it in from above for subsequent bolting to the mould platens. IMG With side entry, the mould can be installed via an overhead crane from a much lower height. This was one of the requirements at the processor due to height restrictions within its plant.

Chen Hsong also says its delivery of the large tonnage machine to an end user in Europe represents a coup since the machine is made in China. Normally, European moulders might be expected to shun such equipment. In this case, however, the German processor initially installed a 178 tonne-JM178-ai-SVP/2 model eight months’ prior to taking delivery of the SM3600-TP machine. Through this initiative, the moulder’s machine operators were able to get accustomed to Chen Hsong machines and became receptive to wider deployment within the organization.

Further, the large machine is supplied together with large Kuka six-axis robot and other peripheral equipment, all of which in combination completed a total turnkey production cell for non-automotive parts and components.

The machine and all associated peripheral equipment are directly connected to a central control system that displays an overview of all critical process and equipment-related parameters. A linkup to a central computer is also provided to ensure traceability of materials, process data, and other product information.

Though the German moulder wishes to remain anonymous, Chen Hsong says that it won’t be the last Chen Hsong injection press to find its way to Germany. At the recent K show in Düsseldorf, Chen Hsong says it received positive feedback from plastic processors with further success in Europe expected.
