When faced with a challenge from a processor requiring a shot weight of 110 kg, Chen Hsong turned to one of its large two-platen machines with a special modification. The solution was to configure a 6,500-tonne SM6500-TP injection molding machine with two parallel injection cylinders of 55 kg shot weight capacity each in a “Y” configuration.
Chen Hsong recently delivered the unit to Australian processor Trident Wastewater Services (Adelaide, SA) for molding large septic tanks from polypropylene in a single color. Shot volume is an incredible 152,094 cubic cm.
Further, two injection cylinders deliver a high degree of processing flexibility to the molder lest it want to use the machine for another application in that minimum shot size per cylinder is just 15 kg. The option of using just one injection cylinder is possible.
