ABSTRACT:
An injection molding machine includes a platen having a plurality of regularly spaced mold element-receiving chambers adapted to receive any of a number of various mold elements substantially wholly within the stationary platen. A hot manifold system is included between the stationary platen and a plastics injector unit, which includes a plurality of blocks independently coupled to the fixed platen, each block having channels through which the plastics material can flow, the channels of adjacent blocks being coupled by a coupling unit. The machine is particularly designed for quick inexpensive mold changes, and has particular utility in laboratory testing of mold designs and small low-capacity production in satellite plants.
