US-based maker of engineering presses, Wabash MPI, has introduced a hybrid servo-pneumatic liquid silicone injection moulding machine. The Microlim machine is intended for clean room and medical applications, and is designed for shot sizes from less than 1cc up to 15cc.
The company claims excellent shot-to-shot repeatability. The Microlim’s features include a patented plunger design with “centre shutoff” nozzle for accurate shot size control. The injection head can be removed for cleaning and changing, a feature which the manufacturer claims makes it ideal for short run applications. The machine has a maximum clamp force of 17 tons and platen size of 229mm x 229mm.
