SIG PLASTICS, of Germany, has introduced a PET preform injection moulding machine which claims a 15% higher performance and reduced production costs over its predecessor. With a high capacity plasticising unit of 400g/second, the PREMAX 96 features gentle plasticising achieved by a PET screw developed specifically for the purpose. In addition, reduced screw speed and peripheral velocity means raw material is exposed to less shear forces, and hence reduced temperature.
