Abstract:
This paper is establishing the influence of the processing temperature on the in-mould (cavity) pressure at
injection moulding of the polymers used for manufacturing of sport products. The processed polymers were:
polyoxymethylene (POM, polyacetal), polyamide 6,6 (PA 6,6), polycarbonate (PC), thermoplastic polyurethane (TPU) and
polypropylene (PP). The injection machine employed was an horizontal ENGEL G/11/10/116/3, model VC 500/110
TECH, made in 2002. The temperature in the injection cylinder nozzle was measured through a DYNISCO Ti422J
thermocouple. The cavity temperature was determined by means of a thermocouple temperature probe, model 2024T,
produced by Digitron Instrumentation Ltd. and the cavity pressure was measured with a transducer, model IDA, made by
Dynisco Europe GmbH.
