Injection moulding of polyester moulding compounds


Polimery 1984, No 5, 169



DOI: dx.doi.org/10.14314/polimery.1983.169

Summary

The rheological properties and results of technological studies on the injection moulding of home-made Estrodur polyester moulding compounds have been discussed. They can be injection moulded with the Polish MONO-mat duro injection moulding machines. The effect of the moulding parameters on the properties of moulded specimens has been characterized. A considerable anisotropy of the mechanical properties and shrinkage has been observed. It depends on the direction of material flow during injection moulding in relation to specimen dimensions. The mechanical properties of the injection moulded specimens are interior to those of the compression moulded ones.
