Wear properties injection moulding

A key reason for selecting high-performance plastics is the precision with which finely detailed parts can be injection moulded from them. In addition, their excellent slip properties in sliding contact with other materials, high impact strength and low wear ensure reliable fiinctioning of the application long-term. 

The binder component should be kept as low as possible, as this reduces shrinkage during sintering, thereby allowing closer tolerances on the finished part to be maintained. The binder component of injection moulding masses is between 35-55% by volume. If the binder component is too low, the quahty of the injection moulding properties is reduced and the wear on the machine and injection equipment increases greatly.
