In areas of mass accumulation or large wall thicknesses, this volume contraction of the melt is increased, whereby the reducing volume cannot be replaced by new melt as the injection channel has already so...") | ||||

In this process, the volume and dimensions of the moulded part decrease in comparison to the original mould or moulding ne...") | ||||
