It's a common challenge not only in plastic processing companies. Shrinking cannot be predicted with great accuracy. However, exactly this shrinkage behaviour influences the dimensions of the injection moulded part. The quality of injection moulding tools cannot be assessed by a simple measurement. The necessary accuracy can only be determined by inspecting the parts manufactured using it.
