The complexity of the properties of plastic materials determines the complexity of the injection moulding process. The performance of plastic materials varies greatly depending on the variety, grade, manufacturer, or batch. Different performance parameters can result in completely different moulding results.
2. Injection temperature
The melt flows into the cooling cavity, dissipating heat due to heat conduction. At the same time, heat is generated due to shearing, which may be more or less than heat transfer, depending on the injection moulding conditions. The viscosity of the melt becomes lower as the temperature increases. Thus, the higher the injection temperature, the lower the viscosity of the melt and the less the required filling... less
