2.1.1. Melt Temperature

Melt temperature is the temperature required to melt the plastic material in a pellet formed in the screw barrel of the injection moulding machine before the injection stage to fill the mould cavities [84,85]. Some researchers reported that melt temperature is a significant processing parameter that causes warpage defects on the moulded parts produced. The relationship between melt temperature and the flow of molten plastic into the mould cavities through feeding system has been studied and it was reported that the amount of material flow into the cavities is affected by the melt temperature [84,85].
