HQ Mould has got advanced machines and teams of designers and developers to carry out the process of manufacturing injection plastic moulds smoothly. The various stages of manufacturing have been mentioned here.
This is the first stage of the process in which the halves of a steel or aluminum mold are joined together using a hydraulically powered machine. This is done prior to injection of plastic material into the mold.
Injection
In this stage, the plastic material is heated and high pressure is applied until it melts. The molten plastic is then injected into the mold. Various factors such as injection power, injection pressure and the shot volume determine the injection time.
Ejection
The molten plastic starts to cool and solidify inside the mold. Ejection stage comes after the plastic has solidified completely. The ejection system of the machine ejects the hard plastic out of the mold. Mold releasing agent is also used to aid in the ejection of the plastic.
The plastic mould is subjected to quality control in order to detect any kind of defect in the part. Warping, flash defects and high moisture content are some of the common defects.
