There are many advantages associated
with plastic injection technique for making plastic moulds. Plastic injection
moulding enables manufacturing of moulds with even highly complex designs.
Furthermore, it is also a very quick and efficient method of plastic mould
manufacture. The whole process is also automatic as machines are used for the
entire process. HQ Mould is the company to hire if you are looking for high
quality plastic mould China.
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.
Clamping
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.
