Plastic Injection Moulding is a very tedious job to go through that takes years of experience and expertise to perform a decent job. With the aid of technological advancements, we enjoy a more consistent and efficient work process from innovative machineries. The essential elements in plastic injection moulding are as follows:
The plastic material is introduced into the injection moulding machine. There will be heated barrels equipped within the plastic injection moulding machine with reciprocating screws driven by either a electric or hydraulic motor. These feed the plastics into a temperature with a channel system of gates and runners. The screw which acts as a ram during the injection process then melts the plastic into liquid form for moulding. Then the plastic is injected into the mold that would define the shape of the finished product.
The injection pressure is high depending on the materials being processed; some could reach up to one thousand atmospheres. There are so many oem components are manufactures this way, some would be hardened or plated in further process. The cost of plastic injection moulding depends very much on the design associated. The mold can consistently manufacture the same component in a repeating process or incorporate multi cavities. This is how bulk orders are manufactured using the same tool repeatedly with a single injection. The variants of plastic injection moulding process include multi-shot; insert molding, structural foam moulding, assisted molding etc.
Today the plastic injection moulding process is controlled by built-in-chip or computers. Acting on the sensor fed information; it is able to control all the actions and processed in the machine. As a result, we get a much précised, accurate and efficient output and shot to shot quality.
