138. How to make plastic - plastic injection molding?
Plastic injection molding has already became very popular in our life, and is the process by which thermoplastic and thermosetting plastic are allowed to melt, then forced into custom molds where they are cooled to take the form of the desired object.
This process begins with an industrial engineer creating a product design. The toolmaker, the molder maker, follows the lead and construct the mould, using metallic materials of the aluminum and steel types, through the use of machines the constructed moulds are made to settle and take the precise shape of the original design. Once the mould designs are done according to specs, it is the only time that the actual production tooling of plastic is carried out.
At this point, the thermoplastic and thermosetting plastic are placed in heated barrels and stirred into a blend. After all plastic materials are properly melted; certain quantities are squeezed into the mould cavity; afterwards, allowing it to cool for a certain period until it hardens into the preferred shape.
The finished products have visible partition lines and gate marks; likewise the ejector pin marks are also distinguishable.
