High pressure injection moulding
High pressure injection moulding is the ideal technique for large series of thin-walled products. Steel moulds are used.
How does high pressure injection moulding work?
The plastic is heated in the screw and injected into the mould under high pressure.
The mould is filled completely and pressure is added to prevent the product from falling in.
When it has cooled down, the mould opens and the product is removed.
