5. Implementation and applications
High-density polyethylene is a thermoplastic, and adopts the same processing techniques.
5.1 Injection
A distinction can be made between:
single injection;
bimaterial injection molding, which produces parts with a skin that gives them their appearance and characteristics, and a core made from lightweight or recycled materials;
co-injection of gas into HDPE, which has a number of advantages: lighter hollow parts, less shrinkage, better surface appearance, less distortion, lower internal stresses, reduced clamping force and shorter cooling time; but also disadvantages: impossible to use a multi-cavity mold, hole – to be plugged – in the part at...
