PEX POLIDAN®  TA, S/I 10, S/I 20 in injection moulding are forced into the mould at very high pressure. The mould is then cooled, the halves are opened and the finished article is ejected for small parts, lots of moulds are often mounted on one machine and the molten plastic is injected into them all simultaneously. Injection moulding can produce far more complex items than extrusion, but it isn't a continuous process. The finished articles it produces are in their final shape and can be rigid or soft, compact or cellular. Injection blow moulding allows the production of hollow articles.
Several PEX Polidan ® grades can be used for moulding objects of different shapes: customer can choose fluidity and density that better fit their machinery.
A fast growing application for injection moulding for PEX are fittings for pipes. Thanks to its excellent mechanical resistance and high temperature operating conditions, PEX can be used instead of Polybutylene, Polysulphone and Polyamide to produce fittings for hot water and gas pipes. This solution can allow to build an all-PEX system, without weak points.
