Aluminium moulds for plastic processing industry

Objective

The mass production industry is confronted to consumers with stringent requirements demanding for products tailored to their needs with reduced costs and time-to-market. Moulds made of aluminium alloys, have successfully entered the market of plastic blow-moulding and the thermoforming. Because of insufficient mechanical properties, aluminium moulds do not yet exist, except prototype or pre-series moulds, on the plastic injection market nor resin transfer moulding.

Aluminium moulds, however, present remarkable properties compared to steel moulds:
1) at least 30% gain in machining time of the fabrication of the mould;
2) at least 30% gain in productivity since the thermal conductivity of aluminium is superior to that of steel;
3) Gain in quality of plastic injected parts since the cooling is more homogenous;
4) weight saving: density of aluminium is 3 times lower than steel. This leads also to easy handling for big moulds.
