Abstract (en)

[origin: WO02078877A1] The invention concerns a method for treating moulds made of refractory material or shell moulds for moulding disposable patterns of metal castings in particular of aluminium alloys in order to increase their speed of solidification. The invention is characterised in that prior to and/or simultaneously with the casting step, it consists in applying on the outer layer of the shell moulds a metallic material in the form of small-size particles.
