| Abstract: | Rapid manufacture of stainless_steel moulds by using the plasma spray technology based on rapid prototype / rapid tooling shortened the mould developing cycle by 60% and lowered the development cost by 80_85%, compared to the conventional method of manufacturing stainless_steel moulds. It thus quite fits for new product development and urgent production of parts in small quantity. The principle of this technology was introduced and the critical techniques were discussed. A stainless_steel mould manufactured on trial with this technology possesses a stainless_steel sprayed layer of 5mm thick, surface hardness of 34.4HRC and surface roughness of Ra=0.2_m after polishing. |
