Research and Development of Rapid Casting Process
The rapid casting process,which is an integration of rapid prototyping and the casting process,is introduced.the expandable patterns,die of expandable patterns,pattern,pattern plate,casting mould,casting cores and mould shells can be made directly or indirectly by rapid prototyping,then the metal castings can be manufactured rapidly by conventional casting technology.By introducing the principle of the rapid prototyping into the moulding process,the binders and catalyst are sprayed on the moulding sands or ceramics powders,the casting mould can be obtained after curing and coated by refractory coating,then can be used for pouring of liquid metals.Rapid casting processes can increase the production efficiency and is suited for the small batch of various complicated components.Hence,it has a good prospect.
