Abstract (EN): The conversion of rapid prototyping models into metallic tools for plastics injection using a ceramic moulding process is presented. The process main steps used in this experimental work were: production of the model (by rapid prototyping or conventional techniques), conversion into a silicone mould, production of a ceramic mould by casting a ceramic slurry that suffers a sol-gel reaction into a box, casting an alloy and finishing. Processing parameters like preheating of the ceramic moulds, pouring temperature and heattreating of the moulds have a very important influence on the final characteristics of the metallic tools. This work presents the influence of the above parameters on the surface roughness, mechanical strength, dimensional changes, microstructure and capacity of details reproduction of the metallic tools.
