Alternative Methods Using in Mold and Core Technologies

Technologies of producing molds and cores used for producing castings of special alloys, of complicated shapes and high functional properties, are described. Castings manufactured in these processes, mainly for the cosmic, aircraft, automotive, and armament industry, are of the highest quality. The Rapid Prototyping (RP) process deserves a special attention. The base of the whole process is the digital 3D model made in the CAD environment. The RP is the additive method, which means it is based on a gradual placement of a material, layer after layer. This process is very efficient in small series and in piece production.
