摘要: Method of rapidly producing a contoured part, comprising: designing a computer graphic model of the part, sectioning the graphic model into graphic members which are at least one of blocks or slabs, carving a solid member (14-150 mm in thickness) for each of the graphic members, the solid member being proportion to and enveloping such graphic members, the carving being carried out by accessing two or more sides (opposite sides) of such solid member to at least essentially duplicate the corresponding graphic member, and securing the carved solid members together to replicate the graphic model as a usable unitary part.The method can be modified to make castings by carving wax or foam solid members which are assembled to form an investment pattern, the was pattern being used in a shell mold casting steps and the foam pattern being used in evaporative casting steps.

摘要: An improved method of brazing of two unclad aluminum shapes, particularly for automotive heat exchangers, which brazing joint does not leave a physically apparent layer of brazing material and which effects a stronger, sounder autogenous joint. A thin film of aluminum eutectic forming material (Si, Al-Si or Al-Zn) is deposited onto a zone of at least one of the shapes to be brazed or joined. The shapes are placed in joining relationship to form an assembly with a joint at the zone. The assembly is heated to a temperature to diffuse the eutectic forming material into the aluminum members to form a sacrificial bond between the shapes at the joining zone. It is desirable that at least one of the unclad aluminum shapes to be joined is extruded tubing having a precise diametrical configuration and said film is deposited as a physically vapor deposited layer in a thickness range of 1-50 microns.
