Abstract
For the proposed tool, the inner surface, in contact with the finished prod, is coated with a space-net forming wax contg a metallic powder. The outer surface, in contact with the tool clamp, is coated with a space-net forming wax contg cheap quartz-sand. Contact between the two surfaces is ensured by a layer of metallic swarf. - For the most economical use of material, an auxiliary pattern may be formed by hand or using simple tools, around the pattern, to a distance of 3-4 mm. The durability of the tool may be improved by the adjustment of the tiller wax ductility. - (pp Dwg.No.0/0)
