Abstract

PURPOSE: To obtain cheap molds easily by forming a half mold with a thermoplastic resin skin coated on the upper or the lower surface bounded by the specified line of a master model and similarly forming the other half mold with the skin coated on the other surface.
CONSTITUTION: A master model 1 is prepared by the use of proper material such as hard urethane, plaster, etc. at first and a parting line 2 is provided to decide the boundary between a male and a female mold. Thermoplastic resin (polyvinyl chloride, vinyl chloride resin being desirable) for the male mold is melted and adheres onto the above-mentioned line 2 and is cooled and cured to form a resin skin 3a. The female mold 3b is made in the same method. It is preferred to give 2W10mm to the thickness of resin skin in the field of foamy molding
USE: Molds for moding foamed substances such as urethane foams, etc.
