发明名称 Molding process and apparatus utilizing memory metal alloy springs
摘要 A number of distributed springs, fabricated from memory metal alloy, are connected to a die in a molding assembly. When heat is applied to the springs, they expand with sufficient force to mold a resin-impregnated composite material over a contoured mold form. The heat may be simultaneously applied to the composite material for achieving curing while molding occurs. Upon removal of the heat, the springs contract thereby allowing removal of a finished molded product.
