Abstract

PURPOSE:To shorten the molding cycle dispensing with any coating process of die releasing agents and any cleaning process of dies by hardening by reaction a material resin injected after a vacuum molding of a thermoplastic resin film placed into a molding die. CONSTITUTION:A vacuum suction hole is provided on an RIM molding die and placed on the die, a thermoplastic resin film is vacuum molded with a vacuum suction device closely adhering the inner wall thereof. A complicated or fine pattern such as grain and marble patterns can be aplied on one side of the thermoplastic resin film. Therefore, a material resin is injected by a normal RIM molding method and hardened by reaction. Combining a thermoplastic resin film and a resin molding, a resin molded product is obtained having a patterned thermoplastic film on the surface thereof.
