Abstract:

A method of manufacturing a molded product of a synthetic resin, characterized by comprising the steps of forming a container and a panel type surface layer member by subjecting a synthetic resin sheet to two-stage thermoforming; and forming an outer shell reinforcing layer on a rear surface of the surface layer member by subjecting a glass fiber-reinforced or non-glass-fiber-reinforced ABS resin or AS resin to injection molding, the method being capable of manufacturing molded products, such as a container and panels of a synthetic resin which have a strength and a rigidity high enough to withstand severe thermal resistance tests, a high quality and light weight, and which are capable of being obtained at a low cost and recycled easily.
