ABSTRACT:
Molded product and method for providing a desired surface-hardness for its surface by means of a simple molding technique through several steps comprising the cutting of a thermoplastic film or sheet to the same form as the exterior form of the product, the placing of the cut piece on a mold-cavity surface, and the injecting of a molten resin for formation of the product into the mold cavity under a high pressure. The thermoplastic film or sheet is subjected, in advance, to a hard-coating treatment on its surface and a curing treatment to cure the agent thereon thereby forming a hard-coating layer on the surface of the product.
