  • Injection Moulding Of Plastics Or The Like (AREA)

Abstract

PURPOSE: To obtain an article which is excellent in smoothness of surface and rigidity by a method wherein glass fiber reinfroced preliminarily molded resin is buried in a cavity and then the resin with which no glass fiber is combined is injected in the interstice under the condition wherein the temperature is higher than the melting point of a preliminarily molded part by more than a fixed temperature.
CONSTITUTION: A preliminarily molded substance is prepared by injecting the resin 1 with which glass fiber is combined and buried in the cavity of a metal mold, and in the interstice formed between the preliminarily molded substance and the cavity of the metal mold, the resin 2 not containing glass fiber and heated to have the temperature higher by 30° or more than the melting point of the preliminarily molded substance is injected and formed into a united state. Since the glass fiber reinforced resin 1 is coated with the resin 2 with which no glass fiber is combined, the embossing of glass fiber is not found and thus the surface can be made smooth. It is allowed as well that the preparation of the preliminarily molded article with the resin 2 precedes the injection of the glass fiber reinforced resin 1. Since the injection is performed under the temperature higher by 30° or more than the melting point of the preliminarily molded substance, the adhesiveness of both layers is also excellent.
