摘要： A process for producing a bumper for a vehicle uses a first step of injecting an outer layer forming material into a bumper forming cavity through a gate in a mold, and a second step of injecting a core forming material, thereby allowing the core forming material to flow into the outer layer forming material existing in said gate and said cavity, while allowing the outer layer and core forming materials to flow within the cavity. In the mold, the volume of a mounting portion forming area of the bumper forming cavity is set so that the thickness t.sub.1 of at least a mounting portion of the bumper for mounting to a vehicle body to extend laterally from a central portion of the vehicle body can be larger than the thickness t.sub.2 of a bumper main portion excluding the mounting portion, and the gate opens into the mounting portion forming area. Thus, the outer layer forming material can be allowed to flow substantially uniformly over the entire cavity, thereby enhancing the filling rate of the core forming material.

摘要： An outer layer forming material is injected into a cavity in a mold and then, a core forming material is injected, whereby the core forming material is allowed to flow into the outer layer forming material existing in the cavity, and both the materials are allowed to flow within the cavity. The cavity has a main area for forming a bumper main portion, and side areas for forming bumper sides. A relation, d.sub.1 >d.sub.2 is established between a distance d.sub.1 determining a bumper thickness of a first section for forming an upper portion of the bumper main portion and a distance d.sub.2 determining a bumper thickness of a second section for forming a lower portion of the bumper main portion. A relation, d.sub.3 >d.sub.1 is established between a distance d.sub.3 determining a bumper thickness of the side areas and the distance d.sub.1. A film gate opens into the first section. Thus, in the main area and the side areas, the times required for the filling of the outer layer forming material to be completed are substantially equal to each other.

摘要： In producing a molded article of a synthetic resin, the following steps are used: a step of injecting an outer layer forming material into a molding cavity through a gate in a mold; a step of injecting a core forming material to allow the core forming material to flow into the outer layer forming material existing in the gate and the cavity and to allow the outer layer and core forming materials to flow within the cavity, thereby advancing the formation of the first construction portion; a step of allowing a front portion of the core forming material in a flowing direction to break through a front portion of the outer layer forming material in the flowing direction to flow into said cavity, thereby advancing the formation of the second construction portion under advancement of the first construction portion; and a step of pushing both the materials existing within the gate into said cavity by the outer layer material, thereby completing the formation of the first and second construction portion. Thus, it is possible to mass-produce a molded article of a synthetic resin including the first construction portion having a sandwich structure including a core and an outer layer, and the second construction portion having a single-layer structure.
