Dual-face surface foaming car interior trim part and forming process thereof

Abstract

The invention discloses a dual-face surface foaming car interior trim part. The part comprises an upper surface, a foaming layer, an insert and a lower surface. The foaming layer is a glass fiber reinforced polyurethane foaming layer, the insert is the insert embedded in the foaming layer during forming, the upper surface and the lower surface completely wrap the foaming layer and the insert, andthrough one-time forming of the glass fiber reinforced polyurethane, the integrated car interior trim part is subjected to composite molding. According to the dual-face surface foaming car interior trim part, one-time foaming molding is achieved, the aim is easily achieved, the forming efficiency is high, the cost is low, and the combination strength is high. According to the dual-face surface foaming car interior trim part, the raw material cost of the one-time molded product is small, and the weight is small. The invention further discloses a forming process of the dual-face surface foamingcar interior trim part. The product is attractive in appearance, small in weight, and capable of reducing product weight, and meeting the car lightweight needs, meanwhile, the labor efficiency is improved in a multiplied manner, and the cost is reduced.
