상기 표피재는 표피층과, 표피층의 이면에 합판되는 폼층으로 구성되고; 상기 폼층은 표피층의 이면에 접촉하는 저밀도의 상층과, 수지가 사출되는 고밀도의 하층으로 이루어지며; 상기 하층은 용융수지의 열과 압력을 차단하는 것을 특징으로 한다.
Method for manufacturing a car for crash pads in accordance with the present invention comprises a skin material to the upper mold insert; Supplying a base material of the liquid state resin through the injection port of the lower metal mold; Maintaining the shape of the crash pad made of a molded skin material and the substrate is cooled after haphyeong the upper mold and the lower mold; And a step of taking in demolding the mold the molded article after the upper mold from the lower mold; comprises a, the skin material can be a manufacturing process, by integrally molding the base material without a separate bonding process after the insert to the low-pressure injection into the mold for the reduction, and it characterized in that the production time can be shortened.
The skin material and the skin layer, is composed of a foam layer that is on the back surface of the laminate skin layer; The foam layer is made of a lower layer of the low density of the skin layer in contact with the back surface of the upper layer and, a high-density resin which is injection; The lower layer is characterized in that to block the heat and pressure of the molten resin.
