Polypropylene resin article having skin material lined with foam layer |
| abstract |
A multi-layer molded article comprising a polypropylene resin body and a skin material lined with a foamed layer, obtainable by a method comprising the steps of: n providing a pair of upper and lower molds (1,2) which are slidably moved at an engaged part (6) and in which a cavity clearance (t) is freely set, n placing a skin material (7) lined with a foamed layer between said upper and lower molds and supplying a molten polypropylene resin containing a chemical blowing agent through a resin melt conduit which is provided in said lower mold (2) or said upper mold (1) when said cavity clearance (t) is between (C + 15) mm and (C + 50) mm where "C" is the thickness of said skin material lined with the foamed layer, n lowering said upper mold (1) at a rate of from 10 mm/sec. to 100 mm/sec. and pressing said resin melt at a pressure of from 5 kg/cm 2 to 100 kg/cm 2 to fill the cavity ends with said resin melt to complete molding of a body of said resin, n pressing said body for 1 to 30 seconds after completing molding to form a skin layer, n then, lifting up said upper mold 1 to decrease the compression pressure of said skin material lined with the foamed layer to a pressure lower than the blowing pressure of said polypropylene resin to form and solidify a foamed body, and n again lowering said upper mold (1) to apply a pressure of from 1 kg/cm 2 to 20 kg/cm 2 on the molded article and cooling said article in said molds. |
