Abstract
A method for producing a multilayer molded article by facing a preheating panel on which a preheated skin material is placed towards one of upper and lower molds, forming a closed space by the mold and the preheating panel, evacuating the closed space to suck the skin material onto a surface of the mold, removing the preheating panel, supplying a resin through a resin conduit with closing the molds or temporarily stopping mold closing, and finishing the mold closing. By this method, a multilayer molded article having a resin body which is made by deep drawing or has a complicated shape and a skin material laminated on a surface of the resin body can be produced.
