Abstract

PURPOSE: To obtain an insert shape having excellent adhesive property and bonding property by previously heating the insert in metal at a temperature, which is higher than the softening point of denatured polyolefin and lower than its deterioration temperature.
CONSTITUTION: An insert part 2 consisting of molding resin 1 and metal which can be bonded is heated at the temperature, which is higher than the softening point of the molding resin and lower than its deterioration temperature, and the molding resin is supplied into a die and molded. The insert part is expanded throuth heating, is hardly affected by the contraction of the molding resin when the molding resin contracts after molding, and displays an effect lowering residual stress. The denatured polyolefin of every kind apply as the molding resin. An extracting jig 3 can also be attached to the insert part 2.
