Abstract
A method of manufacturing interior trimmings characterized in that an integral portion is extended from the circumferential rim of a skin material in die half, that the substantially whole of this extended portion is sandwiched and fixed between a holder member and that face of the die half which is combined with that of the other die half, that the paired die halves are thus combined with each other to mold a resin body, and that when the resin body thus molded is divided, the extended portion of the skin material is folded round the divided end of its corresponding resin body and fixed to the inner face of this resin body.
Claims6
A method of manufacturing interior trimmings comprising the steps of:
- separating a pair of blow molding die halves from each other, each of said blow molding die halves comprising a concave central cavity portion surrounded by a circumferential rim portion extending outwardly therefrom;
- setting a skin material on an inner face of each of said cavity portions in a manner such that an integral portion of the skin material extends over the circumferential rim of each cavity portion;
- covering an outer face of each extended portion of the skin material with a holder member;
- extruding a parison between the separated die halves;
- combining the die halves with each other;
- blowing pressurized air into the parison to mold a resin body against said skin material to thereby form a molded product;
- separating the die halves from each other after the die halves have cooled;
- removing the holder member from against each extended portion of the skin material thereby defining a space between each extended portion of the skin material and the resin body;
- removing the molded body from the die halves;
- dividing the molded product by cutting said molded product along the space formed between said resin body and each extended portion of said skin material;
- and
- folding each extended portion of the skin material around a cut end of the resin body and fixing each extended portion of said skin material thereto.
