Title:
METHOD FOR MANUFACTURING MOLDED BODY OF FOAMED PARTICLES HAVING SKIN MATERIAL LAMINATED THEREON
Document Type and Number:
Japanese Patent JP2002067067
Kind Code:
A
Abstract:

To provide a method for efficiently manufacturing a molded body of foamed particles having a skin material laminated thereon wherein the mutual fusing strength of the foamed particles and the fusing strength of the skin material and the foamed particles are large, in regard to the manufacturing method of the molded body having a structure wherein the skin material is laminated on the surface of the molded body of the foamed particles.

In this method, the foamed particles filled in a molding space part formed between a first molding tool wherein the skin material is disposed along the inner surface and a second molding tool having a large number of through holes along the wall surface are heated and fused and thereby the molded body of the foamed particles having the skin material laminated on the surface is manufactured. The method comprises an exhausting process wherein the air being present in the molding space part is exhausted after the foamed particles are filled in this part (i) and a heating process wherein the foamed particles in the molding space part are heated and fused by introducing a heating medium into this part from the through holes formed in the wall surface of the second molding tool (ii). The heating process is executed at least twice separately with the position of introduction of the heating medium into the molding space part changed sequentially.
