A method of forming a synthetic resin formed article having a double-layer structure of a base portion and a covering portion which covers an outer periphery of the base portion and which has an inwardly curved portion for covering an end portion of the base portion. The method includes the steps of forming a sheet-like material into a predetermined shape by the vacuum forming to obtain a preliminary covering portion; trimming an end portion of the preliminary covering portion obtained in the previous step to obtain the covering portion of the formed article; setting the covering portion of the formed article on one of a pair of dies which constitute a press-type forming die with the curved portion of the covering portion being supported by a slide core located at a forefront position; setting a molten resin which is forming material of the base portion into a gap between the one die and the other die in a state in which the covering portion of the formed article is being set on the one die; clamping the press-type forming die in a state wherein the slide core is in contact with the other die at the forefront position immediately after or in synchronism with the molten resin setting step and causing the molten resin to set to form it; and opening the forming die and then removing the formed article obtained in the clamping step from the press-type forming die.

Method of forming synthetic resin formed articles

An air bag device for an instrument panel has a cover with a hinge and in one embodiment a break-away portion made of thermoplastic material. The cover has a bracket. The strength of the break-away portion is lower than that of the cover. The break-away portion breaks when an air bag inflates. The cover opens rotationally around the hinge. The second embodiment has no break-away portion.

A method for producing a foam base material product composed of a composite sheet having a surface layer and a foam base layer with a securing device fixed on the form base layer. The method includes the steps of preparing an insert part with the securing device integrally fixed thereto, the insert part being made of a beads foam derived from a resin, placing the insert part within a mold, placing the foam base material layer of the hot molten composite sheet on the mold so that it faces the insert part, and closing the mold whereby the composite sheet is formed and the composite sheet is integrally heat fused with the insert part. This method produces a foam base material product that is more durable and easier to assemble with an auto body than is the prior art.

Method for producing foam base material product with securing device

A method of molding soft sheet material having a foam layer and a skin layer. In the method, a skin powder is sprinkled on a predetermined area of the foam layer for forming the skin layer. The predetermined area is such that when the molded product is produced, the only waste material needing to be removed is foam layer. Therefore, the method enables recycling of the waste material and provides an increased yield.

Method for molding soft sheet material

A soft resin product is described, which comprises a resin main body and a soft resin covering part, wherein said resin main body comprises polyolefin and said soft resin covering part comprises a styrene based thermoplastic elastomer composition having a hardness H.sub.s of 20 to 50.

Resin product with main resin body and soft resin covering part

The present invention relates to a mold finished with decoration being soft to touch presenting velvety touch and lustrious appearance. Formed on the surface of a base portion is a soft intermediated layer for imparting a soft warm feel thereto. A multitude of piles are bonded thereto through an adhesive layer for imparting a soft feel to the soft intermediate layer, and a surface coating layer of polyurethane resin having fine foams therein is coated thereon. The mold of the present invention constructed as mentioned above presents velvety touch and lustrious appearance.
