An automobile decoration molding includes a decoration molding body formed by extrusion-molding a synthetic resin material; and an end part formed by remolding the end portion of the decoration molding body with a die. At least the end portion of the decoration molding body which is to be formed into the end part is formed by using the synthetic resin material kneaded with electrically conductive metallic powder, and the end portion of the decoration molding body which is to be formed into the end part is obliquely cut in such a manner that the resultant cut becomes larger in the direction opposite to a decorative surface of the decoration molding body, and the end portion thus processed is remolded with a die consisting of an upper half die and a lower half die.

In a two layer extrusion molding, a core part 11 is formed of hard resin material, a crease pattern 11a having a given depth, preferably, a depth in the range of 10 to 20 .mu.m is formed on the surface of the core part 11, and a skin part 12 formed of soft resin material is coated on the surface of the core part 11. Thus, the core part and skin part are effectively prevented from being detached from each other to thereby improving the quality of the molded product.

Two layer extrusion molding

A method of terminal treatment for an extrusion molding of the present invention including the steps of: applying double-sided adhesive tape to necessary positions of an extrusion molding; cutting the extrusion molding with the double-sided adhesive tape stuck thereon into a necessary length; cutting a release paper of the double-sided adhesive tape into a predetermined length less than the necessary length of the extrusion; and forming a terminal of the extrusion into a predetermined form by injection molding.

Terminal-treated extrusion and the method of terminal treatment therefor

A molding is disclosed which is constituted by a main molding body formed in an elongated plate-like shape made of soft resin and having a fitting hole passing therethrough in the thickness direction thereof. The molding further has a retainer which is inserted into the fitting hole from the reverse side of the main molding body and a fitting part made of a hard resin which is inserted into the fitting hole from the obverse side of the main molding body, wherein the fitting part is mechanically secured to the retainer to allow the fitting part to be secured to the main molding body. The fitting part has a first seating surface which abuts against the obverse side of the main molding body, and the retainer has a second seating surface which abuts against the reverse side of the main molding body, wherein the main molding body is held and pressed between the first seating surface and the second seating surface.

Molding with fitting and retainer means

An extruding method for manufacturing an elongate strip partially having at least one cross-sectional T-shaped part composed of a head section and a leg section, which comprises extruding a material, partitioning the head section and the leg section in the vicinity of the exit end of the die, uniting the head section and the leg section naturally and solidifying the extruded strip. Hereby, recesses undesirably formed on the surface corresponding to the junction of the head section and the leg section composing the cross-sectional T-shaped part of the elongate strip when using methods heretofore known, can be prevented.
