摘要： A simple and inexpensive method and apparatus for molding a peripheral frame around a sheet or grid of thermoplastic material to produce a framed panel. A peripheral frame, preferably of structural foam or the like, is injection molded about a thermoplastic sheet or grid of panel-forming material which has been previously drawn or stretched at a temperature which orients the molecules of the polymer, i.e., below the glass transition temperature of the polymer, T.sub.g. Either during the frame molding process, or subsequent thereto, the panel-forming material is heated sufficiently to cause the material to shrink or revert toward its prestretched condition so as to tension the panel-forming material within the frame. Elastomeric sealing means are disclosed for sealing the mold during injection of the frame-forming material and locator fingers are provided to position a grid-like panel-forming material prior to initiation of the molding process. By the utilization of structural foam molding techniques, a panel of thermoplastic material may be integrally-molded and tensioned within a rigid frame to produce a framed panel of any size for use as a barrier, a fence, a guard, a closure, a seat or bedding support, a filter member or other such applications.

摘要： A pad for an air bag device including an upper wall portion which has an openable portion which, upon expansion of the air bag, is separated from a side wall portion of the pad, leaving a hinge portion, and is angularly movable about that pivot axis so as to be openable. The openable portion is constituted by a net insert of a net-like configuration and a covering layer of a soft material covering the net insert. The net insert has a slit which is formed in one edge portion thereof remote from the hinge portion and extends toward the hinge portion. With this construction, even if part of the pad is curved, the net insert can be set in a corresponding injection mold without generating wrinkles in the net insert, and the molding can be performed in such a manner that the openable portion has a good appearance.

摘要： The invention is directed to a method of making fibrereinforced plastic moulded parts, in which fibrous material such as glass fibre material is placed in a mould and a liquid synthetic composition is pressed into the fibrous material with the aid of a pressure bag. In order to avoid air bubbles and defects not provided with synthetic composition, the invention provides for a wide-meshed net to be placed either onto or between the fibrous material. During pressing, this net will promote escape of the air entrapped in the fibrous material.

摘要： A method of making plastic screen where a plurality of pegs are vertically positioned within an open topped mold by passing a peg through each opening of a positioning screen member located above the mold, and a castable liquid plastic is then poured into the mold. The bottom ends of the pegs are tapered, so that the holes or openings in the finished plastic screen are flared. Metal reinforced plastic screen is made in the same manner, only a peg is positioned within each opening of a metal screen, whose openings are the same size as, and are in alignment with, the openings of the positioning screen member, the metal screen being positioned closely adjacent the mold bottom or base, and the liquid plastic is poured into the mold to a height above the metal screen. The pegs are smaller than the metal screen openings, so that no metal is exposed in the finished article.
