In accordance with the present invention, a preferred embodiment of a method for manufacturing a trim panel assembly is provided. A further aspect of the invention provides a method that includes a first tool having a mold element movable between a first position and a second position, the first tool producing a trim panel having a recess when the element is in the first position. A bolster, manufactured using a second tool, is secured within the recess.

An object is to provide a method for manufacturing a resin laminate IOU, the method being capable of achieving satisfactory reduction in weight and wall thickness while ensuring manufacture efficiency and product quality. To accomplish the object, a resin laminate manufacturing method includes a step of providing a pair of split mold blocks one of which has a cavity provided with a plurality of protrusions each extending toward the other one, and preparing two molten thermoplastic resin sheets each having a thickness adjusted, a step of feeding the two molten thermoplastic resin sheets between the pair of split mold blocks with a predetermined gap left therebetween such that each thermoplastic resin sheet protrudes around annular pinch-off parts, a step of forming a hermetic space between one of the sheets and the cavity of the one mold block opposed to an outer surface of the one sheet, a step of sucking air in the hermetic space from the one mold block side, pressing the outer surface of the one sheet against the cavity of the one mold block to shape the one sheet, and forming cup-shaped portions, and a step of clamping the pair of mold blocks, welding peripheral edges of the two molten thermoplastic resin sheets to each other, and welding the bottoms of the cup-shaped portions formed on the one sheet to an inner surface of the other sheet. According to this method, in the resin laminate thus manufactured, the two sheets are substantially equal in thickness to each other.

The invention discloses a car spare tire cover plate manufacturing method which comprises the following steps: delivering PP (polypropylene) engineering plastic particles into a charging barrel above a blow molding machine; heating and delivering the plastic particles to an extrusion die head by virtue of an extrusion screw rod; fixing a punched non-woven fabric on the fixed die cavity plate of a blow molding die; extruding molten plastic from the die head through the extrusion die head, thus forming a primary blank; sealing the lower end of the primary blank through a sealing device, starting the die head for blowing, thus forming the blank with needed dimension through blowing expansion, and starting die assembly; when the die assembly is in place, starting an oil cylinder on a supporting plate instantaneously so as to push a reinforcing rib forming push plate on a fixing plate to extrude the blank, delaying for 1-2 seconds, retreating the oil cylinder, and simultaneously starting a blowing needle for blowing; carrying out blowing forming and cooling; and carrying out die sinking when preset forming and cooling time is achieved, and taking out the finished product The spare tire cover plate manufactured by the method is light in mass, good in sound-insulating effect, large in bearing force and good in attaching effect of the body and the fabric

A disclosed process includes steps of heating a foamed material by irradiation with near infrared radiation having a wavelength between 0.78 and 1.40 μm to form a heated material, forming the heated material with a forming tool to obtain a formed material, and cooling the formed material and demolding to obtain a final workpiece. The foamed material may be constructed as a composite ply construction including an outer material and a foamed core between the outer material. The foamed material may contain a poly(meth)acrylimde, a polypropylene or a highly-crosslinked polyurethane.

A method for molding panels (44) in a sheet molding system comprised of a thermoplastic sheet delivery station (10) and two mold halves (18), the method comprising the steps of delivering two sheeting layers (12, 14) of thermoplastic material between the two mold halves; inserting a regidizing insert (40) between the two sheeting layers of thermoplastic material; closing the mold halves to bring the two sheeting layers of thermoplastic material in contact with the insert; and compressing the thermoplastic sandwich between the mold halves to form a panel. A thermoplastic-insert sandwich and a laminate panel comprised of thermoplastic layers abutting a pre-manufactured insert are also claimed.
