Process for producing a multilayer molded article
TL;DR: In this article, the authors present a process for producing a multilayer molded article which includes supplying at least one piece of a skin material having a desired shape and a resin melt between unclosed upper and lower molds and closing the molds to form a multi-layer molded article including the thermoplastic resin and the skin material which covers only a desired part of the article.
Patent
Process for producing multilayer molded article
TL;DR: In this article, a method for producing a multilayer molded article in which an skin material having nap on the outer surface thereof is integrally molded with a substrate of a synthetic resin, using a mold comprising a pair of male and female mold halves.
Patent
Method for producing molded article of fiber-reinforced thermoplastic resin
TL;DR: In this article, a method for producing a molded article of a fiber-reinforced thermoplastic resin, which comprises supplying a melt mass of a thermoplastastic resin (A) which is reinforced with fibers dispersed therein and having an average fiber length of not shorter than 1 mm and not longer than 50 mm as a reinforcing material in an unclosed mold, is described.
Patent
Screw apparatus and method for supplying reinforcing fiber-containing molten resin using the apparatus
TL;DR: A screw unit as discussed by the authors consists of a melting extruder for melting a resin; a screw unit for kneading molten resin and reinforcing fibers to obtain a reinforcing fiber-containing molten resins and supplying it; and a mixer in which at least a part of the reinforcing fibers attach to the molten resin which is extruded from the melting extruders and flows down owing to gravity in an open space.
Patent
Method for producing polypropylene resin article having skin material lined with foamed layer
TL;DR: In this article, a multi-layer polypropylene body and a skin material with a foamed layer is used to produce a good appearance and is produced using upper and lower molds which have a cavity there between.
