摘要： A process for producing a skin material-laminated hollow molded article of thermoplastic resin, using a mold having, in any one or both of its fixed and movable parts, at least one fluid-ejecting pin which can be slid in a clamping direction and which has a fluid-ejecting hole at its pointed end. The process consists of fixing two sheets of a skin material having a tensile modulus at ambient temperature of 50-1,000 kg/cm.sup.2 and a tensile modulus at 80.degree. C. of 5 to 100 kg/cm.sup.2 on the parting surfaces of both the mold parts which are in the open state. A molten thermoplastic resin is fed between the skin materials in an amount of 5 to 50% by volume of the cavity volume. The fluid-ejecting pin is thrusted so that its pointed end penetrates one of the skin material sheets and comes between the skin material sheets. The mold parts are closed to wrap the molten thermoplastic resin in between the skin material sheets. A fluid is ejected from the fluid-ejecting hole to intimately contact the skin material sheets with the cavity surface of the mold while allowing the molten resin to form a hollow. The mold is cooled and the ejection of the fluid is stopped. The mold is then opened and the hollow molded article is removed.

摘要： There is provided a process for producing a multi-layer molded product having a plurality of thermoplastic resin layers. This process provides for (i) a step of supplying first and second molten thermoplastic resins each through first and second resin supplying gates which are temperature-controllable independently of each other, to between female and male molds kept in an open state with a time difference being provided between supply starts of the first and second resins, and (ii) a step of closing the female and male molds after completion of supply of the first and second resins. The process enables production of high-quality multi-layer molded products having a plurality of resin layers with good repeatability under relatively low resin supply pressure and by single mold closing. Further, high-quality multi-layer molded products can readily be produced without restrictions on materials used.
