    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： A process for producing a fiber-reinforced thermoplastic resin molded article including: (a) projecting a sheet-holding member from a cavity face of a lower mold towards a cavity face of an upper mold, (b) placing a heated fiber-reinforced thermoplastic resin sheet on the sheet-holding member, (c) closing the upper and lower molds, (d) in the step of closing the upper and lower molds, putting the sheet-holding member into the lower mold before the cavity face of the upper mold contacts with the resin sheet, (e) maintaining the upper and lower molds in a closed state, and (f) opening the upper and lower molds and removing the molded article. A fiber-reinforced thermoplastic resin molded article which has a good surface appearance and, if any, whose protrusions such as ribs and bosses are sufficiently filled with thermoplastic resin and reinforcing fibers, can be produced, without using an additional thermoplastic resin sheet and without repeating the molding process.

    摘要： A thermoplastic resin is molded by a press-molding method wherein a thermoplastic resin in a molten state is compressed to flow between a pair of female and male molds so as to be formed into a predetermined shape. A compression rate of the mold is controlled so that the following expression (1) is satisfied:0.5.ltoreq.B/A.ltoreq.2 (1)wherein A (mm/s.sup.2) is an acceleration which is realized at a time when the compression rate is 75% of a maximum rate in a compression-acceleration region, which region is defined as a period of time from a moment when the compression of the molten thermoplastic resin is started to a moment when the compression rate reaches the maximum rate; and B (mm/s.sup.2) is a deceleration which is realized at a time when the compression rate is 75% of the maximum rate in a compression-deceleration region, which region is defined as a period of time from a moment when the compression rate reaches the maximum rate to a moment when the closing of the molds is complete. By this method, a molded article having excellent surface appearance free from unevenness of gloss and surface irregularity can be obtained.
