摘要： PROBLEM TO BE SOLVED: To judge the depth of a bottomed groove by a simple method in a molding technique for molding matter made of a synthetic resin having the bottomed groove. SOLUTION: A pressure member 20 driven by a cylinder 28 is housed in the slide hole 16, which is provided on the fixed mold 12 of a mold 10, in a slidable manner, and a groove molding member 22, which is movable along the guide groove 141 bored in the fixed mold 12, and a moving member 24 movable along the communication hole 142 bored in the fixed mold 12 are erected on the pressure member 20. After a molten synthetic resin is sealed in a cavity 18, the groove molding member 22 is protruded into the synthetic resin by driving the cylinder 28 to form the bottomed groove 76 becoming a breaking part 74 and it is observed whether the projection formed by a moving member 24, of which the vertical part 242 is set so as to become flush with the inner surface 182 of the cavity 18 when the groove molding member 22 protrudes into the cavity 18 by normal dimension, is present in a groove depth confirming part 78 to judge the depth of the bottomed groove 76.

摘要： PROBLEM TO BE SOLVED: To manufacture an exterior panel for a vehicle by a reduced number of processes using an inexpensive mold. SOLUTION: Foam molding is performed between an exterior shaped sheet 5 and an interior shaped sheet 6 both of which are shaped into a predetermined design shape to form the foam 4 integrally bonded to the exterior shaped sheet 5 and the interior shaped sheet 6. An expensive mold used in injection molding or press molding heretofore is dispensed with and the cost required in a mold can be reduced. Since the exterior shaped sheet 5 and the interior shaped sheet 6 are integrated in the foam molding process, an assembling process requiring much manhour can be omitted.

摘要： PROBLEM TO BE SOLVED: To obtain the subject composition stably pelletizable and useful for producing favorably recyclable molded products by including specific carbonized polyacrylonitrile fiber piles and/or specific viscose rayon fiber piles. SOLUTION: This composition is obtained by including carbonized polyacrylonitrile fiber piles >=10 wt.% in nitrogen content and/or viscose rayon fiber piles pigmented with a pigment; wherein each of the fiber piles is pref. 1-15 denier in fineness and 0.1-2 mm in length. More precisely, this composition is obtained, preferably, by including 15-40 wt.% of polypropylene, 15-40 wt.% of polyethylene, 10-30 wt.% of an ethylene-propylene elastomer, 1-10 wt.% of an acid-modified polypropylene and 5-20 wt.% of fiber piles. A molded product obtained by blending the above composition with non-colored resin pellets followed by molding the blend is excellent in weatherability and good in both mechanical and thermal properties.

摘要： PROBLEM TO BE SOLVED: To advantageously reduce unevenness of color tones in the appearance by composing a resin molded article of a base material, composed essentially of a resin, and glossy micro-bodies which are mixed at least in the surface layer side of the base material so as to adjust the color tones of the surface layer of the base material, the glossy micro-bodies being composed of a plate- like object having a three-dimensionally curved part. SOLUTION: A resin molded article A comprises a base material 1 composed essentially of a polypropylene which is a light-transmitting resin, and a large number of glossy micro-bodies 3 mixed in the base material 1. Even when a weld part 100 is formed in the resin molded article A, it is possible to prevent generation of a large difference in orientations between glossy micro-bodies 3 (3A) in one weld part 101 and glossy micro-bodies 3 (3B) in the other weld part 102, both parts being adjacent to each other via the weld part 100 as the boundary. Thus, unevenness of metallic color tones in the appearance of the resin molded article having a weld part 100 as a boundary is advantageously reduced.
