    摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a resin molded article capable of safely and effectively imparting desired conductivity in a simple way.
    SOLUTION: A low melting point metal and a resin having a hardening temperature lower than the solidifying point of the low melting point metal are kneaded in a molten state, injecting the kneaded material into a mold set to a temperature lower than the solidifying point of the low melting point metal and higher than the hardening point of the resin. This construction enables a low melting point metal coating to be formed on the resin surface.

    摘要： PURPOSE:To obtain the titled molded piece with a high shielding effect to electromagnetic waves by a method wherein the surface of a mold is made up of fine ceramics different in thermal conductivity from the base material of the mold and the variety, the constitution, the thickness, the configuration and the distribution thereof are changed to control electric conductivity of the surface of the molded piece. CONSTITUTION:Fine ceramics 6, 7 of one kind at least that differs in thermal conductivity from mold base material are interposed on the entire or partial portion of a surface through which the mold 1 and plastic material are in contact with each other or the partial portion of a mold is replaced by fine ceramics of one kind at least that differs in thermal conductivity from the base material of the mold to constitute the entire or partial portion of the surface through which the mold surface comes in contact with plastic material. Besides, variety, constitution, thickness, configuration and distribution are changed in said fine ceramics interposed or replaced and plastic material is injected into the molding clearance 4 through a sprue 5 to obtain the desired molded piece with a non-electrically-conductive portion 10 and an electrically-conductive portion 11.

    摘要： PROBLEM TO BE SOLVED: To keep a bright feeling and make a weld line thin and non-conspicuous by relieving the disorder of orientation of a bright material in an injection mold in whose cavity a molten resin joins.SOLUTION: The cavity 3 of the injection mold is annular in a plane view, and has a rectangular cross section having an upper surface 3a constituting a design surface of an injection molded article, both the side surfaces 3b and 3b each connecting with the upper surface 3a, and a bottom surface 3c. When the molten resin is injected from a side gate 4, the mutually reverse flows are generated in the cavity 3. The molten resin joins at the position opposite to the side gate 4 in a radial direction of the cavity 3, and a part of the molten resin flows in the resin pools 5 and 5 arranged on both sides at the position. Since the flows horizontal to the upper surface 3a are thus generated, the bright material 7 is oriented approximately parallel to the design surface in the flow to relieve the disorder of the orientation of the bright material 7.

    摘要： PURPOSE:To manufacture conductive plastics including a fibrous metal and having no jamming of an electromagnetic wave, by dispersing a microcapsule to be obtained by covering a fibrous shape memory alloy deformed into a coillike state with resin is kept dispersed in a cavity. CONSTITUTION:A fibrous shape memory alloy, which has been deformed into a coillike state by applying external force to the same, is made into a microcapsule 6 having appropriate density by covering the alloy with resin, dispersed in the inside of a cavity 5 of a reactive injection mold and both solutions of a polyol stock solution and an isocyanate stock solution are injected from a mixing head 1, which are mixed and solidified. Simultaneously with softening of the resin of the capsule due to heat of reaction the shape memory alloy is extended and a conductive molded article including metallic fiber and having no jamming of an electromagnetic wave is obtained. It is possible to increase the metallic fiber in either a skin layer or a medium layer by making use of a floating or a sinking phenomenon due to density difference among the capsules. There is no abrasion on a kneading screw.
