摘要： PURPOSE:To suppress the reduction in the thickness of a deep drawing part by interposing an elastic material having proper elasticity with respect to the push-in surface of the push-in head provided to a mold on one side thereof in a protruding state, in forming the deep drawing part by pushing a part of a heat material softened under heating in the cavity of the mold formed on the opposite side thereof by the push-in head. CONSTITUTION:A sheet material 7 is softened by preheating prior to molding and applied to molds 1, 2 to clamp said molds. With the clamping of the molds, a push-in head 6 pushes the sheet material 7 in a recessed part 3. In this case, since the sheet material 7 is pushed in through an elastic material 8, the elastic material 8 generates shift deformation according to the tensile force acting on the sheet material 7 with pushing-in of said material 7. As a result, since the movement of the material quality of the sheet material 7 at the time of pushing-in is permitted, the thickness of a deep drawing part is made uniform.

摘要： PURPOSE:To simplify a fitting device and make joining properties high and intimacy between a molded substrate and decorating parts favorable, by a method wherein the fringe part of decorating parts are covered with the molded substrate in a state of an overhang and the rear of the decorating parts are joined by providing a joining device in a state of a coming-off stop. CONSTITUTION:Decorating parts 7 are fixed to a molded substrate 6 at the fringe part and rear, in a door trim 1. The outer skin 10 of pile cloth, a pad 9 and a core material 8 are laminated to the decorating parts 7 and a plurality of joining parts 11 are provided on the backside of the core material 8 in a protruding state. The decorating parts 7 are mounted on a protrusion 17 by turning the joining part 11 of the decorating parts 7 upside by projecting the fringe part of the decorating parts 7 evenly from the fringe of the top of the protrusion 17. A sheet base material 1 is heated by a top and bottom heaters 19, 19 and softened. Pinch pressing of a sheet base material 2 is performed in an airtight state between the fringe part of the bottom of an air-pressure box 20 and the fringe part of a molding tool 16, compressed air is sent into the air-pressure box 20 and air between the sheet base material 2 and a molding surface 18 of the molding tool 16 is discharged through suction. Hot forming is performed so that the sheet base material 2 is stuck close to the molding surface 18 and decorating parts 7 and made into a product of a trim board.

摘要： PURPOSE:To form a cured layer of a predetermined film only on the surface part of a molded body without allowing a coating solution to penetrate into the molded body by performing the curing treatment of the coating solution while the molded body coated with the coating solution is rotated. CONSTITUTION:In forming a cured layer 8 of a coating solution 7 to the surface part of a coating solution penetrable molded body 1 into which the coating solution penetrates, the molded body 1 coated with the coating solution 7 is rotated at a speed preventing the internal penetration of the coating solution 7 by a rotary means 3 and the curing treatment of the coating solution 7 is performed. As a result, the coating solution 7 does not penetrate into the molded body and the cured film of a predetermined film can be formed only on the surface part.

摘要： PURPOSE:To prevent the generation of heat or the increase of a spark by preventing the contraction of the interval between electrodes at the melting time of a material to be welded, by fixing a pair of electrode plates at the time of high frequency welding so that the interval between said electrode plates is kept constant. CONSTITUTION:A welding apparatus consists of a base part 1, a pair of electrode plates 2, 3 as a pair of electrodes for grasping a material 100 to be welded and a drive apparatus 4 for moving the electrode plate 2. When the material 100, is pressed by the piston 411 of a hydraulic cylinder 41, the thickness of the material 100 to be welded, that is, the interval (d) between the electrode plates 2, 3 is contracted. The piston 411 is fixed after pressurization is performed and a current is subsequently supplied between a pair of the electrode plates 2, 3 from a high frequency power supply. The supply of a current is stopped and the material 100 to be welded is again pressed by the piston 411. As a result, the electrode plates 2, 3 grasp the material 100 to be welded under pressure and the thickness of the material 100 to be welded, that is, the interval (d) between the electrode plates 2, 3 is contracted.

摘要： PURPOSE:To obtain the titled flexible and lightweight sheet, by using a thermoplastic sheet as a surface skin layer, laminating the thermoplastic sheet through a specific adhesive to a lower sheet of crosslinked expanded vinyl chloride resin to form a laminated foam and bonding long hair pile fabric to the undersurface of the foam by high-frequency adhesion processing. CONSTITUTION:A thermoplastic synthetic resin sheet (e.g. vinyl chloride resin) as a surface skin layer is laminated through an adhesive layer (10-150mu thickness) of plastisol or organosol coating compound of polyvinyl chloride resin to a lower layer of a crosslinked expanded vinyl chloride resin sheet having 5-60% crosslinking degree, 3-30 times expansion ratio and 0.5-5mm thickness and integrated to give a laminated foam. Then the foam is molded and formed. Long hair pile fabric or woven and knitted goods comprising a fibrous material of polyester resin, etc., are bonded to the undersurface of the formed laminated foam by high-frequency fusion processing while edge parts thereof. The composite sheet is flexible and lightweight, provided with steric design and fashion and suitable as an interior automotive trim.

摘要： PURPOSE:To enhance finish though the number of treatment processes are reduced, by forming a flat surface and an embossed pattern to a surface to be painted by paint containing a metal foil and applying clear paint thereon. CONSTITUTION:Metallic paint is applied to the surface 1 to be painted of a car body and dried to form a flat paint film 2. This metallic paint contains colored pigment and a fine fragmentary metal foil 3 with an outer diameter of 10mum or less comprising aluminum as paint components. Subsequently, an embossed pattern 4 is formed on the paint film 2 by the same metallic paint and, after drying, clear paint with high transparency containing no metal foil or pigment is applied to the embossing part 4A of the embossed pattern 4 and the exposed surface of the flat paint film 2 to form a clear film 5. After three- time painting is finished, the painting surface is once subjected to baking treatment to form a silver metallic color painting part 6.
