본 발명은 자동차용 라디에이터 그릴 제조방법에 관한 것으로, 더욱 상세하게는 정해진 특정 부위에 금속성 광택감을 부여하기 위하여 상기 특정 부위에만 메탈필름을 부분적으로 인서트시키는 필름 인서트 몰딩(Film Insert Molding) 방식으로 내후성이 우수한 ASA 수지(Acrylonitrile Styrene Acrylate)를 사출성형하여 제조한 라디에이터 그릴 제조방법에 관한 것이다. 본 발명의 라디에이터 그릴 제조방법에 따르면, 불필요한 부위까지 적용되었던 도금공정을 생략할 수 있으므로 원가를 절감할 수 있고, 공정의 단순화로 공정주기를 단축시킬 수 있어 생산성을 향상시킬 수 있는 효과가 있다. 그리고, 기존의 ABS 수지(Acrylonitrile Butadiene Styrene) 대신에 내후성이 우수한 ASA 수지를 사용하여 성형하는 동시에 수지 표면을 엠보싱 처리하여 제조하므로 종래의 흑색도장공정을 생략할 수 있는 장점이 있다.
Abstract:
PURPOSE: An intake system of an engine is provided to enhance durability since an inter lever is relatively free from external interference due to a structure of directly connecting the middle parts of first and second shafts, which are adjacent. CONSTITUTION: An intake system of an engine comprises first and second intake paths, a first shaft(120a), a second shaft(120b), a first flap(130a), a second flap(130b), an inter lever(140) and a driving unit(100). The first and second intake paths are arranged side by side. The first and second shafts are arranged side by side along the first and second intake paths. The first and second flaps are respectively mounted on the first and second to open/close the first and second intake paths. One end of the inter lever is connected to the first shaft and the other end of the inter lever is connected to the second shaft. The rotation of the first shaft is delivered to the second shaft. The driving unit rotates the first shaft so that the first and second flaps make the first and second intake paths open/close.
Abstract:
PURPOSE: A back beam for a rear bumper for a vehicle is provided to enable the rear bumper to be efficiently manufactured since a vehicle-body mount is formed integrally with the back beam. CONSTITUTION: A back beam for a rear bumper for a vehicle consists of a body(10). One or more vehicle-body mounts(11) are formed integrally with both ends of the body. The vehicle-body mount is protruded from the rear to the front of a vehicle body. The body has a C-shaped section. The body is formed from a pellet type of polyprophyelene material including long glass fibers.
Abstract:
A soft thermoplastic resin composition is provided to lower the coefficient of linear thermal expansion and the specific gravity and to improve impact resistance. A soft thermoplastic resin composition comprises 5-50 wt% of at least one kind of olefin-based thermoplastic elastomer selected from the group consisting of a partially crosslinked olefin-based thermoplastic elastomer and a totally crosslinked olefin-based thermoplastic elastomer; 1-40 wt% of an alpha-olefin-based copolymer rubber, an olefin-based copolymer rubber or a styrene-based copolymer rubber; 30-60 wt% of a polypropylene rubber having a melt index of 60-90 g/10 min; and 10-30 wt% of an inorganic filler having an average diameter of 0.1-15 micrometers.
Abstract:
PURPOSE: A separating panel made of a conductive polymer or a carbon complex for a polymer electrolyte fuel cell is provided to achieve a light weight and a thin thickness, prevent corrosion, and reduce production cost owing to the simplified process, compared to the conventional separating panel. CONSTITUTION: The separating panel(1) for a polymer electrolyte fuel cell is mainly comprised of a conductive polymer or a carbon complex, wherein the conductive polymer is at least one selected from a group consisting of polyaniline, polyphenylene, polythienylene vinylene, polypyrrole, polyphenylene vinylene and polyacetylene, and the carbon complex is one added with at least one selected from a group consisting of phenol resin, vinyl ester resin, epoxy resin, reinforced polyester resin and polyimide resin. The separating panel is produced by (a) preparing a mesh type gas flow channel panel(10) and a collecting panel, wherein the separating panel is a serpentine-parallel type panel having a gas channel or a mesh type gas separating panel; (b) attaching a gasket to meshes except the meshes contacting with the electrode in the mesh type gas flow channel panel; and (c) attaching the collecting panel to the mesh type gas flow channel panel from the step (b).
