    摘要: The invention relates to a method for producing a composite component, wherein a hollow profiled element (16) is expanded at least in some areas by internal high pressure, wherein in a first step, an area of the hollow profiled element (16) is expanded until the area comes in contact with an edge area (28) of a cavity (18) of a combined internal high-pressure forming and injection molding tool, and in a second step, the cavity (18) is filled with an injection molding mass, wherein in a third step, the hollow profiled element (16) is further expanded at least in some areas by increasing the internal high pressure.

    摘要: An object of the present invention is to obtain a composite in which a copper or copper alloy is securely integrated with and joined to PBT or PPS. A copper product that has been suitably roughened by chemical etching and also blackened can be used favorably. A surface-treated copper piece 1 is inserted into a cavity formed by a movable molding plate 2 and a stationary molding plate 3 of an injection molding mold 10, and a specific resin is injected to obtain an integrated product. PBT or PPS can be used as the resin component of a resin composition 4 that is used here. High injection joining strength is obtained if the resin composition contains, as an auxiliary component, PET and/or a polyolefin resin in the case of PBT, and a polyolefin resin in the case of PPS.

    摘要: A slide core (12) is provided with a first core section (13) increasingly inclined in a drafting direction and a second core section (14) decreasingly inclined in the drafting direction. Thus, even when the slide core (12) itself has no draft angle, the first core section (13) is firstly drafted to cause a clearance (D) to an inner surface of a hollow space (10) of a tubular resin member (3). Thereafter, the entire slide core (12) can be easily drafted together with the second core section (14). Since the slide core (12) does not require a draft angle as in the conventional design, the manufactured tubular resin member (3) has a uniform thickness. The first core section (13) and the second core section (14) are engaged at a T-shaped slot (16) and a T-shaped groove (17). Thus, the first core section (13) can be slid in a drafting direction S2 to allow only the first core section (13) to be firstly slid to subsequently allow the second core section (14) to be slid to follow the sliding movement of the first core section (13).
