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.

The invention relates to a method for making an over-moulded part (10) that defines a structural part for an automobile, comprising: a moulding step during which at least one member (12) of the part (10) is moulded from a first material containing a heat-curable material, using a mould (24) shaped so that at least a portion of the member forms a material web (30); an over-moulding step during which a second material containing a heat-curable material is over-moulded on at least one of the material webs (34) of the member (12) so that the material web (34) is torn under the pressure (42) of the second material, a passage (35) for the second material being then formed through the member. The invention also relates to a structural part for an automobile.

The invention relates to a method for producing composite components (1) from a profile (2) and an injection moulded element (3), wherein the injection moulded element (3) is moulded onto the profile (2) such that the profile (2) is fully enclosed in the circumferential direction and at least one form enclosure element (7) is produced which is included. According to the invention, the injection moulded element (3) of the produced composite component (1) may be given a permanent hold on the profile (2), wherein the form enclosure element (7) lying between the ends (8,9) of the profile (2) has a limited shaping on the circumferential direction and the longitudinal direction.

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:
Es wird ein Verfahren zur Herstellung von Kunststoffspritz- oder -pressteilen, welche bei ihrem Formgebungsprozess mit einem oder mehreren metallischen Hohlprofilen (10) kombiniert werden, angegeben, bei dem in einem Spritz- bzw. Presswerkzeug für eine Aufnahme einer gespritzten oder gepressten Kunststoffmasse eine Kavität (24) ausgebildet ist, in die sich ein Anbindungsflansch (26) des metallischen Hohlprofils (10) erstreckt, wobei das oder jedes metallische Hohlprofil (10) durch Dichtflächen (28, 30) am Rande der Kavität (24) gegen die Press- bzw. Spritzkräfte der Kunststoffmasse (12) während des Formgebungsprozesses geschützt ist.

Die Erfindung betrifft eine Verwendung eines Laser-Durchstrahlschweiss-Verfahrens zum Herstellen eines Fahrzeug-Dachteils (12, 14) mit wenigstens zwei miteinander verbundenen Kunststoffschichten (32, 34). Die vorteilhafte Verwendung sieht vor, dass das Fahrzeug-Dachteil (12, 14) wenigstens eine erste obere transparente Kunststoffschicht (34) und eine zweite untere nicht transparente Kunststoffschicht (38) aufweist, die an ihrer Trennfläche (40) mittels eines Laserstrahls (52) eines oberhalb der ersten Kunststoffschicht (32) geführten Laserschweisskopfs (50) zumindest punktuell miteinander verbunden werden.
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).
摘要:
A reinforced structure of a metallic member is described, in which a metallic member having an opening on at least one face thereof is reinforced with a resin member, deformation of the opening being inhibited by reinforcing means of (1) closing the opening with the resin member to form a rectangular closed cross-section, or (2) providing a reinforcing rib as a resin member in the inside of the opening and fixing a joint section integrally molded with the rib to the metallic member by a channel provided in the joint section or through engagement.
