  • Patent number: 6558146
    Abstract: According to the present invention, an in-line compounding and extrusion deposition compression molding apparatus and method for producing a fiber-reinforced molded structural component is provided. The apparatus comprises an extruder device having an internal cavity formed therein and an extruder screw rotatably disposed within the internal cavity for producing a polymer melt. A deposition die head is disposed at a first end of the device, the deposition die head having a die channel disposed therein for receiving the polymer melt from the device. The apparatus includes at least one fiber element for feeding at least one reinforcing fiber element into the die channel for compounding the at least one reinforcing fiber element with the polymer melt to produce a fiber-reinforced polymer compound. The apparatus additionally includes a mold for receiving the fiber-reinforced polymer compound to form the fiber-reinforced molded structural component.

  • Publication number: 20030038402
    Abstract: A method of making a panel by depositing a first extrudate into a mold cavity and pressing the first extrudate with a mold core to form a skin layer. The skin layer is cooled inside the mold cavity. A core material is loaded in the mold cavity onto the skin layer. A second extrudate is deposited into the mold cavity and onto the core. The second extrudate forms a structure layer. The mold core is pressed against the structure layer so that the structure layer forms around the core. The pressure of the mold core against the structure layer also presses the core into the skin layer. The structure layer and the skin layer cool while the mold core is pressed against the structure layer and the core material and the skin layer to form a panel. The panel is removed from the mold cavity.

  • Publication number: 20010048181
    Abstract: An apparatus having a single screw extruder and a twin screw extruder. The extruders are designed to operate intermittently in a batch-type process. The single screw extruder contains a plurality of barrel segments with an internal cavity, an inlet and a transfer die located at an outlet. The barrel segments provide processing flexibility in that the L/D ratio of the single screw extruder can be varied to accommodate various materials, fillers and material throughputs. The twin screw extruder includes a body having an internal cavity disposed therein. The body includes an inlet at a first end, an outlet at a second end and an inlet located along the length of the twin screw extruder to accept fiber material (fibers) from a side stuffer. A transfer valve is connected to the outlet of the twin screw extruder. The transfer valve controls the flow of melt from the twin screw extruder into an injection plunger.

  • Patent number: 6212851
    Abstract: A molded inner door panel for an automotive vehicle having a header extending above a beltline. The inner door panel has a notched metal frame insert, and a polymeric molded frame encasing the metal frame insert within the header. Advantageously, the notches provide precise inboard and outboard adjustability of the header of the inner door panel during assembly to the vehicle. The molded inner door panel has a resilient insert, e.g., elastomeric thermoplastic, disposed between the notches of the metal frame insert and the polymeric molded frame. Additionally, the polymeric material of the polymeric molded frame is substantially thinner in the area covering the notches than in the area bordering the notches. These features prevent the polymeric material from cracking upon adjustment.

  • Patent number: 6093272
    Abstract: A mold is provided having the shape of the trim panel and having a blade projecting from the mold at the juncture between the first and second regions to be covered by the different sheet materials. A first sheet material is provided and cut to fit the first region and also extend over the blade. This first sheet is draped over the mold and the blade. A second sheet material is bonded to a rigid substrate material, with the rigid substrate material having a flange structure along the edge margin thereof which is adapted to snap-fit over the blade of the mold and thereby hold in place the first sheet material which had previously been draped over the blade. The mold is then closed and a suitable molding material is injected to adhere to the back side of the first sheet material and the substrate layer of the second sheet material to thereby form the rigid trim panel. The mold is opened and the rigid trim panel is removed from the blade.
