摘要： A gas assisted injection molded part includes internal cavities extending between two surfaces of the part. The cavities are plated for electrical conductivity after a surface cleaning and etching process. The part may be an automobile instrument panel wherein the internal cavities are plated to create a series of "bus" conductor lines. These lines carry power, ground and/or electrical signals over relatively large distances, allowing other components to attach at points along the structure eliminating the need for discrete wiring and wire harness interconnect assemblies.

摘要： A method of manufacturing a film-covered article by the following steps. A thermoplastic film is heated to become pliable. The film has a decorative surface and a backing surface. The heated film is positioned between an open mold. The open mold has a first mold surface, a sealing surface and a sealing member. The sealing surface contacts the sealing member and forms a chamber between the mold and the film. A fluid pressure is applied between the mold and the film to cause the film to conform to the first mold surface. A molten resin is injected adjacent to the film-backing surface to form the film-covered article. The invention may be practiced by either applying a positive pressure to push the film to conform to the first mold surface or a negative pressure to drawing the film against a vacuum between the film and the first mold surface.
摘要翻译：一种通过以下步骤制造薄膜覆盖制品的方法。热塑性薄膜被加热变得柔软。该膜具有装饰表面和背衬表面。被加热的薄膜位于打开的模具之间。开模具有第一模具表面，密封表面和密封构件。密封表面接触密封件并在模具和膜之间形成一个室。在模具和膜之间施加流体压力以使膜符合第一模具表面。在薄膜背衬表面附近注入熔融树脂以形成薄膜覆盖的制品。本发明可以通过施加正压以推动膜以符合第一模具表面或负压以抵抗膜和第一模具表面之间的真空来实施。
