    • Injection molding of a part having a nonuniform thickness is provided. One disclosed embodiment of an injection molding device includes one or more side walls, a first mold surface intersecting the side walls and being stationary with respect to the side walls, and a second mold surface intersecting the side walls so as to define with the side walls and the first mold surface a cavity configured to receive a metered amount of injected molten thermoplastic material. The second mold surface is moveable toward the first mold surface in such a manner that a first end of the second mold surface moves a larger physical travel distance toward the first mold surface than does a second end of the second mold surface during a molding process.
    • 提供具有不均匀厚度的部件的注射成型。 注射成型装置的一个公开的实施例包括一个或多个侧壁,与侧壁相交并且相对于侧壁静止的第一模具表面和与侧壁相交的第二模具表面,以便与侧壁 并且所述第一模具表面是被配置为接收计量量的注入的熔融热塑性材料的空腔。 第二模具表面可以朝着第一模具表面移动,使得第二模具表面的第一端在模制过程中比第二模具表面的第二端在第一模具表面移动更大的物理行进距离。
