    摘要： The present invention provides thin injection molded plastic articles with an attractive, surface area of at least two different materials, such as leather, fabric, wood, metal or other semi-rigid surface material. These molded articles have desired combinations of thin dimensions, aesthetics and/or durability with the true feel of the real materials. The molded plastic articles thus have a plastic substrate component with a front decorative surface having at least two decorative surface areas of layers of different first and second materials having adjacent and connecting surface areas that are generally coplanar or continuous, including at the border line where the two surface layer materials meet. Relative to the front surface, at least a portion of the first material is located on top of and overlaps at least a portion of the second. In the process embodiment two surface material pieces are located in a mold cavity, the two materials together being located so as to each provide a surface area on the front side of the molded part. Optionally there is an adhesive and/or backing material on the back or non-decorative side of one or both surface material pieces. A molding plastic is injected into the mold that contacts and adheres to the back side of the surface material(s) and provides a molded on plastic substrate component. While the molding plastic is sufficiently fluid, pressure is applied to the cavity, preferably in an injection molding process, sufficient to compress and/or form the two different surface materials into a substantially coplanar or continuous surface and press the thicker overlapped area to a necessary depth into the plastic substrate component.

    摘要翻译： 本发明提供具有至少两种不同材料（例如皮革，织物，木材，金属或其他半刚性表面材料）的有吸引力的表面积的薄注射成型塑料制品。 这些模制品具有薄的尺寸，美观性和/或耐用性与真实材料的真实感觉的期望组合。 因此，模制的塑料制品具有塑料基材组分，其具有前装饰表面，其具有不同的第一和第二材料的至少两个具有相邻和连接表面区域的装饰表面区域，所述第一和第二材料具有大致共面或连续的相邻和连接的表面区域， 两层表层材料相遇。 相对于前表面，第一材料的至少一部分位于第二材料的至少一部分的顶部并且与第二材料的至少一部分重叠。 在该方法实施例中，两个表面材料片位于模具腔中，两个材料一起定位，以便在模制部件的前侧上提供一个表面区域。 任选地，在一个或两个表面材料片的背面或非装饰侧上存在粘合剂和/或背衬材料。 将模制塑料注入到模具中，该模具接触并粘附到表面材料的背面，并且在塑料衬底部件上提供模塑。 当成型塑料充分流体时，压力施加到空腔，优选地在注射成型工艺中，足以将两种不同的表面材料压缩和/或形成为基本上共面或连续的表面，并将较厚的重叠区域按压到必要的 深入塑料基板部件。
