摘要： The present invention relates to an apparatus/method for making a joint line in a plastic article comprising the steps of providing a mold having a mold surface, providing a gasket in the mold wherein the gasket defines first and second mold spaces, and molding a layer of a plastic material within one of the mold first and second mold spaces. In addition, during molding, the gasket is laterally moved relative to the mold surface in a direction towards that mold space containing the plastic material to therein form a distinct joint line. In alternative embodiment, a method is disclosed herein for making a molded two-colored article comprising the steps of providing a mold having a mold surface, providing a gasket in the mold wherein the gasket defines first and second mold spaces, followed by the molding a layer of a first colored material within one of the mold first and second mold spaces, wherein the first colored material comprises a charge of plastic microspheres having an outside diameter in the range of 0.007″ to 0.040″, and removing the gasket and molding a layer of a second colored material.
摘要翻译：本发明涉及一种用于在塑料制品中制造接合线的装置/方法，包括以下步骤：提供具有模具表面的模具，在模具中提供垫圈，其中垫圈限定第一和第二模具空间，以及模制层在模具第一和第二模具空间之一内的塑料材料。此外，在模制期间，垫圈相对于模具表面沿着包含塑料材料的模具空间的方向横向移动，从而形成不同的接合线。在替代实施例中，本文公开了一种用于制造模制的双色制品的方法，包括以下步骤：提供具有模具表面的模具，在模具中提供垫圈，其中垫圈限定第一和第二模具空间，随后模制在第一和第二模具空间之一内的第一着色材料层，其中第一着色材料包括具有在0.007“至0.040”范围内的外径的塑料微球的电荷，并且去除垫圈和模制一层第二有色材料。

摘要： A cover for an inflatable air bag housing is formed of integrally molded resinous plastic material and defined therein is a hinge area and a thin fracture line forming a door which pivots to an open position upon fracture of the cover along the fracture line when an air bag is inflated. A metal reinforcing element is embedded in the resinous plastic material and includes segments diverging and below the hinge area forming an open space or void which is filled in with a low density collapsible, energy absorbing, rigid foam which exhibits minimal spring back. The filler helps prevent sagging or read-through of the cover above the void when prolonged exposure to heat and sun is experienced. Moreover, the foam filler absorbs energy during bag deployment and aids in preventing plastic resin from leaking into the void space during the initial fabrication of the cover as the metal reinforcement element is molded in place.
摘要翻译：用于可充气气囊壳体的盖由一体模制的树脂塑料材料形成，并且其中限定有铰链区域和薄的断裂线，其形成门，当气囊在气囊充气金属增强元件嵌入在树脂塑料材料中，并且包括在铰链区域的下方和下方形成的开口空间或空隙的段，其填充有表现出最小回弹的低密度可收缩，能量吸收的刚性泡沫。当长时间暴露于热和阳光下时，填料有助于防止在空隙上方的凹陷的下垂或透视。此外，泡沫填料在袋展开期间吸收能量，并且有助于在金属加固元件被模制就位时在盖的初始制造期间防止塑料树脂泄漏到空隙空间中。
