    与其姊妹公司AF-COLOR合作支援内层包覆射出成型 技术(InCoat Process),以单一加工成型步骤成功生产 一个内层包覆PU的低吸湿PA6+20%玻璃纤维材质的 引擎盖。这个称为内层包覆射出成型(InCoat Process) 的创新技术结合了热可塑性塑料的射出成型与PU的反 应射出成型 (Reaction Injection Molding,简称 RIM), 其中的关键是所使用的PA原料必须与PU产生好的黏 著性。为了实现这个目的,安科罗工程塑料公司提供了 AKROMID® B3 GF 20 2 RM-D natural,而AF-COLOR 则开发了适合这个规格适用的绿色色母。 AKRO-PLASTIC and its sister company AFCOLOR supported the InCoat process in which a demonstration engine cover part was overflooded with a PU layer in a single process step. Here one of the prerequisites was a material to which PU would have a good bonding. AKRO PLASTIC supported with the material AKROMID® B3 GF 20 2 RM-D natural (4164) and AF-COLOR developed a green colour masterbatch AF-Color® PA 601292 green suitable for this grade.

    目前的汽车用内装设计的趋势已经转为特別要求轻量化 与高品质的表面特性,这是符合经济与大量生产的解决方案。
    The trend towards light and high-quality surfaces, which are particularly in demand in the automotive industry for the design of vehicle interiors, is fueling the demand for economical and mass-produced solutions.

    这些典型的汽车用内装应用包含仪表板,汽车门板, 柱饰与其他装饰部件,借着合并PA复合材料与PU 材料的成型,高附加价值的部件可以有效的被大量生 产.因此这项新技术不只可以使用于汽车内装应用也 可使用于汽车外装应用,更可以扩展於其他需要这项 特殊成型方式的工业产品。
    Typical applications in automotive interior are instrument panels, door panels, pillar trims and other trim components. By combining injection molding with the PU process, higher-value components can be effectively produced in large quantities. This makes this technology interesting not only for a variety of applications in the automotive interior, but also in the automotive exteriors. This solution could also be interesting for other industries where injection moulded parts have a much broader application.■
