Abstract: A method of selecting thermoplastic materials for use with an injection molding apparatus that adjusts viscosity of a thermoplastic material based on an interpreted viscosity is provided. The method includes determining a target MFI for an identified plastic article based on performance properties. A thermoplastic material supply chain is analyzed and a first thermoplastic material having a first starting MFI and a first MFI range is identified and a second thermoplastic material having a second starting MFI and a second MFI range that is greater than the first MFI range is identified and is priced less than the first thermoplastic material. The second thermoplastic material is purchased. The second thermoplastic material is tested by providing the second thermoplastic material to the injection molding apparatus for multiple shot molding cycles with the second thermoplastic material in a molten state. The step of testing includes monitoring melt pressure of the molten second thermoplastic material using a sensor and providing a signal to a controller indicative of melt pressure. The controller controls introduction of an additive to the second thermoplastic material thereby changing a viscosity of the molten second thermoplastic material based on the signal. A molded article is formed by reducing a mold temperature of the second thermoplastic material within the at least one mold cavity.

Abstract translation: 提供了一种选择与用于调节基于解释粘度的热塑性材料的粘度的注塑设备一起使用的热塑性材料的方法。 该方法包括基于性能特性确定所识别的塑料制品的目标MFI。 分析热塑性材料供应链，并且识别具有第一起始MFI和第一MFI范围的第一热塑性材料，并且识别出具有大于第一MFI范围的第二起始MFI和第二MFI范围的第二热塑性材料， 的价格低于第一种热塑性材料。 购买第二种热塑性材料。 通过将第二热塑性材料提供给用于多次注射成型循环的注射成型设备，第二热塑性材料处于熔融状态来测试第二热塑性材料。 测试步骤包括使用传感器监测熔融的第二热塑性材料的熔体压力，并向指示熔体压力的控制器提供信号。 控制器控制向第二热塑性材料引入添加剂，从而基于该信号改变熔融的第二热塑性材料的粘度。 通过降低至少一个模腔内的第二热塑性材料的模具温度来形成模制品。
