Abstract In this study, a modified T-shape extension nozzle (TsEN) with a high temperature (HT) ultrasonic transducer (UT) rod connected to its barrel and mold to carry out the injection molding (IM) process diagnosis is used. Two integrated HTUTs were fabricated on both sides of a rod for monitoring IM process at elevated temperatures real-time, non-intrusively as well as non-destructively. Two plastics, polypropylene (PP) and acrylonitrile–butadiene–styrene (ABS), were employed to demonstrate the effects of various operation settings and materials on the molded sample quality. Based on the provided information, an innovative way of controlling the supply to structure process in regards to the plastic from the barrel into the nozzle, mold and the final product during the IM process is presented. Each phase of the process, including closing mold, injecting material, packing, and feeding material can be analyzed by an ultrasonic waveform during the various settings of the IM process of PP and ABS plastics. The various injection speeds of the PP and ABS plastics cause different deflection performance of the molded samples. This phenomenon can be observed by measuring the ultrasonic velocity at the beginning stage of molding. Therefore, a modified TsEN with an HTUT rod could provide a rigid structure and an innovative solution for how to run continual diagnosis during the IM process to verify the dynamics of process and analyze the flow rate and the state of the molten plastic to ensure better product quality.

T型加长喷嘴超声技术诊断多段注塑成型工艺

摘要 在这项研究中，使用一种改进的 T 形延长喷嘴 (TsEN)，其高温 (HT) 超声换能器 (UT) 杆连接到其机筒和模具，以进行注塑 (IM) 过程诊断。在棒的两侧制造了两个集成的 HTUT，用于实时、非侵入性和非破坏性地监测高温下的 IM 过程。两种塑料，聚丙烯 (PP) 和丙烯腈-丁二烯-苯乙烯 (ABS)，被用来证明各种操作设置和材料对模制样品质量的影响。根据所提供的信息，提出了一种在 IM 过程中控制塑料从桶到喷嘴、模具和最终产品的结构过程供应的创新方法。过程的每个阶段，包括合模，在PP和ABS塑料的IM工艺的各种设置过程中，可以通过超声波波形分析注射材料，包装和喂料。PP 和 ABS 塑料的不同注射速度导致成型样品的不同挠曲性能。这种现象可以通过在成型开始阶段测量超声波速度来观察。因此，带有 HTUT 杆的改进型 TsEN 可以为如何在 IM 过程中运行连续诊断以验证过程动力学和分析熔融塑料的流速和状态以确保更好的产品提供刚性结构和创新解决方案。质量。PP 和 ABS 塑料的不同注射速度导致成型样品的不同挠曲性能。这种现象可以通过在成型开始阶段测量超声波速度来观察。因此，带有 HTUT 杆的改进型 TsEN 可以为如何在 IM 过程中运行连续诊断以验证过程动力学和分析熔融塑料的流速和状态以确保更好的产品提供刚性结构和创新解决方案。质量。PP 和 ABS 塑料的不同注射速度导致成型样品的不同挠曲性能。这种现象可以通过在成型开始阶段测量超声波速度来观察。因此，带有 HTUT 杆的改进型 TsEN 可以为如何在 IM 过程中运行连续诊断以验证过程动力学和分析熔融塑料的流速和状态以确保更好的产品提供刚性结构和创新解决方案。质量。
