综述了基于元模型的注塑成型工艺参数优化方法。PIM是生产轻质和高光泽外观塑料产品的典型制造技术。为了生产塑料产品，通常通过试错法来调节工艺参数，例如熔体温度、注射时间、填充压力、填充时间、冷却温度和冷却时间。计算机辅助工程（CAE）是PIM中的替代方法之一，但是数值模拟在计算上是如此昂贵，以至于基于元模型的优化被广泛用于确定最佳工艺参数。首先，包括抽样策略的典型元模型进行了简要回顾。然后，对提高产品质量的工艺参数优化，如翘曲，收缩和焊缝减少的文件进行了审查。主动控制模具温度的快速热循环成型（RHCM）是一种新型的粉末注射成型技术，但其工艺参数的优化研究很少。然后，本文还回顾了RHCM。无论是工艺参数的优化，还是冷却通道的优化，都对提高产品质量和生产效率起着重要的作用。由于金属3D打印机的最新进展，可以生产保形冷却通道。采用随形冷却通道可以提高产品质量和生产效率。同时也回顾了几篇关于采用共形冷却通道的工艺参数的论文。
This paper comprehensively reviews the process parameters optimization in plastic injection molding (PIM) using the metamodel-based optimization. The PIM is a typical manufacturing technology to produce lightweight and high gloss appearance plastic products. To produce the plastic product, the process parameters such as melt temperature, injection time, packing pressure, packing time, cooling temperature, and cooling time are conventionally adjusted through the trial-and-error method. Computer-aided engineering (CAE) is one of the alternatives in the PIM but the numerical simulation is computationally so expensive that the metamodel-based optimization is widely used to determine the optimal process parameters. First, typical metamodels including the sampling strategy are briefly reviewed. Then, the papers on the process parameters optimization for high product quality such as warpage, shrinkage, and weldline reduction are reviewed. Rapid heat cycle molding (RHCM) that actively controls the mold temperature is a novel PIM technology, but the process parameters optimization in RHCM is rarely discussed in the literature. Then, the RHCM is also reviewed in this paper. Not only the process parameters optimization but also the cooling channel plays an important role for high product quality and high productivity. Due to the recent advancement of metal 3D printer, it is possible to produce conformal cooling channel. It is possible to enhance the product quality and productivity by using the conformal cooling channel. Several papers on the process parameters using the conformal cooling channel are also reviewed.
