Most of the electronic component injection molding using injection molding , these plastic parts due to the high precision of the design, the use of special engineering plastics processing , these parts can not use a conventional plastic injection molding process, using only precision injection molding process. In order to ensure the performance, quality, reliability and long-term stability of these precision plastic parts, plastic products produced by injection molding are of higher quality and meet product design requirements. They should be used in plastic materials, injection molding equipment, mold design, injection molding process and on-site Improve management and other aspects.

For precision injection products, molds are one of the keys to ensure the quality requirements of precision plastic products . Precision injection molds should meet the requirements of product size, accuracy and shape, and mold materials should be strictly selected. However, even if the accuracy and size of the mold are the same, the actual size of the molded plastic product will change due to the difference in shrinkage. Therefore, better shrinkage control of plastic products is an important link in the precision injection molding process.

Since the injection molding process transforms the plastic from solid (powder or granule) to liquid (melt) to solid (product), it has been widely used in precision injection molding. From pellets to melts, and then to melts, the temperature field, stress field, flow field and density field should be used in the middle. Under the combined action of these fields, different polymers (thermosetting or thermoplastic, crystalline Or non-crystalline, reinforced or non-reinforced) have different polymer structure morphology and rheological properties.
