Precision injection molding and ordinary injection molding

by:NJPE     2020-01-25
Today, NJPE precision mold manufacturers will take you to know about precision injection molds and ordinary injection molds. What is the connection between the two and what standards and requirements do they have respectively, today NJPE is announced for everyone. The characteristics of precision injection molding are: the size of injection molded parts requires high precision and small tolerance. The conditions that must be met to meet the requirements of precision injection molding are: 1. The material of the mold is good, the rigid foot, the dimensional accuracy of the cavity, the smoothness and the positioning accuracy between the templates are high. 2. Precision injection molding machines should be adopted. 3, to use precision injection molding process. 4. Materials suitable for precision injection molding process shall be selected. Most of the commonly used precision injection molding materials are as follows: POM, pom cf (Carbon fiber), pom gf (Glass fiber dimension), PA, FRPA66 (Enhanced PA), PC, etc. The important method to ensure the dimensional accuracy of injection molded parts in the precision injection molding process is to control the shrinkage of injection molded parts, including: thermal shrinkage, disguised shrinkage, orientation shrinkage, compression shrinkage and elastic recovery of injection molded parts. The characteristics of ordinary injection molding are: the dimensional accuracy requirements for injection molded parts are not high, generally can be assembled as the standard, the appearance requirements for injection molded parts are relatively high, and secondary processing may be used if necessary (Such as oil injection)To improve appearance defects. Ordinary injection molding does not require a particularly precise injection molding machine, nor does it require specially specified materials, and commonly used thermoplastics can be used for production. Therefore, ordinary injection molding technology is also widely used in modern plastic industry.
