General plastic injection parts molds have two indicators, which are equipment accuracy and Optical Cable Connector Box mold error. The former is not easy to compare due to differences in size and product thickness, which represents the comprehensive level of injection molding machines. The weight repeat error of ordinary injection molding machines in general At about 1%, better machines can reach 0.8%, less than 0.5% are precision machines, and less than 0.3% are ultra-precision machines. So what are the main factors affecting Plastic Injection Parts mold products?
 
         1. Consider the shrinkage of plastic.
 
         2. Product shape and size The shape and size of plastic parts.
 
         3, the accuracy of mold plastic parts, its mold processing accuracy.
 
         4. The injection molding machine has higher precision requirements for products.
