What are the main factors affecting precision injection molding products?

General precision injection molds have two indicators, namely equipment accuracy and mold error. The former is difficult to compare due to the difference in size and product thickness, and represents the comprehensive level of injection molding machines. Generally, the weight repetition error of ordinary injection molding machines is 1%. A good machine can reach 0.8%, less than 0.5% is a precision machine, and less than 0.3% is an ultra-precision machine. So what are the main factors affecting precision injection mold products?
1. Consider the shrinkage rate of plastic.
2. Product shape and size Shape and size of plastic parts.
3. The precision of mold plastic parts and its mold processing accuracy.
4. The injection molding machine has high precision requirements for the products.
