What is the reason for the strain of injection products
Injection mold product strain is a common problem encountered by many injection mold factories. What is the reason? How can it be solved? Injection mold product strain is a problem encountered by many mold factories, the author summarizes the following reasons for injection mold factory strain
1. The inclination of the die is not enough, so the inclination must be increased
2. Core polishing, smooth polishing and good mould dragging
3. Is the injection pressure too high? High pressure will also lead to product strain, so it is necessary to adjust the parameters properly to reduce the pressure
4. The material of die cavity surface is better to reduce shrinkage. Plastic product strain depends on what material you produce, PP ABS, easy to solve. But PMMA has some difficulties. If the customer is not willing to change the transparency of PMMA and suffers from strain, it may be that the hardness of the core material is not enough, which leads to strain, so it is necessary to strengthen the hardness of the core. So the injection mold product molding attention to the above points, the product basically won’t strain
