1. The analysis of the product maintains a processing manufaturability, determine the mold pulling out smoke core way and ejector way, try to use a model more advanced mold cavity structure.
2. According to different material shrinkage of tool design, such as glass fiber reinforced polyamide 66 material produced keep frame, the ball pocket holes or hole is shrinkage rate take 1.2%, inner diameter and outer diameter size shrinkage rate, from 0.4% to 0.7%.
3. Try to the use of standardized, generalization and seriation design. Proper selection of the mould material, improve the mould manufacturing precision and reduce the surface roughness.
4. Strictly carry out the standard technology, abrasive must test first article inspection, qualified rear can be mass production to ensure the product intrinsic quality.
5. Strictly according to the injection molding process production procedures, such as to enhance polyamide 66 maintains a process requirements, abrasive must preheating, will obtain more satisfied radial tensile strength, will not appear brittle fracture.
