Screw positioning parts

The main features of precision injection molding are as follows:

1. Product dimensional accuracy is high, and the tolerance range is small, that is, the dimensional deviation of precision plastic products is within 0.03mm, and even micron-level inspection tools rely on projectors.

2. The product has high repeat accuracy. The main manifestation is that the part weight deviation is small and the weight deviation is usually below 0.7%.

3. The mold material is good, the rigidity is sufficient, the cavity size accuracy, cleanliness, and the positioning accuracy between the templates are high.

4. Using precision injection molding machine equipment.

5. Using precision injection molding technology to accurately control mold temperature, molding cycle, part weight, and molding production process.

6. Choose materials suitable for precision injection molding, such as PPS, PPA, LCP, PC, PMMA, PA, POM, PBT, glass fiber or carbon fiber engineering materials, etc.

The main factor of precision injection molding.

To inject precision plastic products, the five elements of material selection, mold design and processing, injection molding technology, molding personnel's technical level, and precision injection molding machine are indispensable. The accuracy of precision plastic products includes dimensional accuracy, shape accuracy, and surface accuracy corresponding to dimensional tolerances, shape tolerances and surface roughness. Dimensional accuracy is an important manufacturing and use quality index for plastic products.
