How automotive plastic parts suppliers improve the machining accuracy of injection molding

The machining accuracy of injection molding is achieved by the cooperation of injection mold, plastic raw material performance, injection molding machine performance and injection molding process. about. How do we provide machining accuracy during processing?

Methods to improve the precision of injection molding:

1. The design scheme of the mold structure should be good, and it should be able to achieve the best precision requirements.

2. The choice of mold material is more stable material with better toughness.

3. In the injection molding process, the injection pressure should be controlled accurately, so that the raw material melt can be evenly filled into the injection mold, and there should be no problems such as burrs due to excessive pressure.

4. Whether the injection speed is too fast or too slow, too fast will cause burrs and overflow. Too slow will result in insufficient precision and imperfect structure.

5. If the processing temperature is too low, the color of the raw material will be uneven, and if the temperature is too low, the fluidity will be poor, and the screw of the injection molding machine will be at risk of breakage.

6. Choose the right raw materials. Different raw materials have different shrinkage rates, which will also lead to changes in accuracy.

7. battery box manufacturers need to choose high-precision injection molding machines to achieve the accuracy.
