the processing factors of injection molding
- Apr 17, 2018 -
In the production of diamond plastic wires, it is necessary to carry out injection processing, so now we introduce the impact factors in the injection molding process.
Injection molding - affecting factors Plastic injection molding process due to the existence of the formation of the volume change, injection molding processing pressure is high, the melt viscosity difference is small, the shear stress between layers is small, after the release elastic bounce, so Shrinkage injection molding process can also reduce the amount of injection molding temperature, high shrinkage, but the direction of small.
When the pressure is increased during injection molding, the molten material is subject to shearing action and fluidity. In particular, PE and POM are more sensitive. Therefore, the molding pressure should be adjusted to control the fluidity during injection molding. Molding can also control the material temperature, mold temperature and injection molding processing pressure, injection speed and other factors to properly adjust the filling to meet the molding needs.
