Influencing Factors in Plastic Injection Process

Plastic pallets are a widely used logistics container, and their production process is also affected by some factors. In the plastic injection process, due to the change in volume caused by crystallization, the pressure during processing is high, the viscosity difference of the molten material is small, the interlayer shear stress is small, the elastic rebound after demolding is large, and the shrinkage can be reduced appropriately. The material temperature is high, the shrinkage is large, but the directionality is small.

In the plastic injection process, as the pressure increases, the molten material will have a large shear effect, and its fluidity will also increase, especially PE and POM are different, so during molding, it is necessary to adjust the pressure during processing to control the fluidity. During molding, it is also necessary to control the material temperature, mold temperature, and the pressure and injection speed during injection molding to properly adjust the filling situation to meet the molding needs.

Qingdao Xueyu Molding Products Co., Ltd. is mainly engaged in the design and manufacturing of injection molds, injection molding and secondary processing (spraying, pad printing, ultrasonic welding, stamping), etc. For more information about plastic injection process, please contact us.
