Learn how to enhance your production line with cutting-edge technology for superior result.

In order to reduce internal stress and surface quality defects, attention should be paid to the following issues in the injection molding process:

Special screws and injection molding machines with separate temperature controlled nozzles should be selected;

Under the premise that the plastic resin does not decompose, it is advisable to use a higher injection humidity for the injection temperature;

Injection pressure: generally high to overcome the defect of high viscosity of the melt, but too high pressure can generate internal stress, causing difficulty in demolding and deformation;

Injection speed: Under the condition of filling the mold, it is generally advisable to have a low injection speed, and it is best to use a slow fast slow multi-stage injection;

Pressure holding time and molding cycle: under the condition of meeting the product filling requirements without producing dents or bubbles; It is advisable to keep it as short as possible to minimize the residence time of the molten material in the barrel;

Screw speed and back pressure: On the premise of meeting the plasticizing quality, they should be as low as possible to prevent the possibility of degradation;

Mold temperature: The cooling quality of the product has a great impact on its quality, so the mold temperature must be accurately controlled during the process. If possible, the mold temperature should be higher.
