1. Injection material. Materials with impurities or different suppliers, different batches of the same manufacturer, etc., different batches of materials processing technology are different.
2. Injection molding machine. Check whether the function of each part of the injection molding machine is normal, and consider the influence of temperature, pressure, time and other reasons, and control and adjust the injection molding machine.
3. Mold. The mold device should be appropriate, the temperature should be correct, and the injection parts should run smoothly in the mold.
4. Production process. To ensure that the pressure, temperature and time are consistent with the processing conditions provided by the material supplier, constantly check the accuracy of the injection speed and technology.
5. Injection time, temperature, pressure, back force can affect the quality of plastic barrel processing
