Adjust the temperature
- Adjust the barrel temperature
Adjust the melt temperature to the appropriate range. Be careful not to adjust it too high or too low, which will lead to a decrease in melt quality or even material rejection.
- Adjust the refrigerator mold temperature
Adjust the appropriate refrigerator mold temperature according to the requirements of the injection molded product and the structural characteristics of the refrigerator mold. Generally, adjust the upper mold temperature first, then adjust the lower mold temperature, and finally keep it warm. It should be noted that each time the temperature is adjusted, the operating status of the injection molding machine should be monitored to ensure that the temperature rises or falls gradually, and there should be no rapid fluctuations or drastic changes.
Adjust the pressure
- Adjust the injection pressure
According to the product requirements and the characteristics of the mold structure, adjust the appropriate injection pressure. It is recommended to start debugging at low pressure and low speed, and gradually increase the injection pressure and injection speed to achieve a stable production state.
- Adjust the holding time
The holding time is one of the important factors affecting product quality. According to the product requirements, perform appropriate holding time debugging to ensure that the product density, size, surface finish and other indicators meet the requirements.
Adjust the speed
- Adjust the injection speed
Adjust the appropriate injection speed while ensuring the injection pressure. Generally, adjust the speed to a low level first, and then adjust it gradually to ensure the smooth molding of the product.
- Adjust the mold closing speed
Adjusting the mold closing speed is the key link to ensure product molding. Generally, adjust the mold closing slowly first, then accelerate after the mold contacts, and finally maintain a stable speed to ensure product quality.
Precautions
- Before adjusting the machine, make sure the mold surface is clean and apply mold release agent.
- injection molding machine and make adjustments in time. If any abnormal situation occurs, the machine should be stopped in time to troubleshoot the
- During the adjustment process, the equipment operating procedures should be strictly followed, and it is forbidden to adjust the equipment parameters without authorization.
- After the adjustment is completed, the equipment parameters should be recorded clearly and standardized for next use. At the same time, the injection molding machine should be maintained and maintained as necessary.
In short, the adjustment of the injection molding machine after the mold is installed is the key link to ensure product production. It is necessary to strictly follow the adjustment steps to ensure product quality.
