Adjustment method of stress mark of injection molding machine
2024-10-28
Choose the right injection pressure: injection molding machine injection pressure is too low or too high will lead to the generation of stress marks. The appropriate injection pressure should be selected to avoid excessive local pressure.
Reduce the holding pressure and time: too much holding pressure and too long time will increase the stress, and the holding pressure and holding time should be appropriately reduced.
Increase the mold temperature: If the mold temperature is too low, the stress cannot be released in time and remains. The mold temperature should be increased.
Specific operation steps
Adjust the injection pressure: According to the setting of the injection molding machine, gradually adjust the injection pressure until the appropriate pressure value is found.
Adjust the holding pressure and time: gradually reduce the holding pressure and holding time, and observe the change of stress marks.
Adjust the mold temperature: increase the mold temperature through the heating system to ensure that the mold temperature is within the appropriate range.
Through the above steps, the parameters of the injection molding machine can be effectively adjusted, the generation of stress marks can be reduced, and the product quality can be improved.
