1. Adjust mold temperature
The deviation of molding machine temperature is usually caused by uneven mold temperature. Therefore, by adjusting the mold temperature, the stability of the molding process and product quality can be improved.
1. Check the mold heater to ensure that the heaters of each part can work properly. If there is a problem with the heater, it needs to be repaired or replaced to ensure uniform heating of the mold.
2. Adjust the mold temperature one by one according to the actual situation. It can be adjusted according to the changes in the product and the performance of the machine itself.
3. For special process requirements, segmented heating or temperature control strategies can be used to make the mold temperature more uniform.
2. Adjust the barrel temperature
Barrel temperature that is too high or too low will affect the molding quality, so it needs to be adjusted.
1. There are generally two ways to adjust the barrel temperature, one is to adjust the heater output power, and the other is to adjust the cooling water flow. It needs to be selected according to the actual situation of the machine.
2. For large molding machines, the barrel temperature is generally adjusted by regional division. It can be grouped and adjusted separately according to needs to ensure the uniformity of the barrel temperature.
3. Clean the heat exchange surface
The temperature deviation of the molding machine may also be caused by contamination or fouling on the heat exchange surface. Therefore, keeping the heat exchange surface clean and in good condition is also an important means to ensure the temperature stability of the molding machine.
1. Clean the heat exchange surface regularly to remove dirt and scale. You can use professional cleaning agents or steam for cleaning.
2. Check the temperature sensor on the heat exchange surface to ensure that the temperature can be accurately measured. If there is a problem, it needs to be replaced in time.
Through the adjustment of the above measures, the temperature deviation problem of the molding machine can be effectively solved, and the stability of the molding process and the product quality can be improved. At the same time, it is necessary to pay attention to the maintenance and maintenance of the machine to ensure that the machine can operate stably for a long time.
