The mold must be baked in accordance with the regulations during the production process, and the material in the barrel must be correct. In order to prevent defective products or sundries from being injected into the mold, which may block the mold, the material pipe should be thoroughly cleaned. The tube temperature and mold temperature of the aluminum casting mold should be compatible with the processed raw materials. If you want to produce a more satisfactory aluminum casting mold product, you should adjust the pressure and injection volume. It should be noted that in the production process of aluminum casting molds, it is impossible to discharge burrs. Some cavity products are not completely solidified or even difficult to discharge burrs.

Small changes in the filling rate of the aluminum casting mold are likely to cause changes in the filling rate of the mold. Therefore, before adjusting various control conditions, it should be considered. In order to reduce the overall processing cycle time, reasonable adjustments should be made. In order not to reduce the product weight of the aluminum casting mold and damage the product performance, the screw advancement time cannot be shorter than the curing time of the gate glue. In order to make the product compact, it is necessary to extend the screw advance time when heating the mold.

During the production process of aluminum casting molds, do not rush to output, but wait patiently for the state of the machine and molds to stabilize. This is the main product part for measuring and recording continuous samples. When the sample is cooled to about room temperature, its important dimensions should be measured.

In order to check the stability of actual operation and obtain reasonable control tolerances, at least twelve complete mold samples should be produced continuously, with the date and number marked on the container, and placed separately according to the mold cavity.

This indicates that the processing conditions are still changing. The size of aluminum casting molds is indeed unstable, and some sizes have a tendency to increase or decrease. This is due to poor temperature control or oil pressure control; dimensional variations may not be within tolerances. If there is no change in the size of the aluminum casting mold and the processing conditions are normal, you can observe whether the quality of each cavity product is qualified and whether the size can be within the allowable tolerance range; measure and record the number of continuous aluminum casting molds that are greater than or less than the average The number of holes can be used to check the correctness of the mold size.
