The mold needs to be baked according to regulations during the production process, and the material in the barrel should 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 barrel temperature of the casting mold and the mold temperature should be compatible with the processed raw materials. If you want to produce a more satisfactory casting mold product, you should adjust the pressure and injection volume. It should be noted that it is impossible to remove burrs during the production process of the casting mold. Some cavity products are not completely solidified and even difficult to remove burrs.

A slight change in the filling rate of the casting mold is likely to cause a change in the filling rate of the casting 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 weight of the casting mold product and affect the product performance, the screw advancement time cannot be shorter than the gate glue curing time. In order to make the product compact, it is necessary to extend the screw advance time when heating the mold.

In the production process of 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 the casting mold 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 casting mold and the processing conditions are normal, observe whether the product quality of each cavity is qualified and whether the size can be within the allowable tolerance range; measure and record the number of continuous casting mold holes greater than or less than the average value to check the correctness of the mold size.
