Defect description: After the liquid entering the cavity first forms an incomplete metal layer, the traces left behind by the later metal liquid make up, this defect has no development direction

cause:
1. The cross-sectional area of the inner runner is too small and improperly located
2. Low mold temperature
3. Filling speed is too high
4. Too much paint

Improve methods:
1. Adjust the cross-sectional area and position of the gate to achieve simultaneous filling
2. Measure the mold temperature and adjust the mold temperature to the process requirements
3. Adjust the filling speed to change the liquid state of the metal cavity
4. Adjust paint concentration and quantity

During the production of aluminum alloy die-casting parts, pay more attention to the changes in the details of the die-casting mold and die-casting machine, and take good methods as a habit, and the quality will be guaranteed.
