Defect description: The casting base is destroyed or broken to form a filament-shaped gap, there are two kinds of penetration and non-penetration, there is a trend of development

cause:
1. The casting structure is unreasonable and the fillet is too small
2. Uneven stress on core pulling and ejection device
3. Mold temperature is too low
4. The mold opening and core pulling time are too late

Improve methods:
1. Check the casting structure, negotiate to improve the casting structure and increase the fillet
2. Modify the mold structure to ensure smooth demoulding
3. Increase the working temperature of the mold
4. Shorten mold opening and core pulling time


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.
