Knowledge about the Inspection of Al Die Casting Before Use

The Al die casting is a very advantageous product, and it is very necessary for reasonable use. The Al die casting is adopted in many places in life, and the value of the product itself will be very high.

1. What are the main inspections of Al die casting before use?

The Al die casting is developing rapidly in the current machinery industry, and its application is becoming more and more extensive, and its technology is also getting better and better. The Al die casting mainly uses its own gravity to cast objects. This casting method is entirely based on physical principles. Compared with other casting methods, it protects the environment better. Therefore, we must pay great attention to each aspect of inspection before production.

2. Inspection method of the Al die casting

The inspection of Al die casting often uses penetrating coloring detection, which wets or sprays the colored liquid with high penetrating ability on the surface of the casting. The penetrant penetrates into the opening defect, quickly wipes off the surface penetrating liquid layer, and then the display agent which is easy to dry (also called developer) is sprayed on the surface of the casting. After the penetrant remaining in the opening defect is sucked out, the display agent is dyed, which can reflect the shape, size and distribution of the defect.
