Problems and solutions related to defective casting products (1)

In the die casting process, we should pay attention to the temperature of the molten metal and the mold, the pressure when the mold is filled, and the casting failure caused by the gas or air contained in the metal. Poor casting will reduce the strength, which is seriously related to the safety and quality of the product.

Usually, the common problems faced by die casting products are as follows:

1. Trachoma

2. Sag

3. Insufficient filling (not enough liquid metal flow)

4. Cold partition (cold pattern)

5. The product is broken and skewed

6. Break the chilled layer

7. Fusion lines

8. Die

9. Stick mold

10. Bubbles

11. Discoloration

12. Rough surface

13. Hardpoint

In addition to the above, there are various reasons for poor casting. For the quality assurance of die castings, quality inspection is essential. Micro voids, poor surface roughness, etc., are related to quality, so high-precision analysis, measurement, and evaluation are required. So we will carry out a strict quality test on each product.
