Sand Casting, Investment Casting and Die Casting in China

Quality Control

Based ISO9001 quality system, Casting Quality Industrial managed many processes to control the quality for metal castings.

From the raw material to final casting products, we monitor everything of sand casting and investment casting process.

How to control the quality? The necessary facilities will be widely used in every program:

Pump Penetrant Testing

Penetrant Testing for Pump Casing

1. Raw Material Quality Control: Generally, we should be check the chemistry property as new raw material coming. The raw material cover pig iron, strap steel, coal and sand

2. Production quality control: the Working Instruction will be confirmed before production. Then we will care every process based programs. Especially the first sample must be checked carefully.

3. We will check the chemistry again when the products are finished. We also check the mechanical property, such as tensile strength, yield strength, elongation and hardness.

4. To find the inner defect, we also use non-destructive method to check the products, such as ultrasonic testing, and radiography inspection. To find the surface crack, the magnetic particle testing and penetrating testing are also choices.

5. We will keep the records for about half years , then we will trace every batch.
