Testing

Zhuangzhi has established a mature quality control system that includes raw material testing, process control, and product quality testing to maximize the pass rate. Our factory is outfitted with various pieces of testing equipment to ensure every detail and completely fulfill your demands.

Spectra analyzer: detects the element composition before heat treating therefore, we can adjust the element concentration in real-time.

Metallography: magnifying the inner structure up to 100-500 times, the change after heat treating can be observed which helps evaluate the heating effect.

Sand detector: detecting the parameters of the sand mold like water content and hardness, strictly ensuring the details

Rockwell hardness tester: tests the HRC hardness parameters of the product.

Impact tester: testing the anti-impact and toughness properties.
