The company has established a complete quality management system and has obtained the IATF16949 quality management system certification. It standardizes the quality management at the production site, implements process inspections, and ensures that the production site is in a quality-controlled state. Quality control management activities are carried out for each process, and quality responsibility system assessment is implemented. 

The company conducts strict inspections from the time raw materials are brought into the factory and throughout each production process. It is equipped with a complete set of testing instruments for various performance indicators such as molds and core sands. In terms of controlling the cast iron material, it is equipped with a furnace front thermal analyzer and a German Spiegal direct reading spectrometer to quickly analyze the chemical composition of the iron water before and after processing, ensuring the quality of the castings. For each batch, mechanical performance tests, metallographic tests, and product size tests are conducted for each type of cast iron, and ultrasonic flaw detection tests can also be carried out according to customer requirements. At the same time, product archives and transfer cards are established for traceability management of the products, preventing defective castings from flowing into the next process.
