In recent years, it has also introduced a fully automatic machining line for Japanese main bearing covers and a dedicated machining line for differential housings. The company has also developed four auxiliary production factories, forming a casting production flow operation that integrates melting, sand treatment, molding, and cleaning, as well as a series of complete product processing and quality control testing processes such as precision machining, non-destructive testing, and precision coordinate measurement. The company now has an annual production capacity of 70000 tons of ductile iron castings and a monthly precision machining capacity of 1.2 million pieces
