In today’s challenging global supply chain environment, B2B buyers increasingly value a physical factory’s actual delivery capabilities and supply chain control. Since our establishment in 1990 , CNCJPARTS has consistently invested heavily in building a complete in-house production line—from product design and mold development to final assembly.

Our hardcore manufacturing strength isn’t just on paper; it is practically implemented across our four core production workshops:

• Stamping & Mold Workshop: Equipped with 16 heavy stamping machines and 120 molds , we independently handle mold development, component stamping, and product forming.
• Heat Treatment Workshop: Featuring 5 specialized machines , we are experts in critical processes including carbonitriding, quenching, tempering, and phosphating.
• Laser Welding & Assembly: We strictly control product consistency through high-precision laser welding, and independently complete clutch assembly and finished product testing in our assembly workshop.

Having formed this closed-loop industry chain , we efficiently manufacture a wide range of clutch covers with specifications ranging from 350mm to 430mm. Currently, our steady annual production capacity reaches 800,000 clutch discs and 800,000 clutch covers.
