In the automotive parts industry, quality management directly impacts supply chain security and overall vehicle quality. Zhejiang Zhongjia Lianhe Precision Engineering Co., Ltd. has always regarded quality as the lifeline of its corporate development, establishing a quality management system that covers the entire product life cycle.

In 2025, the company passed the automotive industry quality management system certification, marking that its quality management level has reached international standards for the automotive industry. Building on this foundation, the company obtained environmental management system certification in 2024 (Certificate No. MSC24E10002R0S, valid until January 2, 2027), achieving dual-system standardization in both quality and environmental management.

At the process level, the company’s self-developed “Self-Centering Fixture for Transmission Parts” patented technology, through the precision coordination of elastic clamping structures and adjusting screws, achieves rapid positioning and adaptive clamping of transmission parts, effectively ensuring machining accuracy and product consistency from the clamping stage. Additionally, the multiple tooling patents arranged around core products provide hardware support for process quality stability.

On the customer side, relying on its stable and reliable product quality and delivery performance, the company has successively won multiple honors including “Outstanding Supplier” from Zhejiang Geely Transmission, “Outstanding Supplier” from MWES (China), and the “Outstanding Contribution Award” from Zhoushan 7412 Factory.
