Precision Manufacturing at the Core – Building a Full-Process Technical Capability System

2026-6-30

Precision manufacturing capability is the core competitive advantage of automotive component enterprises. Zhejiang Zhongjia Lianhe Precision Engineering Co., Ltd. has consistently prioritized technological innovation, building a full product life-cycle technical capability system around core processes including precision machining, cold heading forming, and stamping and welding.

In terms of intellectual property portfolio, the company was granted an invention patent for “A Composite Multi-Station Ultra-Precision CNC Machine Tool” in 2022, marking a technological breakthrough in the field of precision machining equipment. Around its core products, the company has continuously secured multiple utility model patents, including “Cold Heading Forming Mold for Armrest Connecting Shafts,” “Fixtures for Gear Shaft Drilling,” “Assembly Fixtures for Combined Gears,” and “Shaping Molds for Special-Shaped Seat Shafts,” forming a relatively comprehensive intellectual property system.

Among these, the cold heading forming mold technology, through the integrated optimization of rod bundling, upsetting, and forming processes, can significantly improve material utilization rates and product mechanical properties, delivering higher cost-effectiveness to customers. The “Self-Centering Fixture for Transmission Parts” patent, through the precision coordination of elastic clamping structures and adjusting screws, achieves rapid positioning and adaptive clamping of transmission parts, effectively enhancing machining efficiency and assembly precision.

In 2025, the company’s R&D institution, the “Zhongjia Lianhe Precision Machinery Basic Components Municipal Enterprise R&D Center,” was officially accredited by the Zhoushan Municipal Bureau of Science and Technology, marking a new milestone in the construction of its technological innovation platform. In the same year, the company was recognized as a National High-Tech Enterprise, valid until December 2028, with its technical strength and innovation capability receiving authoritative recognition.

Relying on sustained technological accumulation, the company continuously optimizes its production processes, enhances product precision and consistency, ensuring that every product delivered to customers meets high-standard quality requirements.
