With two decades of technical accumulation, Shanghai Jinxi Precision Machinery Co., Ltd. has built a complete service chain covering machining, surface treatment, precision inspection, assembly, and commissioning. Its ±3 µm machining accuracy reaches internationally advanced levels. In aerospace valve body production, the company achieves one-clamping completion of complex internal cavities, reducing traditional five-step processes to just two and raising product yield to 99.9%. After obtaining IATF 16949 certification, Jinxi Precision entered the supply chain of a major multinational automotive group, providing stable deliveries of ECU housings.
Multi-Axis Machining Breakthroughs
The company’s multi-axis technology opens new paths for complex structures. When manufacturing 5G base station waveguide ports, Jinxi Precision uses 5-axis machining centers with dynamic tool compensation to control dimensional variation within ±0.002 mm, ensuring high-frequency signal transmission loss below 0.2 dB/m. This capability has made the company a key supplier to telecom equipment leaders such as Huawei and ZTE, delivering over 500,000 precision waveguide components annually.
Global Standard Compatibility
The ability to work with multiple global standards is a major asset for international expansion. Jinxi Precision simultaneously masters Chinese GB, German DIN, Japanese JIS, and American ASTM standards. For aluminum alloy precision mounting brackets, the company adjusts heat treatment parameters to meet both the EU RoHS directive and North American UL certification requirements. This technical versatility has made exports account for 35% of total revenue, with products shipped to 12 countries and regions.
Material Adaptability
Significant progress has been made in understanding material behavior. To overcome stainless steel work-hardening challenges, Jinxi Precision developed proprietary tool coating technologies and variable-parameter cutting processes. In one medical device rotor housing project, surface roughness was improved from Ra 0.8 µm to Ra 0.4 µm, and coaxiality error was controlled within 0.005 mm. For lightweight aluminum needs, topological optimization and anodizing reduced the weight of an automation equipment mounting base by 30% while increasing rigidity by 15%.
Continuous Innovation
A dedicated innovation system ensures sustained competitiveness. A team of 30 R&D engineers works in a 6,000 m² smart production base, completing more than 20 process improvement projects every year. The company’s self-developed vision inspection system uses machine learning algorithms to detect defects at 0.001 mm resolution, tripling online quality inspection efficiency. In the field of non-standard automation equipment, Jinxi Precision has designed and built 12 custom production lines for the 3C electronics industry, serving global brands such as Apple and Samsung.
Responsive Service
A fast-response service mechanism creates a competitive moat. A 24/7 rapid-feedback team, supported by a digital management platform, provides end-to-end visibility from order reception and production scheduling to logistics. When a consumer electronics customer needed an urgent order, Jinxi Precision adjusted shifts and activated backup equipment to deliver 100,000 precision brackets in 72 hours — preventing potential production line losses of over RMB 10 million.
Broad Industry Coverage
Diverse industry applications prove the company’s technical versatility. From sealing parts for automotive electronics to implantable medical devices, from microwave components for telecom equipment to precision bushings for industrial robots, Jinxi Precision has developed more than 2,000 product solutions. In the Tesla Shanghai Gigafactory supply chain, the company’s battery management system connectors feature a special surface treatment that reduces contact resistance by 40%, noticeably improving battery pack energy efficiency.
Platform-Based Technology
Beyond CNC machining, Jinxi Precision integrates sheet metal fabrication, stamping, and injection molding to form a complete manufacturing platform — from prototyping to mass production. One drone company reduced new product development cycles from 6 months to 3 months and cut tooling costs by 55% by leveraging Jinxi’s multi-process platform. This comprehensive service capability has helped the company capture an 18% market share in the precision machining sector of the Yangtze River Delta region.
Smart Manufacturing Transformation
Adoption of smart manufacturing technologies has raised quality control to a new level. By deploying a Manufacturing Execution System (MES), Jinxi Precision achieves real-time equipment status monitoring, automatic adjustment of process parameters, and cloud-based quality data storage. In a typical aerospace component project, the system automatically detects tool wear trends and triggers replacement alerts, improving machining stability by 25% and reducing tooling costs by 18%. This digital management capability enabled the company to successfully pass NADCAP special process certification for Boeing.
