Exclusive Technical Expertise and Process Accumulation in the Aerospace Sector
With over 15 years of deep engagement in aerospace precision machining, we have served more than 50 global aerospace OEMs, research institutes, and Tier 1 suppliers. We have in-depth mastery of precision machining processes for aerospace-grade difficult-to-machine stainless steel, and possess core technologies including stress control, anti-deformation machining, and precision heat treatment of precipitation hardening stainless steel and high-temperature resistant stainless steel. We can perfectly solve the machining challenges of aerospace complex structural parts, ultra-thin wall parts, and high-precision mating parts, with rich full-cycle service experience in model matching, research trial production, and mass production.
Full-Chain 100% Traceability System Adapted to Aerospace Airworthiness Requirements
In response to the mandatory full lifecycle traceability requirements of the aerospace industry, we have built an exclusive digital traceability management system, achieving 100% full-process traceability from raw material incoming to finished product delivery. Each product is equipped with a unique traceability code, which can track full-dimensional data throughout the entire process, including the original mill heat number of raw materials, material certification, processing equipment parameters, operators, inspection records, heat treatment processes, and non-destructive testing reports. A complete traceability file can be delivered with the goods, fully adapting to the airworthiness management requirements of the world's major authorities including FAA, EASA, and CAAC.
Full-Closed Loop High-End Precision Manufacturing Capability with No Outsourcing Risks
We operate an independent Class 10000 clean machining workshop, 5-axis CNC machining centers, precision heat treatment workshop, non-destructive testing laboratory, and surface finishing production line, achieving full in-house control from raw material pre-treatment, rough machining, stress relief, finish machining, post-processing to inspection without any third-party outsourcing. This not only completely eliminates the risks of confidentiality breach, quality fluctuation, and schedule out of control caused by outsourcing, but also realizes unified control of the whole process technology and quality control, ensuring the confidentiality, consistency and reliability of aerospace products.
Exclusive Aerospace Compliance and Certification Capability
Our production system has passed the AS9100D Aerospace Quality Management System Certification (the core access certification for the global aerospace industry), NADCAP Special Process Certification (heat treatment, non-destructive testing), and has ITAR-compliant production capacity. We have in-depth familiarity with the world's major airworthiness specifications including FAA, EASA, and CAAC, and can provide a full set of process documents, First Article Inspection (FAI) reports, material traceability documents, and airworthiness supporting materials that meet the requirements of aerospace models, helping customers quickly complete model finalization and airworthiness certification.
Extreme Precision Control and Flexible Production Capability
We are equipped with imported 5-axis simultaneous CNC machining centers from DMG MORI (Germany) and Mazak (Japan), supported by high-end processing equipment such as precision grinding machines and jig boring machines. The maximum machining positioning accuracy can reach ±0.002mm, and the geometric tolerance is controlled within ±0.005mm, which can perfectly adapt to the micron-level accuracy requirements of aerospace products. At the same time, we seamlessly undertake orders of all volumes from single-piece research trial production, small-batch multi-variety model matching to 100,000-level mass production, perfectly adapting to the production characteristics of the aerospace industry of "multi-variety, small-batch, high requirements, and fast response".
Aerospace-Grade Full-Process Technical Empowerment
Our professional aerospace engineering R&D team, staffed with specialists in structural mechanics simulation, heat treatment process, non-destructive testing, and airworthiness management, provides customers with free DFM (Design for Manufacturability) and DFA (Design for Assembly) analysis. We intervene early in the product R&D stage to optimize product structure, material selection, processing technology and heat treatment solutions, and avoid risks such as stress concentration, machining deformation, and working condition failure in advance through finite element simulation. While ensuring product performance and reliability, we reduce processing costs, shorten model R&D cycles, and create core value for customers.
