Success Case Study
Aerospace Aluminum Bracket Manufacturing
Challenge
The client needed a high-precision aluminum bracket for aircraft actuator, with strict tolerance requirement of ±0.005mm, and the thin-wall structure was easy to deform during machining.
Solution
Our engineering team optimized the fixture design to reduce deformation, and adjusted the cutting parameters through our 20-year aluminum processing experience. We also used in-process measurement to compensate for deformation.
Result
We achieved 98.7% yield rate in mass production of 50,000 pcs, all parts passed the client’s incoming inspection, and the delivery was 15 days ahead of the client’s schedule.
