Post-processing Capabilities
- Anodizing (Aluminum Alloy): Hard anodization in natural color, black oxidation, improving corrosion resistance
- Nitriding (Stainless Steel, Alloy Steel): Surface hardening, enhancing wear resistance
- Sandblasting: Eliminate tool marks, achieve a uniform matte finish
- Electro-coating + Powder Coating: Uniform black coating, rust prevention
- Polishing: Reduce surface roughness, beneficial for subsequent painting or bonding
Typical Application Cases
1. Avionics Enclosure Prototype
A certain aviation electronics company needed to verify the assembly and heat dissipation performance of a new flight data recorder housing. It used PEI (Ultem) material processed by CNC machining, followed by sandblasting and silk-screening identification, delivering 5 units for environmental testing, successfully passing vibration and temperature cycle tests.
2. Lightweight Drone Bracket
A certain industrial drone manufacturer needed to produce a magnesium alloy motor bracket, requiring a 30% reduction in weight. Magnesium alloy five-axis CNC machining was used, with a precision of ±0.05mm, followed by micro-arc oxidation post-processing, achieving a 28% weight reduction compared to the original aluminum alloy solution, while meeting strength requirements.
3. Aircraft Interior Bracket Retrofit Part
A certain aircraft maintenance company needed to retrofit seat mounting brackets for a business jet, quantity 20 sets. Using 7075 aluminum alloy CNC machining, natural anodization, providing material certificates and dimensional reports, it passed the customer's acceptance smoothly.

Frequently Asked Questions
Q: What is the difference between aerospace prototypes and formal aerospace parts?
A: Prototypes are mainly used for design verification and assembly coordination, usually without airworthiness certification. However, the materials and dimensional accuracy match those of formal parts and can be used for functional testing.
Q: Can we provide material proof?
A: Yes. We can provide raw material guarantee certificates (traceable batch numbers), as well as final dimensional inspection reports.
Q: What is the maximum machining size?
A: 1200×800×500mm. Larger sizes can be processed in parts and then assembled.
