Success Case Studies

Medical Surgical Instrument Parts
We manufactured precision micro-drilled stainless steel parts for a North American medical client. We achieved 0.15mm micro holes with 99.8% pass rate, provided full FDA compliant material certification, and delivered samples in 3 days.
Aerospace Sensor Components
For a European aerospace client, we produced sensor components with ±0.005mm position tolerance. The parts passed 1000-hour salt spray test, meeting the strict aerospace industry standards.
