Why Customers Choose Us & Technical Problems We Solve

Strict coaxiality control. RF parts require high concentricity between inner and outer conductors. We stabilize geometric tolerances to prevent poor VSWR and excessive high-frequency loss, solving unstable signal issues during high-frequency testing.

High plating yield control. Plating directly affects conductivity and corrosion resistance. Our pre-treatment process avoids blistering, pinholes and uneven plating, maintaining stable electrical performance under high & low temperature environments.

Machining for complex threads & special profiles. We process various standard RF threads, flanges and adapters in one-stop CNC turning, reducing cumulative errors from repeated clamping. Support flexible production for small & mass orders.

Excellent part consistency. Low dimensional variation in mass production, good interchangeability. No secondary matching required for customer assembly, lowering assembly defect rate.

Compliance & on-time delivery. RoHS compliant. Material and plating test reports available. Fast prototyping and stable mass production to support customer new product development.
