we manufacturing precision parts: cylindrical needle rollers; face driver pins, millimeterwave, submillimeter wave, microwave structure components. CNC custom precision machining ( intracavities, slot arraies, transitions, converters, switches, rotary joints, orthomode transducers OMT, feed horns, ulators, diplexers, isolators, multipliers, phase shifters, detectors, oscillators)

we located in Nanjing, a city that hosts multiple national‑level millimeter‑wave and sub‑millimeter‑wave research laboratories, we have built our reputation as a dedicated precision machining partner for the most demanding RF projects. for over 20 years,

we have supplied high‑performance waveguide structural parts and mechanical components to these leading institutions – including the state key laboratory of millimeter waves at university, defense research institutes, and other innovation centers across china.

our core strength lies in ultra‑high precision machining. Using advanced multi‑axis CNC machining centers, we produce complex waveguide bodies, UG‑387/U‑M flanges, cavities, and housings with tight tolerances (down to ±1 µm) and mirror‑like internal surfaces (Ra ≤ 0.1 µm). We work with a wide range of materials – oxygen‑free copper, brass, aluminum alloys, and Kovar – and offer in‑house gold plating to ensure low RF loss, excellent solderability, and long‑term reliability.

because we focus exclusively on the mechanical structure – not on active or passive electronics – we deliver parts that are ready for direct integration into your mm‑wave, sub‑mm‑wave, or terahertz systems. our experience covers the full WR series (WR‑3 to WR‑12), as well as custom‑designed components for antennas, filters, attenuators, splitters, and coaxial adapters.

we believe that high precision should not come with an unreasonable price tag. Simply send us your drawings , and we will provide you with the best product quality and the most competitive price in the market. Prototypes and small‑batch production are our specialty – no minimum order quantity required.
