Discover our primary lineup of sub-micron precision components engineered for the most demanding electronic, semiconductor, and communication applications.
The industrial landscapes of optical networking, semiconductor fabrication, and aerospace telemetry demand unprecedented mechanical tolerances.
Machining regular steels is straightforward, but contemporary advanced tech demands controlled expansion alloys like Kovar (ASTM F15), Titanium alloys, Inconel, and oxygen-free copper. Supplying these demands specialized cutting-tool geometry, thermal management, and dynamic compensation technologies.
From deep-sea optical repeaters to orbital electronics, components must offer 100% barrier protection. Surface roughness (Ra values below 0.2 microns) and micron-level cylindricity are absolute parameters to allow flawless glass-to-metal and ceramic-to-metal seals.
Global OEMs require supply chains that are compliant with RoHS, REACH, and Conflict-Free mineral mandates. Sustainable engineering practices and material traceability are now structural requirements to participate in high-value tenders.

Analyzing the physics of controlled expansion and high-reliability operations in critical environments.
Kovar is notoriously difficult to turn and mill. It has a high tendency to work-harden rapidly, leading to fast tool wear, burr formation, and poor surface finishes if cut parameters are sub-optimal. At Xinyunyang, we employ rigid tooling, optimized cutter geometries, and tailored coolant strategies to achieve clean surface finishes. This is critical for glass-to-metal sealing (GTMS) integrity, where micro-grooves can lead to vacuum failures.
Our CNC turned parts are widely used in optoelectronic packages, laser diode modules, and microwave sub-systems. In these setups, our turned Kovar components serve as the base, connector pins, or perimeter frames. Our production process ensures that these parts are prepared to receive subsequent gold or nickel plating without pitting or peeling, complying with strict military and aerospace standards.
Optical Networking: Fiber-optic transceivers requiring precise coaxial turned connectors to prevent structural shift over temperature swings.
Semiconductor Tooling: High-vacuum chamber interior components machined to eliminate virtual leaks and outgassing issues.
Aerospace telemetry: Sensor housings that withstand rapid thermal transitions while maintaining hermetic isolation.
Technical questions, capability limits, and process specifics answered by our engineering department.
For high-volume production, we regularly achieve dimensional tolerances down to ±0.005 mm (5 microns). Under optimized configurations and utilizing Swiss-type high-precision turning centers, we can meet tight tolerances of ±0.002 mm, depending on material choice, component aspect ratio, and geometrical layout.
Kovar (ASTM F15) has a thermal expansion coefficient designed to match borosilicate glass and ceramic materials. This matching prevents stress cracks across operating ranges of -80°C to +450°C. We ensure quality by sourcing certified, conflict-free raw materials and utilizing sharp tooling inserts to prevent work-hardening and micro-tears on sealed surfaces.
We can consistently achieve surface roughness values down to Ra 0.4 µm directly off the lathe, and down to Ra 0.2 µm or better with post-machining processes like precision polishing or micro-honing. Surface finish control is key to optimizing RF signal transfer and maintaining plating integrity.
We utilize an ISO 9001 certified quality management framework integrated with our dynamic production scheduling system. This setup helps reduce lead times for standard orders by 15% to 20%. For critical prototyping runs, we offer flexible line configuration to fast-track setups without disrupting active wholesale production blocks.
