Precision Machining for Instrument & Laboratory Equipment
We manufacture high-precision components for precision instruments, laboratory equipment, and diagnostic systems — including functional components, connectors, fixtures, and precision housings. With ±0.01mm tolerances, diverse material capabilities, and full MES traceability, we support your instrument projects from prototype to production.
Precision Instrument Component Manufacturing Capabilities
We deliver high-quality custom-machined components for precision instruments, laboratory equipment, and diagnostic systems — functional components, connectors, fixtures, guides, and precision housings. Every project follows our full quality-control workflow, from raw material incoming inspection through final dimensional verification. We machine a wide range of materials including stainless steels, tool steels, copper alloys, and engineering plastics — detailed material capabilities are listed below. With 3 CNC machining centers, wire EDM, surface grinders, and precision inspection equipment including Nikon projectors and TESA height gauges, we ensure consistent quality across every batch. No minimum order quantity — we treat every part with the same rigorous quality standards.
