Mingquan Industrial Jewels Co., Ltd.

Mingquan Industrial Jewels Co., Ltd. manufactures custom sapphire and ruby components for optical instruments, fluid control equipment, and precision measurement assemblies. Its work centers on single crystal aluminum oxide materials selected for Mohs 9 hardness, polishability, electrical insulation, and chemical stability. The portfolio spans sapphire windows, lenses, rods, and tubes; ruby orifice jewels, balls, and ball styli; ring and cup jewel bearings; check valve components; waterjet nozzle inserts; and geometry specific jewel parts. Components are made to customer drawings, samples, and mating part requirements, with material, geometry, tolerance, surface finish, and inspection criteria defined for the application.

Production combines machining, lapping, and polishing with in process and final inspection of critical dimensions, bore condition, surface finish, roundness, flatness, and assembly fit. The company aligns optical surfaces with requirements for wavelength, clear aperture, coating, crystal orientation, and flatness, while flow and contact parts are engineered around pressure, leakage, load, speed, lubrication, and mating materials. Its components serve semiconductor and process equipment, analyzers and metering pumps, CMM and machine tool probes, industrial sensors, waterjet systems, flow instruments, and precision mechanisms including meters, gauges, gyroscopes, and timing devices. Custom forms extend to prisms, hemispherical lenses, wire guides, stepped holes, and microfluidic control parts.
