Facility Areas
Six Production Zones
Raw Material Warehouse
Climate-controlled storage for quartz billets, sapphire boules, and ceramic blanks, with incoming QC quarantine zone.
CNC Machining Center
Five 5-axis CNC grinding and milling machines for precision cylindrical, flat, and profile grinding. Coolant systems help prevent thermal deformation.
Diamond Wire Saw Area
Precision slicing for quartz and sapphire wafers with controlled cutting conditions to minimize surface damage.
Polishing & Lapping Room
Multi-stage lapping and polishing lines for optical and industrial-grade surface finishing, with Ra down to <0.05 μm.
Thermal Processing Zone
Hydrogen-oxygen flame working station for tube bending, welding, flaring, and annealing in a controlled environment.
Cleanroom & Packaging
ISO Class 7 cleanroom for final cleaning, inspection, and vacuum packaging.

Material loading and cutting
Quartz and ceramic blanks are cut before grinding, machining, and polishing.
Laser cutting setup
Laser processing supports precise outlines and selected small-feature cutting tasks.
Double-side grinding and polishing
Dedicated finishing equipment controls flatness, parallelism, and surface quality.
Quartz flame working
Hydrogen-oxygen flame working is used for forming and welding quartz assemblies.
Flame working workshop
Operator-controlled stations support custom quartz tube forming and welding.
Quartz annealing furnace
Annealing relieves thermal stress after flame working and high-temperature processing.
CMM dimensional inspection
Coordinate measurement verifies critical dimensions against customer drawings.
Inspection station
Optical and measuring instruments support routine in-process verification.
Visual inspection
Operators check appearance, handling marks, and release condition before shipment.
Ultrasonic cleaning tank
Quartz components are cleaned in ultrasonic baths before final inspection and packing.
Automatic ultrasonic cleaning
Racked parts move through automated cleaning steps for consistent cleanliness.
Production equipment
Process equipment supports controlled heating and component handling steps.
