Manufacturing Capabilities
Melting & Forming
High-purity fused silica melting and drawing of tubes, rods and basic shapes with controlled dimensions and purity levels suitable for semiconductor and optical use.
CNC Diamond Machining
Multi-axis precision machining for complex geometries, slots, holes and tight dimensional tolerances. Ideal for wafer boats, injectors and custom fixtures.
Oxy-Hydrogen Flame Forming
Skilled flame working for flanged tubes, multi-port assemblies, closed vessels and specialized shapes, followed by controlled annealing.
Polishing & Surface Treatment
Fire polishing and precision polishing to achieve low-particle surfaces for semiconductor use and optical-grade finishes for photonic applications.
Annealing & Stress Relief
Controlled thermal treatment to relieve residual stress and ensure long-term dimensional stability under high-temperature service conditions.
Inspection & Documentation
Dimensional verification, visual inspection, impurity analysis and full material certification support to meet customer quality and traceability requirements.
