These assemblies allow for drop-in replacement and modular equipment construction.
Quartz Tank Fabrication Capabilities
FGQuartz provides complete quartz tank fabrication capabilities for both standard and highly customized requirements. As a professional quartz tanks manufacturer, we support full custom quartz tank fabrication based on customer drawings, from simple modifications to complex multi-chamber process baths.
Our quartz tank fabrication services cover a wide range of precision operations, allowing us to deliver finished components that are ready for direct use in semiconductor wet benches, solar wafer cleaning lines, chemical laboratory systems and high-purity wet processing equipment.
Core Fabrication Capabilities:
• Cutting — Precision cutting of quartz plates and tubes to exact dimensions with clean, square edges. Suitable for custom tank walls, bottoms, and internal baffles.
• Drilling — Accurate drilling of holes in various diameters and positions. Used for side ports, drain holes, liquid level sensor openings, and multi-connection designs on custom quartz tanks.
• Grooving & Slotting — Precision grooving and slotting for locating features, internal wafer guides, cassette support structures, and specialized fluid dynamic requirements.
• Thread Machining — Internal and external thread machining. We produce custom threaded ports and fittings for mechanical connection, chemical circulation lines, and drain valves.
• Grinding & Polishing — Dimensional grinding and surface polishing to achieve tight tolerances on tank flatness, parallelism, and surface finish. We can provide optical-grade polishing for sensor windows and transducer mounting surfaces.
• Plate Bending / Thermal Forming — Controlled thermal slumping and bending of quartz plates for curved tank bottoms or seamless rounded corners, reducing stress points in the tank geometry.
• Quartz Welding — High-purity seam welding for quartz plates to create robust, leak-free tank joints. Maintains material integrity and outstanding chemical resistance.
• Flange Welding — Integration of top lips and heavy-duty flanges onto quartz tanks for reliable equipment mounting and overflow structural support in wet benches.
• Port & Pipe Welding — Welding of side fill ports, drain tubes, and circulation manifolds to create custom fluid handling tank assemblies.
• Custom Assembly — Complete fabrication of multi-part quartz tank systems that combine plate cutting, slotting, precision grinding, and seam welding into a single finished component.
