Technical Capabilities: The Art of Precision
Our custom quartz fabrication process combines modern robotic precision with traditional craftsmanship. We offer a full suite of machining and assembly services to meet sub-micron tolerance requirements.
1. Multi-Axis CNC Machining
We utilize high-accuracy milling, slotting, and complex 3D contouring. Our 5-axis CNC centers allow us to machine intricate shapes from solid quartz blocks or large-diameter cylinders with tolerances maintained at +/- 0.01mm. This is essential for components like gas distribution showerheads and wafer pedestals.
2. Ultrasonic & Laser Micro-Drilling
For semiconductor and microfluidic applications, we provide clean, burr-free micro-hole drilling. Our ultrasonic technology allows for deep-hole drilling in quartz plates without compromising the structural integrity of the material, preventing micro-cracks that could lead to failure under thermal stress.
3. Expert Thermal Welding & Assembly
Our master glass blowers specialize in torch welding for flanges, gas inlets, and multi-chamber reactors. Every weld in our custom quartz fabrication workflow is followed by a rigorous controlled annealing cycle to ensure maximum stress relief, preventing spontaneous breakage during high-vacuum or high-temperature operation.
4. Advanced Surface Finishing
Depending on your application, we provide specialized surface treatments:
- Optical Grade Polishing: Achieving a transparent, scratch-free finish for viewport windows.
- Precision Grinding: For components requiring exact friction fits.
- Sand Blasting: For frosted effects or to increase surface area for specialized chemical coatings.

Specialized Custom Solutions for Industry
Our custom quartz fabrication team supports the world’s most demanding sectors with tailor-made components:
Semiconductor & Electronics
We manufacture critical process parts including quartz pedestals, gas distribution showerheads, heater shields, and wafer carriers. Our high-purity materials ensure that no metallic ions contaminate your cleanroom environment, maximizing wafer yield.
Laboratory & Chemical Research
From multi-neck flasks to specialized distillation columns and high-pressure reaction vessels, we transform standard Laboratory Quartz Glassware into complex, integrated systems.
Optical & Sensor Housing
We produce precision-ground quartz windows, sight glasses, and sensor protection sleeves. The broad spectral transmission of our quartz makes it ideal for optical housings used in UV sterilization and laser research.
Quality Commitment & Inspection
We understand that in high-precision environments, the reliability of a single quartz component can determine the success of an entire project. Our quality protocol includes:
Surface Purity Testing: Ensuring the component is free from ionic contamination and particulates.
Dimensional Verification: Using CMM (Coordinate Measuring Machines) to verify complex geometries.
Internal Stress Analysis: Every fabricated part is inspected under polarized light to ensure the success of the annealing process.
Maintenance & Handling of Custom Fabricated Parts
Due to the complex geometry and high precision of these components, special care is required:
- Strict Handling: Always handle custom parts with clean, powder-free gloves. Fingerprint oils can lead to permanent devitrification if the part is heated.
- Cleaning: We recommend a mild acid rinse (10% Nitric Acid) followed by high-purity water for decontaminating complex internal channels.
- Thermal Management: Avoid rapid local heating on complex welded joints. Even with professional annealing, uniform ramp rates (5°C to 10°C per minute) are recommended.
