How MGS Leads the Way in High-Purity
Fused Quartz Fabrication
Since 1989, Machined Glass Specialists (MGS) has been a pioneer in custom fused quartz, silica, and borosilicate fabrication. With the surge in demand for ultra-pure quartz components in semiconductors, photonics, solar, and optics, MGS blends decades of experience with cutting-edge fabrication for unmatched precision.
1. Why Fused Quartz Matters in High-Tech Industries
Fused quartz—or fused silica—is nearly pure silicon dioxide (SiO₂), prized for its extreme thermal stability, chemical resistance, and optical clarity across UV to IR ranges. It’s essential in semiconductor photolithography, UV optics, fiber optics, and solar applications due to its ultra-low thermal expansion and minimal impurities—qualities that MGS ensures in every part.
2. Advanced Fusion Techniques: Flame, Plasma & Electric Arc
MGS utilizes state-of-the-art fusion methods:
Flame fusion (Type II/III): Ideal for optical-grade quartz rods and tubes
Plasma fusion (Type IV): Produces ultra-high purity, low-OH glass suited for semiconductor optics
Electric arc fusion: Delivers bubble-rich glass for specialized industrial applications
These methods let MGS tailor quartz qualities like OH content, clarity, and thermal properties to your industry’s specific needs.
“I have worked with Dave for a number of years in the quartz industry. He has been the one to go to for all of my quartz machining work. The level of expertise and service is unmatched. Dave provides a level of attention to detail that is very hard to find. I highly recommend Dave and his company, MGS.”
3. Precision Machining: Drilling, Cutting, Polishing Excellence
MGS’s advanced fabrication includes:
Diamond wire-saw & laser cutting for smooth, stress-free cuts critical in UV-optic parts
Diamond drilling for clean micro-holes used in microfluidics and photonics
Grinding & chemical-mechanical polishing (CMP) yielding ultra-fine finishes for semiconductor wafer carriers and UV optics
4. Innovative Processes & Laser-Based Finishing
MGS stays ahead with innovation:
- Laser ablation + melt polishing removes subsurface damage economically, enhancing surface smoothness and laser damage thresholds
- Gelcasting and injection molding pave the way for complex-shaped silica ceramics, offering sustainable, low-waste alternatives
5. Market Trends: Growing Demand & MGS’s Strategic Role
Global fused quartz fabrication is accelerating with market growth expected between 4.5%–9.7% CAGR through 2030, driven by semiconductor, solar, and telecom industries. MGS is strategically positioned to serve this demand with its high-purity standards, precision machining, and fusion innovation. The U.S. market particularly emphasizes custom, responsive manufacturing solutions, a strength MGS offers since 1989.
