Inside our facility in Wilmington, our people work daily with fire, precision tools, and a genuine passion for glass. What began as manual craftsmanship has grown into one of the most automated quartz fabrication sites in our network — built for the rare combination of high-volume repeatability and one-of-a-kind custom work, side by side on the same shop floor.
Whether you're sourcing a single prototype for a new design or need thousands of identical parts delivered on schedule, our team moves between both worlds without switching facilities, partners, or quality standards. That flexibility is what customers across industries — from analytical instruments to industrial processing — rely on us for.
Why Wilmington
Most quartz fabricators are built for one thing: either highly customized, low-volume work, or standardized parts at scale. Wilmington was built for both. Our team designs and hand-finishes one-of-a-kind components the same week they run automated production lines for high-volume orders — using the same equipment, the same quality standards, and the same people. For customers, that means a single point of contact who can take a project from first prototype to full-scale production, without handing it off to a different facility along the way.
Expert Quartz Glass Fabrication
Combining skilled craftsmanship with advanced technology, we transform high-purity quartz into precision-engineered components for semiconductor, laboratory, industrial, and high-temperature applications.
Engineered for Extreme Environments
From complex quartz burners to custom assemblies, we transform high-purity quartz into precision-engineered solutions that perform in the world's most demanding thermal processes.
Precision Quartz Glass Ampoules
