Quartz Glass Glass Plates With Holes: Quartz Glass (CTE 0.59 x 10^-6 /K, 260 nm – 2.5 um); Holes 0.15 – 100 mm in plates to 40 mm thick. Single-piece prototypes to production volumes, quoted from your drawing.
A drawing for quartz glass glass plates with holes is mostly a conversation about edges and datums. We produce them in Quartz Glass at Holes 0.15 – 100 mm in plates to 40 mm thick, with position +/-0.02 mm as the controlling tolerance, and finish the perimeter per spec.

Capabilities and limits
One material, many routes: on Quartz Glass we also quote coring, sandblasting, grinding, polishing, and multi-step drawings are the norm rather than the exception.
Production route: drilling, coring, laser cutting – selected per geometry and volume. Edge condition: optional chamfered hole entry.
DFM notes from the shop floor
The shop-floor rules that matter here:
- Material note: natural-quartz batches vary in metallic ppm, so semiconductor lots need certs per melt.
- Hold the controlling dimension (position +/-0.02 mm) and let secondary dimensions carry standard tolerance – it is the single biggest cost lever.
- Over-specification is the quiet budget killer: a 20/10 scratch-dig face costs roughly three times an 80/50 face, so grade each surface individually.
The full rules live in our tolerance design guide and holes and edges design guide.

Buyer questions, answered
Is there a minimum order for quartz glass glass plates with holes?
No. Single prototypes are accepted, and pricing steps down at 10, 100 and 1,000 pieces.
How fast can prototypes ship?
Machined prototypes ship in 5 – 10 working days. Coated or bonded parts add 1 – 2 weeks depending on queue slots.
What files do you need for a quote?
A dimensioned PDF plus DXF or STEP geometry. If only a sketch exists, our drawing review service formalizes it before quoting.
Do parts ship with inspection data?
Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.
