Quartz Glass Perforated Glass Plates – Quartz Glass (CTE 0.59 x 10^-6 /K, 260 nm – 2.5 um); Hole grids from 0.15 mm diameter, pitch from 0.5 mm. No minimum order; DFM review included with every RFQ.
We build quartz glass perforated glass plates to print – Hole grids from 0.15 mm diameter, pitch from 0.5 mm – primarily in Quartz Glass. Typical use: airflow sensors, filtration and vacuum chucks.

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 (hole 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.
Capabilities and limits
One material, many routes: on Quartz Glass we also quote double-side polishing, drilling, cnc machining, edge grinding, and multi-step drawings are the norm rather than the exception.
Production route: drilling, laser cutting, ultrasonic machining – selected per geometry and volume. Edge condition: optional chamfered hole entry.

Buyer questions, answered
Is there a minimum order for quartz glass perforated glass plates?
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.
