Capabilities and limits
One material, many routes: on D263 Thin Glass we also quote etching, double-side polishing, polishing, grinding, and multi-step drawings are the norm rather than the exception.
Production route: laser cutting, cnc machining, edge grinding – selected per geometry and volume. Edge condition: filamentation edge, optional post-polish.
DFM notes from the shop floor
The shop-floor rules that matter here:
- Material note: ultra-thin stock cannot take conventional clamping; parts are machined on wax or UV-tape carriers.
- Hold the controlling dimension (outline +/-0.05 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.
Application context
d263 thin glass glass covers shows up across led packaging (groove covers, phosphor carriers, package windows); microfluidic devices (chips, manifolds, via plates, bonded stacks); oled packaging (cover lids, frit-seal frames, fill-port plates).

Common questions
Is there a minimum order for d263 thin glass glass covers?
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.
What tolerances are achievable on D263 Thin Glass parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. Ultra-thin stock cannot take conventional clamping; parts are machined on wax or UV-tape carriers.
