Soda-Lime Glass Glass Covers: Soda-Lime Glass (CTE 9.0 x 10^-6 /K, 360 nm – 2.0 um); 0.1 – 3 mm thick, contours to drawing. Single-piece prototypes to production volumes, quoted from your drawing.
soda-lime glass glass covers are ordered for display, sensor and LED package covers. The geometry envelope is 0.1 – 3 mm thick, contours to drawing, held to outline +/-0.05 mm, in Soda-Lime Glass.

Design guidance
Three items decide most of the cost and lead time on this work:
- Material note: higher CTE means edge chips propagate under thermal load, so edge finishing quality drives reliability.
- 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.
Manufacturing capability
One material, many routes: on Soda-Lime Glass we also quote polishing, etching, coring, ultrasonic machining, 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.
Application context
soda-lime glass glass covers shows up across led packaging (groove covers, phosphor carriers, package windows); industrial displays (touch covers, gauge windows, printed bezels). Background reading on the underlying material science: ASTM C1036 flat glass standard.

Frequently asked questions
Is there a minimum order for soda-lime 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 Soda-Lime Glass parts?
Ground features hold +/-0.01 mm and lapped thickness reaches +/-0.003 mm. Higher CTE means edge chips propagate under thermal load, so edge finishing quality drives reliability.
