Soda-Lime Glass Special-Shaped Glass: Soda-Lime Glass (CTE 9.0 x 10^-6 /K, 360 nm – 2.0 um); Any DXF/STEP outline within 600 x 400 mm. Single-piece prototypes to production volumes, quoted from your drawing.
A drawing for soda-lime glass special-shaped glass is mostly a conversation about edges and datums. We produce them in Soda-Lime Glass at Any DXF/STEP outline within 600 x 400 mm, with contour +/-0.05 mm as the controlling tolerance, and finish the perimeter per spec.

Specification advice
Before sending the RFQ, check these against your drawing:
- Material note: higher CTE means edge chips propagate under thermal load, so edge finishing quality drives reliability.
- Hold the controlling dimension (contour +/-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.
For the complete framework, see the tolerance design guide and the holes and edges design guide.
Manufacturing capability
One material, many routes: on Soda-Lime Glass we also quote laser cutting, drilling, polishing, coring, and multi-step drawings are the norm rather than the exception.
Production route: cnc machining, laser cutting, edge grinding – selected per geometry and volume. Edge condition: chamfered 0.1 – 0.5 mm as standard.
Who orders this
The recurring buyers of soda-lime glass special-shaped glass: 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.
The fastest route to a quote is geometry: use the 3D builder below, draw a dimensioned 2D drawing from it, or open the site-wide custom glass machining 3D + 2D builder for fully custom parts.
Engineers scoping this work usually also review special-shaped glass plates, glass-bottom microplates, ultra-thin glass materials.
Common questions
Is there a minimum order for soda-lime glass special-shaped glass?
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.
