Custom Rectangular Glass Plates – Up to 600 x 400 mm, thickness 0.2 – 40 mm. No minimum order; DFM review included with every RFQ.
A drawing for custom rectangular glass plates is mostly a conversation about edges and datums. We produce them in fused silica, Borofloat 33, quartz and soda-lime at Up to 600 x 400 mm, thickness 0.2 – 40 mm, with length/width +/-0.05 mm as the controlling tolerance, and finish the perimeter per spec.
The numbers
| Geometry | Rectangular Glass Plates |
|---|---|
| Size envelope | Up to 600 x 400 mm, thickness 0.2 – 40 mm |
| Key tolerance | length/width +/-0.05 mm |
| RFQ inputs | PDF/DXF/STEP drawing, quantity brackets, surface and edge spec |
Specification advice
Three items decide most of the cost and lead time on this work:
- Hold the controlling dimension (length/width +/-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.
Process window
Production route: cnc machining, grinding, edge grinding – selected per geometry and volume. Edge condition: chamfered 0.1 – 0.5 mm as standard.
Who orders this
Orders for custom rectangular glass plates cluster in led packaging (groove covers, phosphor carriers, package windows); oled packaging (cover lids, frit-seal frames, fill-port plates); scientific instruments (reference flats, cells, prism mounts, stage inserts).
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 ITO coating process, custom FTO glass, fused silica wafers 2-12 inch.
Common questions
Do parts ship with inspection data?
Dimensional reports, surface certificates and material certs per melt are available; specify the level on the RFQ.
What sizes are available for rectangular glass plates?
Up to 600 x 400 mm, thickness 0.2 – 40 mm, held to length/width +/-0.05 mm.
Is there a minimum order for custom rectangular 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.
