Chemical Strengthening D263 Thin Glass: D263 Thin Glass (CTE 7.2 x 10^-6 /K, 350 nm – 2.0 um); CS > 600 MPa, DoL 8 – 40 um. Single-piece prototypes to production volumes, quoted from your drawing.

Specify chemical strengthening d263 thin glass when the bare substrate falls short: potassium ion exchange, processed by KNO3 salt bath, 380 – 450 C, brings D263 Thin Glass to CS > 600 MPa, DoL 8 – 40 um.

What the process holds

Beyond this page, D263 Thin Glass routinely runs through polishing, cnc machining, grinding, drilling in our shop – most real parts combine two or three of these steps.

Design guidance

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.
  • Sequence matters: all machining happens before chemical strengthening; post-coating rework is not economical.
  • 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.

Typical applications

Orders for chemical strengthening d263 thin glass cluster in medical diagnostics (flow cells, slides, microplate bottoms, cuvette windows); microfluidic devices (chips, manifolds, via plates, bonded stacks). Background reading on the underlying material science: SCHOTT D 263 thin glass.

Common questions

Is there a minimum order for chemical strengthening d263 thin 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.

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.

FREQUENTLY ASKED QUESTIONS
What machined features can be added to cover glass?

Edge grooves, a center cavity or an edge step for module packaging, each with adjustable width and depth. Functional coatings such as AR, anti-fingerprint, ITO or a black border print are also available.

Which edge finishes are supported?

As-cut, ground, polished or C-chamfer. The preview color-codes the edge and shows a double line for a C-chamfer.
