Custom Tempered Glass
Why Choose Thermally Tempered Glass for Cover Glass?
Safer Breakage Behavior
Fully tempered glass is designed to break into smaller, less-sharp fragments than ordinary annealed glass. This makes thermal tempering useful for cover glass, equipment windows and protective panels where safer breakage behavior is part of the finished-product requirement.
Higher Mechanical Strength
Thermal tempering creates surface compression that gives the finished glass higher mechanical strength than comparable annealed glass, subject to glass type, thickness, size and process conditions.
Compatible Surface Finishes
Tempered cover glass can be combined with compatible printing and surface treatments according to the glass material and process sequence, including project-specific AG, AR and AF options where technically suitable.
Better Thermal-Shock Resistance
Tempered glass handles temperature changes better than annealed glass, making it useful where the glass may experience repeated heating and cooling.
Made-to-Drawing Customization
Custom tempered glass can be produced to drawings with specified dimensions, shapes, holes, cutouts and edge profiles. Because fully tempered glass cannot be machined afterward, the complete geometry is defined before tempering.
Cover Glass & Display Integration
Clear tempered glass can be used as cover glass, display protection glass and equipment windows where transparency, mechanical strength and a clean finished appearance are required.
Project-Specific Impact Evaluation
For projects with defined impact requirements, glass material, thickness, dimensions, support condition and the specified test method should be reviewed against the customer requirement before production.

Manufacturing Guide
Thermal Tempering & Custom Fabrication Considerations
Custom tempered glass is defined by more than the tempering step itself. Material, thickness, finished dimensions, hole layout, edge quality, printing and surface requirements should be reviewed together because all structural machining must be completed before thermal tempering.
| Project Item | What to Confirm | Why It Matters |
|---|---|---|
| Glass Material | Clear, low-iron, tinted or other suitable thermally temperable glass | The material affects optical appearance, processing route and final tempering feasibility. |
| Finished Size & Shape | Overall dimensions, outline, corner geometry and dimensional requirements | The complete finished geometry must be established before tempering. |
| Holes & Cutouts | Hole diameter, position, spacing, slots, notches and internal cutouts | All drilling and structural machining are completed before thermal tempering. |
| Edge Finish | Polished, satin, seamed, beveled or other project-specific edge requirements | Edge quality affects handling, appearance and the reliability of the finished glass part. |
| Printing | Borders, logos, icons, masking areas and functional graphics | The printing method and ink system must be coordinated with the tempering sequence. |
| Surface Treatment | AG, AR, AF or other compatible surface requirements | Surface treatments should be selected according to optical targets and process compatibility. |
| Impact / Test Requirement | Customer test method, impact target or referenced standard where applicable | Evaluation should be based on the actual finished-part dimensions and project requirement. |
| Production Stage | Prototype, small-batch validation or repeat production | Sampling allows geometry, appearance and process sequence to be confirmed before batch production. |
Process Sequence Is Critical
Cutting, holes, slots, cutouts, machining and edge finishing are completed before thermal tempering. Printing and compatible surface treatments are scheduled according to the selected material and finished-part specification.

Technical FAQ
Custom Tempered Glass FAQ
What is tempered glass and how is it made?
Tempered glass is heat-treated glass. During the glass tempering process, the glass is heated close to its softening range and then rapidly cooled with air. This creates surface compression and internal tension, increasing mechanical strength and giving fully tempered glass its characteristic safer fragmentation pattern.
What is the difference between thermal tempering and chemical strengthening?
Thermal tempering strengthens glass by heating and rapid cooling, while chemical strengthening uses ion exchange to create compressive stress near the glass surface. Thermally tempered glass is known for its small-fragment breakage pattern; chemically strengthened glass can retain sharper fragments when broken. The suitable process depends on glass thickness, material and product requirements.
Can you make custom cut tempered glass?
Yes, but the glass is cut to the required size and geometry before thermal tempering. Fully tempered glass should not be cut afterward because machining releases the internal stress and normally causes the entire piece to break.
Can custom tempered glass include drilled holes, slots and cutouts?
Yes. Custom tempered glass can include drilled holes, slots and cutouts, but these structural features must be completed before thermal tempering. Drilling or machining fully tempered glass can cause immediate breakage.
What processing should be completed before glass tempering?
The final outline, holes, cutouts, CNC machining and edge finishing should normally be completed before the glass tempering process. Printing is scheduled according to the ink system: ceramic ink is typically applied before thermal tempering, while suitable low-temperature inks may be printed afterward.
Does glass thickness affect ball-drop impact performance?
Yes. Ball-drop performance is affected by glass thickness, glass size, material and strengthening condition. Impact requirements should therefore be evaluated using the actual finished-part dimensions and the test method specified for the project.
How is the strength of tempered glass tested?
Depending on the project, tempered glass can be evaluated with impact or ball-drop testing and, where applicable, a fragmentation test after breakage. The required test method, impact energy and acceptance criteria should be confirmed against the customer specification or referenced standard.
How can I tell whether glass has been strengthened?
Visual inspection alone is not a reliable way to confirm strengthening. Chemical strengthening can be checked with stress-measurement equipment, while thermal tempering is normally verified through the production record and the appropriate strength or fragmentation test.
Can tempered glass be printed or coated?
Yes. Tempered glass can include silk-screen printing and selected surface finishes. The process order matters: ceramic printing is generally done before thermal tempering, while some low-temperature printing and coating processes can be applied after tempering. The sequence should be confirmed for the specific material and finish.
Can GelivableGlass manufacture tempered cover glass to customer drawings?
Yes. GelivableGlass manufactures custom tempered cover glass and precision glass panels to customer drawings. Dimensions, shapes, holes, slots, cutouts and edge profiles are completed before thermal tempering, while compatible printing, AG/AR/AF treatments and bonding requirements are planned around the finished specification.
What is the difference between tempered cover glass and ordinary tempered glass panels?
Tempered cover glass is usually a finished precision component made to the geometry and visual requirements of a display, touch interface or equipment front panel. In addition to thermal tempering, it may require precise holes, cutouts, edge profiles, printed borders, functional surface treatments and bonding features.
What information is needed for a custom tempered glass quote?
Please provide the drawing, glass size, thickness, material, quantity, hole and cutout details, edge requirements, printing artwork, surface finish and any impact or test requirements. This allows us to review the tempered glass fabrication sequence and sample-production options.
