Tempered Glass Hole and Cutout Rules
Engineering-focused guidance for material selection, processing route, drawing review and custom glass quotation.
Comparison Table
| Option | Use When | Review Point |
|---|---|---|
| Borosilicate Glass | Stable industrial or laboratory parts | Thermal shock and edge finish |
| Quartz / Fused Silica | High temperature or optical use | Purity, polish and machining cost |
| Optical Glass | Sensor or vision assemblies | Surface quality and coating |
When to Choose Each Option
Choose based on temperature, transmission, chemical contact, thickness, available tolerances and budget.
Common Mistakes
- Missing edge finish or hole tolerance notes.
- Sharp internal corners on fragile glass cutouts.
- Choosing a material without reviewing operating temperature.
Drawing Checklist
Include material, dimensions, quantity, edge finish, surface requirement, coating, application and destination country.
