Step Glass 2-15mm Round Step Tempered Glass Special-Shaped Optical Element

Step glass is a type of specialty glass with a stepped structure, processed through cutting, edging, tempering, and other techniques. It combines high light transmittance, thermal stability, and mechanical strength. Its core characteristics include:
Physical properties: Light transmittance ≥90%, temperature resistance range 180-1700°C, strong impact resistance, scratch-free and bubble-free surface, supports repeated cleaning without wear, deformation, or discoloration.
Processing flexibility: Customizable thickness (2-40mm), dimensions (5-400mm), and edge treatments (polished edges, rounded edges, etc.). The surface can undergo sandblasting, printing, acid etching, and other processes to meet various application needs.
Application fields and typical scenarios of step glass
Thanks to its optical and mechanical properties, step glass is widely used in lighting, electronic devices, and other fields:
Electrical equipment: Serves as display screens or protective components, such as the "Display Step Glass Protection Structure" developed by Truly Semiconductors, which enhances stability at the stepped areas through protective adhesive designs in the backlight frame, reducing the risk of breakage.
Customized scenarios: Supports color, pattern, and logo printing, suitable for special requirements like signage and decorative lighting.

The production of step glass involves multiple precision processes, with core techniques and equipment as follows:

1. Processing equipment: Glass cutting machines, edging machines, cleaning machines, tempering furnaces, screen printing machines, etc., ensuring dimensional accuracy and surface quality.
2. Tempering treatment: Enhances thermal stability and impact resistance through high-temperature heat treatment (referencing the 180-1700°C temperature resistance range). Thickness ≥3mm results in granular fragmentation (full tempering), while <3mm results in semi-tempering.
3. Customization process: Requires customers to provide CAD/PDF drawings specifying dimensions, materials, printing requirements, etc. Bulk production proceeds after sample confirmation.
