Process: Acid-etch, sandblast, CNC-cut for cut frosted glass projects. Available Thickness: 5mm frosted glass is most popular for balancing privacy and light; available up to 19mm on request. 3. Manufacturing Flow of Frosted Glass (Process Diagram & Highlights) Process Steps: 1. Float Glass Preparation ( Key: EN 572 compliance ) → 2. Cutting (CNC/Waterjet for cut frosted glass ) → 3. Surface Treatment (acid etch or sandblast; particle size & acid concentration monitored per ASTM E2167 ) → 4. Washing & Curing → 5. Edge Finishing (polish/grind per requirement) → 6. Final Inspection ( ISO 9001/ANSI Z97.1 standard tests for haze, transmission, surface flaw, impacts) Material: Float glass, optical clarity with iron content <50 ppm for premium grade. Manufacturing Process: Acid Etching: HF acid reaction forms a silica-haze surface for privacy and diffusion. Sandblasting: Abrasive blasting ensures uniform diffusion, widely chosen for patterns or cut frosted glass decorative use. CNC Cutting: Ensures cut frosted glass achieves custom shapes, holes, and slots to ±0.5mm tolerance. Quality Control: Online haze meters, visual flaw inspection, and mechanical stress tests per ISO 12543 . [See Frosted Glass Manufacturing Video] 4.
