Custom 1.1mm Tinted Grey Tempered Cover Glass Sheets
(Precision CNC 2.5D Edge Grinding | Ion-Exchange Chemical Strengthening | Custom Optical Silk Screen)
【OEM/ODM Manufacturing Capabilities】
As a specialized optical cover glass manufacturer, we deliver turnkey custom fabrication for 1.1mm Tinted Grey Display Cover Glass Panels tailored to Tier-1 electronics brands, smart switch manufacturers, and HMI display integrators worldwide.
Our state-of-the-art facility features high-precision CNC machining centers, automated high-temperature chemical strengthening baths, precision cleanroom silk screen lines, and optical spectrophotometer testing equipment.
【Manufacturing & Engineering Strengths】
High-Purity Tinted Substrate: Sourced from optical-grade grey float glass with consistent color density, free from bubbles, inclusions, or surface scratches.
Custom Tunable Transmittance: Silk screen ink formulas and screen mesh densities can be fine-tuned to achieve target visible light transmittance (15% to 50%) and near-infrared (850nm / 940nm) pass rates for sensors.
Tight CNC Tolerances: Dimension and cutout tolerances controlled within +/- 0.05 mm, with smooth 2.5D round-edge polishing to prevent stress concentration.
Deep Chemical Strengthening Layer: Depth of layer (DOL >= 8–12 um) and surface compressive stress (CS >= 450–650 MPa) ensuring superior flexural strength and IK code compliance.

【Frequently Asked Questions (FAQ)】
Q1: Can the visible light transmittance of the semi-transparent ink be adjusted to our specific LED brightness?
A: Yes. By adjusting the pigment formulation, dilution ratio, and screen mesh count, we can precisely tune the optical transmittance (e.g., 20%, 30%, 40%) to match your display brightness and ambient light requirements.
Q2: What files and specifications are required to receive a formal quotation and sample?
A: Please provide your 2D engineering drawings (PDF / DWG / DXF) detailing dimensions, tolerances, and edge chamfers, along with silk-screen artwork (AI / CorelDraw / PDF) indicating translucent zones and Pantone/RAL color codes.
Q3: How are the glass panels protected and packaged for international export?
A: Each glass panel is laminated with dual-sided anti-static, residue-free PE protective film. Panels are packed in dust-free slotted cassettes or separated by high-grade interleaving foam, vacuum-sealed inside moisture-proof bags, and crated in shockproof export cartons and wooden boxes.
Q4: What is your standard production lead time?
A: Standard sample fabrication takes 7 to 10 working days. Mass production typically takes 12 to 16 working days depending on order quantity and processing complexity.
