Custom 1.1mm & 2.0mm Ultra-Clear Tempered Glass Panel
1. Product Overview & Key Engineering Highlights
Chenshi Tech is an established manufacturer specializing in custom ultra-clear glass panel manufacturing and precision cover glass fabrication. Built using high-purity low-iron float glass substrates, each glass panel delivers an exceptional visible light transmittance exceeding 91.5% with virtually zero iron-oxide greenish edge tint.
Complementing our specialized chemically strengthened etched AG glass panels and smoked grey display cover glass, our standard ultra-clear glass panel provides optimal structural rigidity, optical transparency, and surface flatness for electronic touch screens, industrial instrument viewports, and lighting fixtures.

3. Engineering Advantages of Low-Iron Ultra-Clear Glass
-
Uncompromised Optical Clarity: Standard float glass contains ferric impurities that cast a distinct green shade across the face and along the edges. Our low-iron glass panel maintains total color neutrality and vivid chromatic reproduction, making it essential for true-color graphic displays and medical diagnostic screens.
-
High Mechanical Strength via Tempering: Through precision chemical ion-exchange or physical thermal tempering, each finished glass panel withstands surface compressive stresses up to 650 MPa and meets IK07/IK08 drop ball standards without structural warpage.
-
Seamless Module Integration: Equipped with CNC-chamfered perimeter edges and tight thickness tolerances (± 0.05 mm), every glass panel mounts cleanly into metal bezels or plastic frames using precision die-cut 3M adhesives or direct optical bonding (OCA).
4. Custom CNC Machining & Secondary Fabrication
Chenshi Tech provides end-to-end custom secondary operations to supply ready-to-assemble front panel components:
-
Precision CNC Profiling: Custom rectangular outlines, circular viewing ports, contoured CAD geometries, 2.5D pencil rounded borders, and safe polished arrises.
-
Ultrasonic Drilling & Sensor Cutouts: High-accuracy camera pinholes, speaker slits, microphone apertures, and capacitive tactile button notches.
-
Ceramic Frit Printing: High-opacity black border framing, multi-color corporate branding logos, semi-transparent indicator windows, and scratch-resistant ceramic inks fused into the glass.
-
Thin-Film Optical Coatings:
-
Anti-Reflective (AR) Coating: Magnetron vacuum sputtering boosting overall light transmission to over 96% and minimizing glare.
-
Anti-Fingerprint (AF) Layer: Hydrophobic oleophobic coating providing a water droplet contact angle over 115 degrees, repelling smudges, finger grease, and water spots.
-
5. Target Application Sectors
-
Electronic Touch Monitors & Kiosks: Capacitive touchscreens, ATM screens, point-of-sale (POS) terminals, and interactive wayfinding displays.
-
Medical Diagnostic Equipment: Blood analysis displays, patient monitoring touchscreens, and surgical console protective windows.
-
Smart Home & Industrial HMI: Thermostat control screens, smart home touch panels, CNC machine operator interfaces, and security access keypads.
-
Precision Optical Sight Glasses: Pressure chamber inspection windows, flowmeter viewports, and luminaire protective faceplates.
6. Frequently Asked Questions (FAQ)
Q: What is the main difference between standard float glass and an ultra-clear low-iron glass panel?
A: Standard clear float glass features an inherent greenish tint caused by higher iron oxide content. An ultra-clear low-iron glass panel uses refined raw materials to lower iron content below 0.015%, delivering a crystal-clear edge, higher total luminous transmission (>91.5%), and zero color distortion.
Q: Should a 1.1mm or 2.0mm glass panel be chemically strengthened or thermally tempered?
A: Glass sheets with thicknesses under 2.5mm (such as 1.1mm or 2.0mm) are strengthened using chemical ion-exchange molten salt baths (KNO3). Chemical tempering prevents the roller-wave distortions and visual birefringence typical of physical thermal tempering, ensuring high surface flatness for touch sensor bonding.
Q: Can you deliver custom shapes with pre-applied adhesive gaskets?
A: Yes. We offer precision die-cut adhesive backing using genuine 3M materials (such as 3M 467MP, 3M 300LSE, or custom waterproof foam gaskets) positioned accurately along the printed borders for immediate assembly.
Q: Can this glass panel combine multiple optical coatings like AR and AF?
A: Yes. We frequently manufacture multi-functional panels combining vacuum-sputtered anti-reflective (AR) coating with an easy-to-clean anti-fingerprint (AF) oleophobic top layer.
