9D Explosion-proof Hydraulic Full Coverage Curved Glass Screen Protector





9D Explosion-proof Hydraulic Full Coverage Curved Glass Screen Protector for Honor Band 4 Smart Bracelet
Felix Glass supplies custom curved tempered glass screen protectors and touch cover panels for wearable smart bracelets, sports fitness trackers and portable wearable devices.
Full-wrap curved glass protection for wearable touch displays
We provide 6D and 9D full-wrap curved glass solutions with ultra-slim 0.2mm thickness, 9H surface hardness, anti-scratch, anti-impact and hydrophobic AF anti-fingerprint coating. All glass adopts 2.5D chamfer curved edge technology to eliminate sharp edges and help avoid chip breakage.
Supported processing includes precise CNC cutting matching bracelet screen outlines, full coverage arc forming, chemical tempering, oil-repellent coating and explosion-proof film lamination. The curved glass panels deliver clear light transmittance and long-lasting protection for wearable device touch displays.
All specifications shown are for reference. Final size, curvature and coating can be customized based on customers' wearable device drawings.
Core Curved Glass Material and Hardness Parameters
Typical values for custom 6D and 9D wearable curved glass projects. Final test standards depend on the drawing, curvature, adhesive structure and inspection plan.
Full coverage fitting for Honor Band 4
- Curve fitting design: Fits the curved edge of Honor Band 4 screen with no lifting and no white borders.
- Ultra-narrow invisible border: Does not block screen display or touch area.
- Soft hydraulic material: Supports automatic exhaust and bubble-free installation.
- No device interference: Avoids conflict with silicone strap buckle and bottom heart rate sensor.
- Color version compatibility: Matches black, navy blue and pink silicone strap versions.

Questions buyers often ask before sampling
Is this curved glass film only fit for Honor Band 4?
The shown version is matched to Honor Band 4. Other wearable models can be customized based on device drawings.
How are bubbles eliminated during installation?
The soft hydraulic layer supports automatic exhaust during lamination, helping achieve a bubble-free fit when the surface is clean.
Will 0.2mm glass affect heart rate sensor accuracy?
The protector is designed for the display area and avoids interference with the bottom heart rate sensor structure.
Can bulk OEM logo packaging be provided?
Yes. OEM logo, individual retail packaging and bulk packing can be discussed for screen protector orders.
What is the lead time for samples and mass production?
Lead time depends on drawing confirmation, tool preparation, curvature difficulty and order quantity.
