Is Your Current Medical Touch Cover Supplier Causing These Problems?
| Pain Points With Other Suppliers |
Felix Glass Solution |
| Ordinary glass scratches easily from frequent cleaning and touch operation, reducing display readability over time |
Single-crystal sapphire delivers Mohs 9 surface hardness — second only to diamond among optical materials — providing inherent scratch resistance from routine handling and repeated cleaning, supporting a stable viewing surface over extended equipment service life. |
| Chemical disinfectants corrode ordinary glass and coatings, causing coating peeling and haze after long-term use |
Sapphire is chemically inert and nonporous, resisting attack from alcohol, medical disinfectants and cleaning agents. We review substrate, ink, adhesive and coating as one stack against your specific disinfectant protocol, concentration, dwell time and wipe cycles. |
| Suppliers do not understand medical device cleaning protocols or biocompatibility requirements, cannot provide documentation support |
Dongguan Felix Glass Co., Ltd. aligns incoming material records and inspection outputs with your OEM qualification plan. We provide material records, dimensional/cosmetic/optical/coating inspection records, and change control inputs to support your medical device material qualification process. |
| AF coating cannot withstand repeated wiping, contact angle drops after a few hundred cycles, fingerprints become difficult to clean |
Our AF and AR+AF coatings are engineered for medical cleaning durability. Up to 5,000 alcohol wipes can be established as a project acceptance target, with test liquid, wipe material, load, speed and pass/fail criteria agreed before validation. |
| Poor tolerance control on custom sizes, cutouts and printing causes assembly fit problems |
We perform precision CNC machining, optical polishing and edge finishing with strict dimensional verification. Drawing-based geometry including rectangular/contoured outlines, radiused corners, slots, holes, notches, camera windows and sensor apertures is manufactured to your approved tolerances. |
| Supplier requires high MOQ, blocking medical device early-stage prototype validation |
We support 1-piece prototype testing for medical sapphire touch covers, allowing you to verify optical performance, coating durability, touch response and assembly fit before committing to production volumes. |
| Difficult to find one supplier for sapphire precision machining + medical-grade coating + clean packaging + documentation support |
We provide integrated control across sapphire blank preparation, CNC machining, optical polishing, AF/AR+AF coating, cleanroom packaging and full inspection documentation — one supplier from prototype to mass production for your medical touch cover project. |

Frequently Asked Questions Before Ordering
Q: Is sapphire automatically biocompatible for every medical device?
A: No. Material properties can support a biological safety assessment, but suitability depends on the finished device, contact type (patient, operator, indirect, no-contact), duration, processing residues, coatings, adhesives and applicable evaluation plan. The medical device manufacturer remains responsible for device classification, design controls and biological evaluation.
Q: Can the sapphire touch cover survive 5,000 alcohol wipes?
A: That can be established as a project acceptance target. The result must be tied to a defined alcohol concentration, wipe media, applied load, stroke length, speed, dwell time and coating acceptance criteria. Test liquid, wipe material and pass/fail criteria must be agreed before validation.
Q: Will sapphire work with a capacitive touch sensor?
A: Often yes, but the complete stack must be validated. Thickness, dielectric behavior, adhesive, sensor pattern, controller tuning, glove mode and display geometry can affect touch performance. We recommend production-intent sample evaluation in your finished assembly with your sensor, adhesive, display and firmware stack.
Q: Should we select AF or AR+AF coating?
A: AF prioritizes easier cleaning and reduced fingerprint visibility. AR+AF also addresses reflection and glare, but needs spectral range, reflectance target, color neutrality, durability and process evaluation against the actual display assembly. Our engineers can recommend the suitable coating based on your operating environment and display specifications.
Q: What should a quotation drawing include?
A: Provide dimensions, tolerances, datum scheme, edge profile, openings, printing, clear aperture, coating zones, cosmetic criteria, inspection standard, thickness requirement, annual demand and required sample quantity. Incomplete specifications are acceptable for preliminary engineering evaluation.
Q: What standard thickness options are available?
A: Standard thickness references are 0.5mm, 0.8mm and 1.2mm. Custom thickness is available upon request. Thickness selection should consider touch sensor performance, mechanical strength requirements, weight constraints and your device housing design.
Q: Can you provide medical device material certification documentation?
A: We can organize a project documentation package around the approved drawing and purchase specification, including material identification and supplier documentation, dimensional/cosmetic/optical/coating inspection records aligned with your control plan, and change control inputs (drawing revision, approved sample, critical-to-quality features, packaging definition, lot traceability). Available records depend on material source, coating design, test scope and order requirements.
Q: Is sapphire an FDA-approved material?
A: Sapphire material is not "FDA approved" by itself. The US medical-device manufacturer remains responsible for device classification, design controls, biological evaluation (ISO 10993 as applicable), verification, validation and regulatory submission. We provide material records and inspection data to support your qualification process.
Q: How long does a custom medical sapphire touch cover prototype take?
A: Typical prototype lead time is 2–3 weeks after specifications are confirmed. Actual timing depends on geometry complexity, coating type, printing requirements, inspection scope and current production schedule. Production-intent samples are built to the approved revision for assembly, optical, touch, cleaning and reliability evaluation.
Q: Can you manufacture custom cutouts, printing and masked coating zones?
A: Yes. We support drawing-based custom geometry including rectangular or contoured outlines, radiused corners, slots, holes, notches, camera windows and sensor apertures. Decorative printing, masked coating zones and optical bonding compatibility review are available. All custom features are confirmed during engineering drawing review before production.
