Description
Felix Glass produces customized millimeter wave radar dustproof protective optical glass, also known as radar protective cover glass. As standardized core automotive safety parts for passenger fuel and new energy vehicles, our radar windows perfectly match front and rear 77GHz anti-collision millimeter wave radar modules. This ADAS radar dustproof window serves as collision avoidance radar cover for automotive active safety systems, with steady recurring bulk orders from global automotive Tier 1 suppliers and vehicle OEMs. Unqualified coating causes high electromagnetic attenuation and unstable radar signal output Coating peeling after temperature cycling, unable to meet long-term vehicle durability standards We adopt high-strength chemically strengthened aluminosilicate automotive radar tempered glass as substrate, reaching Mohs 7 hardness to achieve excellent scratch and impact resistance. It withstands gravel impact, sand abrasion, long-term UV radiation and rain corrosion during highway and off-road driving, avoiding permanent surface damage that weakens radar detection stability. Chemically strengthened aluminosilicate glass against stone impact and surface abrasion. Minimize millimeter-wave attenuation while repelling mud, snow, rain and road contaminants. Reliable optical performance from -40℃ to 85℃ with durable coating after thermal cycles. Our radar protective glass maintains stable optical and mechanical performance within full automotive temperature range. After thousands of hot-cold alternating thermal cycle reliability tests, the coating remains intact without peeling, cracking or transmittance decay. We support full customization: irregular CNC contour cutting, precise mounting holes, black light-shielding silk screen printing and edge chamfering, perfectly matching millimeter wave radar modules of mainstream vehicle brands. Irregular contour cutting according to customer engineering drawings. Surface polishing and edge chamfer treatment. Black light shielding printing for automotive radar assembly. Dual-function composite coating deposition inside cleanroom. CCD full-automatic optical inspection and dust-free packaging. ADAS millimeter wave radar module manufacturers for passenger vehicle active safety systems. Domestic and overseas EV & fuel car manufacturers for front/rear anti-collision radar assembly. Engineers requiring prototype sampling for new radar product verification projects. Specialized in automotive-grade precision optical glass custom manufacturing. All processes finished inside factory without outsourcing to control quality and lead time. Support rapid sample order for automotive project preliminary verification. CCD automatic inspection for flatness, transmittance, dimension and appearance. Mature bulk delivery experience serving global automotive industrial customers. Optimized for 77GHz automotive anti-collision millimeter wave radar, compatible with mainstream vehicle radar modules. Yes. We support CNC customized irregular shape, positioning holes and black shielding printing strictly per your engineering drawing. We support small-batch sampling for automotive R&D verification, then scalable mass OEM production after project confirmation. The AR+AF composite coating withstands thousands of -40℃~85℃ thermal cycle tests without peeling or failure. Share your DXF drawing, required thickness, coating requirement and order volume. Our automotive optical engineering team will provide customized solution and formal quotation for your ADAS millimeter wave radar assembly.
