Our display waterproof sealing rings are precision-molded from high-purity platinum-vulcanized silicone, engineered to provide reliable waterproof, dustproof, and anti-fog protection for various display devices. Designed for the unique structural characteristics of displays (LCD, OLED, LED, touch screens), the products integrate excellent sealing performance, weather resistance, and compatibility, meeting IP65-IP68 waterproof standards, RoHS, and REACH compliance requirements. They are widely used in outdoor displays, automotive displays, industrial control screens, medical monitors, and consumer electronic display devices worldwide.
Core Structure & Key Performance Advantages
Adopting one-piece molding technology, the sealing rings feature optimized cross-sectional designs (O-ring, U-shaped, rectangular, custom profiles) with precise dimensional control, ensuring tight fit with display casings, screens, and frames. This design achieves comprehensive performance superiority for display device sealing protection:
-
Superior waterproof & dustproof performance: Achieves IP65-IP68 waterproof grade, with water pressure resistance up to 10m (for IP68 grade) and effective dustproof (no dust penetration under harsh industrial dust environments). The integrated sealing structure eliminates leakage points, ensuring no water or dust enters the display interior even after long-term outdoor exposure or frequent cleaning.
-
Excellent temperature & weather adaptability: Continuous operating temperature range of -60℃ to 200℃, maintaining stable elasticity and sealing performance in extreme cold (outdoor low temperature) and high heat (automotive dashboard, outdoor direct sunlight). Resists UV radiation, ozone aging, and hydrolysis, with no hardening, cracking, or deformation after 5000h outdoor exposure, ensuring long-term sealing reliability.
-
Precise dimensional control & perfect fit: Inner diameter range of 10mm-500mm, cross-sectional size of 0.5mm-10mm, dimensional tolerance controlled within ±0.05mm. Supports custom cross-sectional profiles and sizes according to display device drawings, ensuring tight fit with display frames and casings, avoiding light leakage and screen edge warping.
-
Good compatibility & non-damaging properties: The silicone material has excellent compatibility with display screens (glass, OLED panels) and casings (plastic, metal), no adhesion or chemical reaction, and will not scratch the screen surface or corrode the casing. The soft texture effectively buffers the impact between the screen and the frame, reducing screen damage during transportation and installation.
-
Stable mechanical properties: Tensile strength ≥6MPa, elongation at break ≥300%, compression set ≤12% (72h at 150℃), ensuring stable sealing performance even after long-term compression. Resists vibration and impact, adapting to automotive, industrial, and outdoor display device working environments with frequent vibration.
Precision Manufacturing & Strict Quality Control
The production process strictly adheres to display sealing product standards, with full-process quality control to ensure product consistency and sealing reliability:
-
Raw material screening & preparation: Select high-purity medical/industrial-grade silicone raw materials with platinum vulcanizing agents, mixed uniformly via dual-screw mixing to ensure material stability. Raw materials undergo purity, thermal stability, and compatibility tests before use, ensuring no harmful substances and compliance with RoHS standards.
-
Precision molding & vulcanization: Adopt compression molding or injection molding technology, with mold temperature controlled at 170-190℃ and molding pressure at 2.0-3.5MPa. The one-piece molding process ensures structural integrity and uniform thickness, avoiding splicing seams and leakage risks. Post-vulcanization (200℃ for 10min) enhances mechanical properties and sealing performance.
-
Trimming & surface treatment: Automated trimming to remove burrs and excess materials, ensuring smooth surface and accurate dimensions. The surface is treated with anti-adhesion technology, avoiding sticking between sealing rings during storage and use.
-
Comprehensive testing: Each batch undergoes 14-item inspections, including waterproof pressure test, dustproof test, high-temperature aging test, compression set test, dimensional measurement, and compatibility test with display materials. The outgoing qualified rate reaches 99.8%.
Key Application Scenarios & Technical Verification
Our display waterproof sealing rings have been widely applied in 200+ display device manufacturers, solving core sealing protection pain points for various display products:
-
Outdoor Displays (LED/LCD Screens): Used for outdoor billboards, municipal information screens, and stadium displays. IP67 waterproof grade resists rain, snow, and dust, with UV resistance ensuring no aging or cracking after 2 years of outdoor use. A municipal engineering client reported zero display malfunctions caused by water/dust intrusion.
-
Automotive Displays: Applied for automotive dashboards, central control screens, and rear-seat entertainment displays. Resists high temperature (200℃ short-term) and automotive interior chemicals, with vibration absorption performance reducing screen jitter. Meets IATF16949 standards, helping an automotive brand pass vehicle waterproof tests smoothly.
-
Industrial Control Screens: Used for industrial control panels, machine tool displays, and workshop monitoring screens. IP65 waterproof grade resists industrial dust and coolant splashing, with corrosion resistance ensuring stable operation in harsh industrial environments. A machinery factory reduced display maintenance frequency by 80%.
-
Medical Monitors & Consumer Electronics: Applied for medical display monitors, smart watches, and tablet screens. Biocompatible silicone (meets USP Class VI for medical use) ensures safety for medical scenarios, with precise fit avoiding light leakage and improving display clarity. A medical device client passed GMP certification smoothly.
