Explore our leading industrial-grade touch panels and customized ring touch button components.
Founded in 2010 and based in Guangzhou, China, we are an industry-leading manufacturer specializing in the research, development, production, and distribution of resistive touch panels, capacitive touch panels, custom cover glass, and full optical module bonding solutions. We supply highly tailored OEM and ODM services, catering to global markets with products verified by ISO 9001 and ISO 14001 certifications.
Our solutions are deeply integrated into sectors requiring extreme reliability, including high-precision medical equipment, heavy industrial automation, smart home interfaces, outdoor appliances, and biometric palm print payment systems.
The global demand for industrial user-interfaces is shifting rapidly toward robust, contactless, or highly integrated circular tactile components. As machines shrink and become more complex, the Ring Touch Button has emerged as a premium solution for medical consoles, rugged controls, and home automation systems.
Industrial environments mandate IP65 to IP69K ingress protection. Ring touch buttons are increasingly integrated with chemically strengthened cover glass (up to 7H hardness) to withstand chemical washdowns and high-pressure steam cleaning in clinical contexts.
Modern controls rely on custom capacitive algorithms that mitigate false triggers from water droplets, oil slick contamination, or thick heavy-duty work gloves, ensuring error-free operation in steel factories and commercial kitchens.
Integrating concentric LED indicators and localized capacitive resonance improves user response speed. This tactile and visual duality is standard for critical aerospace and premium smart home applications.
To produce HMI products that conform to global benchmarks, Guangzhou Xiangrui maintains highly specialized dust-free environments and state-of-the-art lamination machinery.
Our facility houses structured cleanroom workshops of Class 100, Class 1,000, and Class 10,000 standards. This prevents microparticle contamination during the optical bonding process, which is essential to ensure optical clarity, eliminate Newton's rings, and improve shock resistance for outdoor and military displays.
Through our dedicated R&D engineering team, we assist procurement managers in specifying optimal cover plate thickness (0.5mm to 10mm), surface treatments (Anti-Glare, Anti-Reflective, Anti-Fingerprint), and specialized controller board integrations (I2C, USB, RS232 interfaces).
We build mutual trust through strict adherence to international industrial frameworks, ensuring your supply chain remains seamless and compliant.
Every step, from raw material procurement (ITO films, sensor glasses, controller ICs) to finished product testing, follows highly standardized protocols to secure zero-defect performance.
Our engineering department continuously secures utility patents for capacitive touch noise suppression, ensuring compliance in high-EMI environments like welding facilities and engine rooms.
We maintain a reputation for prompt delivery and integrity, serving as an OEM/ODM partner for leading device manufacturers in Europe, North America, and Southeast Asia.
As we head toward smarter automation, our product development path prioritizes three main technological developments:
Developing touchless capacitive nodes that detect a user's finger up to 50mm away, creating highly hygienic controls for public terminals, elevator panels, and medical switches.
Integrating piezoelectric actuators to provide different vibrational patterns depending on the button's status, improving safety in critical situations where screens aren't visible.
Leveraging next-generation conductive polymers to create curved, non-planar touch surfaces that seamlessly blend into automotive dashboards and curved wearable devices.
Yes. By fine-tuning the sensitivity of our capacitive controllers (such as Cypress, EETI, or FocalTech) and optimizing the sensor structure, we ensure stable touch operations even when users wear thick industrial gloves.
Optical bonding fills the air gap between the sensor and cover glass with clear adhesive (LOCA/OCA). This eliminates internal reflections, improves light transmission by up to 90%, and prevents dust and moisture condensation.
We support fully customized cover glass solutions, including PMMA, chemically tempered glass, custom silk printing, irregular cutouts, and special anti-glare (AG) or anti-reflective (AR) surface treatments.
All touch panels undergo rigorous environmental testing (high temperature, high humidity, thermal shock) and functional inspections before packaging, backed by our ISO 9001 quality system.
