HONGMAO employs anti-microbial coatings and chemical-resistant substrates (e.g., PET films) to ensure patient safety. Our overlays feature laser-etched symbols for permanent legibility and ESD-safe materials to protect sensitive electronics. With ISO 13485 certification, we validate every batch for biocompatibility and sterilization resistance. Partner with HONGMAO for overlays that meet the exacting demands of diagnostic equipment, surgical tools, and wearable health tech.
Industrial machinery demands graphic overlays that endure extreme temperatures, oils, and mechanical stress. HONGMAO’s solutions use polycarbonate substrates with hard-coated surfaces to resist scratches and solvents. We incorporate IP67-rated seals to prevent moisture ingress and offer EMI shielding for noise-prone environments. Supported by CAD-driven prototyping and 24/7 engineering support, we help clients optimize overlay thickness, legend contrast, and bonding methods. Choose HONGMAO for overlays that reduce downtime and enhance operator safety in manufacturing, energy, and heavy equipment sectors.
Tactile feedback is essential for user-centric graphic overlays in machinery and IoT devices. HONGMAO integrates polyester domes or metal snap discs into overlays, providing crisp actuation and 1M+ cycle durability. Our designs accommodate backlighting (LED/EL) and transparent windows for LCD integration, while selective texturing improves grip in humid conditions. With ISO 9001-certified processes and a vertically integrated supply chain, HONGMAO delivers cost-effective solutions for high-volume orders. Trust our team to optimize your interface design for ergonomics, compliance, and long-term reliability.
