Engineered for harsh environments, HONGMAO’s metal domes feature 301/304 stainless steel with anti-corrosion coatings, operating in temperatures from -40°C to +120°C. Ideal for automotive, aerospace, and marine applications, our domes support IP67 sealing and EMI shielding integration.
Every HONGMAO dome undergoes:
Material inspection (SGS-certified steel)
Precision stamping (±0.02mm tolerance)
Surface treatment (anti-oxidation coating)
Force testing (digital force gauges)
Automated packaging (ESD-safe trays). ISO 14001 compliance guarantees traceability.
Tailor tactile response with HONGMAO’s domes:
Low-force (0.3N) for wearables
Medium (0.6N) for consumer electronics
High (1.5N) for industrial gloves. Our R&D team simulates 50+ actuation profiles for optimal UX.
HONGMAO’s saltwater-resistant domes feature 316L stainless steel and PTFE coatings, surviving 1,000-hour salt spray tests (ASTM B117). Ideal for naval equipment and offshore rig control panels.
HONGMAO’s automated stamping presses produce 2M+ domes monthly, reducing unit costs by 30% versus manual processes. Custom dome arrays (pre-assembled on PET carriers) streamline PCB integration for appliance and industrial panel OEMs.
