Optimized for B2B efficiency, HONGMAO domes undergo rigorous testing: 500-hour salt spray resistance, 50gf cycle endurance, and 0.01mm tolerance precision. UL/CE-certified materials guarantee global compliance.
Industrial switches demand reliability. HONGMAO’s metal domes use 304 stainless steel with electropolished surfaces, ensuring smooth actuation and 10M+ cycles. Our domes maintain ±3% force consistency across -30°C to +85°C, outperforming competitors in automotive and IoT device testing.
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 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.
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.
