In modern electrical systems, molded case circuit breakers (MCCBs) are critical circuit protection devices, and their reliability, accuracy, and service life are paramount. Among these components, seemingly small pins and shafts are actually the core "joints" ensuring their mechanical transmission performance. We specialize in providing high-performance, high-precision pin and shaft hardware component customization services to major circuit breaker manufacturers. With superior materials, exquisite craftsmanship, and rigorous quality control, we infuse your circuit breaker products with a stable and reliable "soul."
A variety of materials including high-quality carbon steel, alloy steel, and stainless steel, recommended based on specific functional needs.
Performance EnhancementApplication of heat treatment and surface hardening to significantly improve hardness, strength, and fatigue life for high-impact uses.
High-precision CNC lathes ensure tolerances of key dimensions — diameter, roundness, and coaxiality — are stably controlled within ±0.01mm.
Superior Surface FinishStrict quality monitoring throughout the entire production cycle, from raw material warehousing to delivery.
Advanced Testing EquipmentOptical projectors, hardness testers, and salt spray testers ensure 100% inspection or batch sampling to meet standard requirements.
Support for complete drawings, physical samples, or concepts with professional feasibility analysis and process optimization.
Rapid Response & DeliveryFlexible production lines to handle prototyping and large-volume orders with on-time delivery guarantees.
