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."
We offer a variety of materials including high-quality carbon steel, alloy steel, and stainless steel, and will recommend materials based on your needs.
Performance EnhancementFor circuit breakers used in high-impact and high-wear applications, we professionally apply heat treatment, surface hardening, and other processes to significantly improve hardness and fatigue life.
High-precision CNC lathes and grinding machines ensure tolerances of key dimensions are stably controlled within ±0.01mm.
Superior Surface FinishStrict quality monitoring is implemented throughout the entire process, from raw material to finished delivery.
Advanced EquipmentEquipped with optical projectors, hardness testers, and salt spray testers to conduct 100% inspection or batch sampling.
Whether you provide drawings, samples, or just a concept, our team conducts feasibility analysis and process design.
Rapid ResponseFlexible production lines respond quickly to prototyping and large-volume orders, ensuring on-time delivery.
