Frequently Asked Questions
Q
What materials are available for custom pins and shafts for circuit breakers?
We offer a wide range of materials including high-quality carbon steel, alloy steel, and stainless steel. Our engineering team will recommend the most suitable material based on your specific application requirements, operating environment, and performance expectations.
Q
What level of dimensional precision can you achieve in manufacturing?
Using high-precision CNC lathes, automatic lathes, and grinding machines, we can stably control tolerances of key dimensions — including diameter, roundness, and coaxiality — within ±0.01mm, meeting the stringent requirements of MCCB mechanical components.
Q
What surface treatment options are available for pins and shafts?
We provide multiple surface treatment options to suit different needs: Blackening/Blueing for aesthetic rust resistance, Zinc Plating/Nickel Plating for superior corrosion protection, and Polishing/Grinding to achieve mirror-level smoothness and reduced friction coefficients.
Q
Can you produce parts if I only have a sample or a concept, without full drawings?
Absolutely. Our experienced engineering team can work with complete drawings, physical samples, or even a basic concept. We will perform feasibility analysis, process design, and provide optimization suggestions to bring your requirements to life efficiently and accurately.
Q
How do you ensure the quality of every delivered component?
We implement full-process quality monitoring from raw material intake to final delivery. Our facility is equipped with optical projectors, hardness testers, and salt spray testers. We conduct 100% inspection or rigorous batch sampling to verify dimensions, hardness, and corrosion resistance, ensuring every part meets drawing specifications and industry standards.
Q
Can you handle both small prototype orders and large-volume production runs?
Yes. Our flexible production lines are designed to accommodate both rapid prototyping requests and large-scale volume orders. We prioritize quick response times and on-time delivery to help streamline your production cycle and reduce time-to-market.
