MANUFACTURING SUPPORT
We coordinate materials, machining, finishing and inspection for component verification and ongoing procurement. Listed daily capacities: slicing 10 million pieces/day; grinding 10 million pieces/day; zinc plating 5 million pieces/day; nickel plating 2 million pieces/day.
Based on company materials from 2026. Process capacities cannot be added together. Available capacity and lead times depend on specifications, processes and scheduling.
Explore manufacturing & delivery →PROJECT SUPPORT
Provide drawings, specifications and quantities, then discuss the operating environment, magnetization direction and delivery milestones.
Evaluate machining with material grade, structural features, surface finishing and final coated dimensions considered together.
Discuss validation and acceptance criteria for sample dimensions, magnetic properties and assembly requirements.
Coordinate scheduling, inspection and delivery against approved technical requirements and procurement needs.
OUR CAPABILITIES
