We manufacture N52 neodymium disc magnets according to customer drawings and application requirements. The product is mainly supplied for OEM components, sensors, compact motors, switches, positioning systems and other industrial magnetic assemblies.
Before production, we confirm the size, tolerance, magnetic grade, magnetization direction and working conditions. For new projects, sample testing is recommended before mass production so the final specification can be confirmed in the actual assembly.
High magnetic energy density for applications with limited installation space
Custom diameter and thickness according to drawings
Axial magnetization as standard, with other options available after technical review
Tolerance control based on assembly requirements and machining feasibility
Surface protection options selected according to working environment
Sample and trial production available before mass production
Stable repeat production for long-term OEM supply
Custom Manufacturing
Size & Tolerance
Diameter and thickness can be manufactured according to the drawing. Critical assembly dimensions can be controlled as key inspection items.
Magnetization
Axial magnetization is commonly used for disc magnets. Special pole direction or magnetization requirements should be confirmed before production.
Surface Protection
Surface treatment should be selected according to humidity, corrosion risk, adhesive bonding, press fitting or other assembly conditions.
Working Temperature
If the magnet is used near a motor, heat source or enclosed structure, please provide the actual working temperature during quotation.
