Each magnetizing coil and fixture is customized according to customer-supplied drawings and charging parameters. Our engineering team evaluates magnet dimensions, pole numbers, magnetic orientation, and required field intensity to create an optimized design.
Supports axial, radial (inner and outer), and irregular pole magnetization patterns for complex magnet structures — from two-pole to multi-pole configurations used in advanced motors and sensors.


The optimized coil geometry and low-loss material selection ensure fast magnetization cycles with minimum energy consumption and reduced heating effects.
Precision winding and simulation-verified design guarantee consistent field strength throughout the magnet surface, reducing leakage and improving magnetic performance consistency.
All fixtures and jigs are made from heat-resistant materials and are designed for long lifespan even under continuous industrial operation.
Compatible with Mag Spring® and third-party magnetizing machines. The fixture interfaces can be customized to match your existing charging equipment.
We offer simulation reports, magnetic field analysis, and recommendations on charging voltage, energy level, and machine setup to help you achieve optimal results.
