Rubber magnets are produced by mixing ferrite powder with rubber or PVC, calendaring or extruding into strips and sheets, then magnetizing with multi-pole magnetizing rolls.
Finished products may be printed, laminated, die-cut and packaged as fridge magnets or promotional items.

FAQ
Rubber Magnet Production Flow — FAQ
How is a rubber magnet magnetized in multiple poles?
Sheets and strips pass over a magnetizing roll with alternating pole patterns, imprinting a fine multi-pole magnetization across the width.
What quality checks apply to printed fridge magnets?
We inspect magnetic flux, dimensional accuracy, print colour and lamination adhesion before packaging.
Do you provide free samples for testing?
Yes, sample orders are welcome. Send your drawing or specification together with the intended application so our engineers can recommend the correct grade, magnetization direction and coating before we prepare samples.
Can the factory produce to my drawing with special tolerances?
Yes. We machine, grind and inspect to customer drawing tolerances. For sintered NdFeB the standard machining tolerance is ±0.05 mm and can be tightened to ±0.02 mm with diamond grinding where the geometry allows.
