FAQ

Magnetic Assemblies — Frequently Asked Questions

What is a magnetic assembly?
A magnetic assembly is a permanent magnet combined with structural parts such as steel housings, screws and brackets. The steel concentrates and directs the magnetic field, multiplying holding or lifting force.
Can assemblies be made per customer design?
Yes, we manufacture assemblies to your drawing including the magnet grade, steel housing, plating, fasteners and, where needed, magnetization direction and magnetizing fixtures.
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.
What coating options do you recommend for NdFeB magnets?
Nickel (Ni-Cu-Ni) for general indoor use, zinc for cost-sensitive applications, and epoxy or Parylene for environments with humidity, salt or organic solvents. Our QC team can help select the best coating for your operating environment.
