Powerful Magnetic Door Catcher

HSMAG Magnets can offer both sintered NdFeB magnets and magnet assemblies. All our NdFeB material is manufactured at our factory in Ulvila, Finland. We are focused on the production of big magnets, axial flux machine magnets and very small magnets for sensor applications. Our coating options include for example nickel, tin and epoxy.

Magnet assemblies, for example pole elements for large electric machines, are manufactured at our factories in Finland and in China. For magnetizing, handling and measuring large-scale magnet systems we have special equipment. 

In addition to NdFeB permanent magnets, we can supply SmCo, AlNiCo and ferrite magnets sourced by our subsidiary in China. Furthermore, we can offer technology and consulting services related to permanent magnets.

Testing Center

We are ISO/TS16949:2002 certified and well implement all procedures strictly under control. Problem preventive actions and quality assurance are preoperly combined with special inspection for all procedures from raw material purchasing ,outside cooperating part manufacturing,inside manufacturing to shipping . We also install a complete set of physical and chemical test equipment to make sure that all our products are manufactured and shipped under strictly quality control .

Salt Spray Test :

Mainly test the surface treatment against the corrosion.  Usually the tested samples will be  continuous sprayed 24 hours in the 35℃ temperature to see if there is any rust appearance on the surface. 

Projection Instrument:

Mainly test the magnets with irregular shapes such as arc segments and any other irregular-shaped parts to see if their dimensions meet the customers' requirements or not.  

PCT Instrument:

Mainly test the magnets to prevent against corrosion on the high temperature and high atmospheric pressure . Usually the test condition is 120℃ temperature and 2 atmospheric pressure .

Heat& Humidity Instrument:

Mainly test the magnet to against corrosion on certain temperature and humidity . Usually the test condition is 80℃ temperature and 90%+/-3% humidity

Hysteresgraph:

Mainly test the magnetic characteristics of the magnet, including Residual (Br ), Coercive(Hcb) . Intrinsic  Coercive(Hcj), Max. Energy product(BH max) and any other related magnetic parameters.
