11.The quality control:we have our large and expert quality control department and we ensure the magnets from our factory are in high quality.

12.We will provide our customers the test report and BH curves for each item magnets,and also we can do the PCT test ,salt spray test report,aging test report and provide the test report  and so on according to our customer's request.

13. We have both our own NdFeB manufactory(covers an area of 11400 square meters and a construction area of 13800 square meters.) in NingBo , also we can assemble the magnetic assembly,we have our own magnetic assembly factory which is about 1 hour away from our NdFeB manufactory in NingBo too. Welcome you come to NingBo to visit our factory anytime.

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.
