China HANGSENG MAGNETECH LTD. specializes in custom NdFeB magnets, SmCo magnets, Alnico magnets, Ceramic magnets, Rubber magnets,etc.
Some common applications custom include:
Arc magnets
Motor magnets
High temperature magnets
Rubber Strip Magnet
Adhesive magnets
Molded magnets

If you need a custom magnet to your exact specifications, you have come to the right place. We can do short run, and large volume production runs.
We do not have minimum orders for custom magnets, however pricing will be reflective of the quantity purchased due to startup and production costs.
We will need all of the following information when quoting your special order magnets.

Exact Dimensions: We will need clear accurate drawings, which show all critical dimensions as well as the direction of magnetization. Please use PDF, DXF, JPG, BMP or TIFF formats.
Magnet Grade: Please indicated the grade of magnet (N40, 42SH etc) See Grade Chart
Magnet Type: Please indicate the type of magnet you wish quoted. (NdFeB, AlNiCo, SmCo, Ferrite)
What is the desired working temperature?
Quantity: What will be your initial requirement? What will be your monthly/yearly needs for this same product?
Time: When do you need this by? Normal custom magnet prototyping is 3-4 weeks. Please send your special and custom magnet requests to
