High Precision Micro Magnet

High Precision Micro Magnet

Particularly adept in tiny and accurate parts, able to machine the size beyond 1mm, and accuracy is within 2 to 5 μm. Moreover, We also technically handles surfaces of magnetic materials with plating and chemical-plating. The products are widely applied to the fields of automobile, motor ,optic communications,watch movement, meter and sensor,and getting high reputation overseas (Switzerland, Japan,HongKong, USA, Korea, Italy etc).

We own advanced processing equipments and full set of production lines, products range can be as small as size class, 0.2 mm ~ 2.0mm, with high precision, tolerance between 0.005mm and 0.02mm. Also, we can make thickness 0.12 mm on very tiny thin ring like magnetic materials, using high electroplating technology like parylene coating and checkout equipment of projector and microscope to offer high and reliable products for our customers.

We have the ability to make small neodymium micro magnets less than 0.2 mm. Our tiny micro magnets have been used in many consumer electronics and medical applications. We carry many sizes of neodymium micro magnets in stock, but If you require a small, tiny neodymium micro magnet in a custom size, please contact us or use our online custom magnet quote form.

Product application:

HSMAG Magnet is famous for our micro magnet parts, especially applied in micro motors, computers, communications equipment, instruments and meters, clocks and watches, speakers, home appliances, medical equipment, aerospace, military and optical fiber and other fields.

Magnet Materials:

Oftentimes ultra-small magnets are limited to bonded magnetic products, but now HSMAG can deliver miniature, fully dense Neodymium Iron Boron (Neo), Samarium Cobalt (SmCo), and Strontium Ferrite (Ceramic). In addition, HSMAG can supply miniature cast Aluminum Nickel Cobalt (Alnico) magnets, a magnet alloy that has been traditionally been limited in non-micro sizes.

Environmental Protection:

As well as manufacturing a variety of small magnet solutions, HSMAG Magnets can provide an array of coating or plating options. Conventional magnet corrosion inhibiting solutions can be applied such as Nickel and Epoxy but also Parylene C which is oftentimes used for its inertness when the magnet will be exposed to an organic environment.

(Please note–As with larger magnets, the penetration of a corrosion inhibiting layer is limited inside small holes and features.)

Geometries:

All shapes and available, Discs, Blocks, Rings, Arcs, and Spheres as well as custom geometries. What is especially beneficial to the market is HSMAG’s deep hole capability. This is where the hole length is greater than the diameter of the part.
