Product Description
Polymer bonded magnets opened a new world of application opportunities. The processing temperatures to blend and mold the material mixture is low enough to allow many different magnet powders to be used alone or in combination in the polymer binder to achieve an unprecedented range of properties.

Another benefit of the injection molding process is that magnet material can be directly molded into, onto, or against other assembly components eliminating subsequent assembly steps. This is called insert injection molding.

Injection molded magnets can be formed from very simple shapes to very complex shapes. All or only part of the device may be magnetized. Often, it is cost advantageous to make an entire part out of the magnet material and magnetize only the portion requiring magnetic output. - See more at:
Product Feature
Polymer binders utilized by Flexmag's Plastiform product include nylons 6 and 12 and PPS (polyphenylene sulfide). Binder evaluations are a continuous activity in the Development Laboratory, in an effort to improve physical strength, maximum recommended use temperature, improved corrosion resistance for the rare earth magnetic materials, improved dimensional stability in the presence of water and solvents, and greater ease of processing. - See more at:

An important characteristic of injection molded magnets is that they conform dimensionally to the mold cavity which is precisely machined, the result being close tolerances in the finished product. What little dimensional variability there is results from shrinkage of the polymer during cooling. This depends upon part thickness and shape. Typical tolerances are +/-0.003 in/in. Closer tolerances on critical dimensions can be negotiated. - See more at:
Product Specification / Models
Injection molded magnets can be available using ferrite , neodymium-iron-born , or blends of magnetic materials to achieve an extensive range of properties,produced from very simple forms to quite complex shapes in sizes with high precision, typically ,tolerance is +/-0.005mm, suitable for high precision parts.

It is a new technology to achieve adjustable magnetic properties, composite molding, elastic magnetization and high mechanical strength. By doing insert molding, magnetic material can be directly molded into or onto other assembly components without further assembly process.

Application / Models
The parts widely used in permanent magnetism DC machine, magnetic stepping motor, control motor, meter motor, air-conditioner fan electro-motor, printer magnetic roller, printer, decoder, coder selection loudspeakers and many other special applications.
