A variety of ferrite powders, nylon 6, nylon 12, polypropylene, and other resins can be combined to create ferrite-bonded magnets through injection molding. There are numerous classes available based on magnetic performance, temperature resistance, and mechanical strength, as there are countless possible ratios between magnetic particles and resins. These materials can be molded directly over or into a metal or polymer component. The possibilities for magnetization patterns are limitless, either in the molding tool or using a magnetizing fixture, allowing for various shapes and sizes. The tables below include a few popular grades, but we can formulate any required grade of magnetic material based on the customer's specifications.

001-Injected Ferrite Magnet

Injection molded magnets are available using ferrite, neodymium-iron-boron, SmCo, and SmFeN, offering a wide range of magnetic characteristics. Examples of binder materials include nylon 6, nylon 12, and PPS. The application temperature can vary from -40 degree to 150 degree , depending on the binder and magnetic alloy combinations.

The injection molding method allows for the molding of complex shapes and thin-walled items. This means that magnets and magnetic systems can now include thin rings, mechanically non-magnetized details, and more. Additionally, the magnet can be insert-molded over a metallic or polymer component, or it can be molded over with regular plastic, allowing for the production of the full assembly in one or two processes.

1. Isotropic magnets (tools with no magnetic field): ferrite and NdFeB.

2. Anisotropic magnets (axial, diametral, radial) created by electromagnet(s) in the tool: Ferrite, NdFeB, SmCo, SmFeN.

3. Polar anisotropy generated by permanent magnets in the tool: Ferrite.
