Bonded Mould Injection NdFeB

Injection Plastic NdFeB magnet is a kind of new generation composite material made from permanent magnetic powder and plastic. Injection NdFeB powder is blended with a plastic material and injection molded. With High precision of size, it can be made into complex shapes and also be bonded with other components. The injection molding magnet can be magnetized in any directions and with multiple poles.

National neodymium hook magnets are made using strong rare earth neodymium magnets, and are housed in a nickel finished steel cup. This cup serves a dual purpose of both protecting the magnet from damage while maximizing the magnet’s overall grip strength. The utility of these magnets comes via the attached hook which allows for the hanging of objects without permanent fixation.
