Rubber coated magnets are mainly composed of permanent magnets, steel back plate and rubber part. Similar to pot magnets, rubber coated magnets have far stronger holding force than a same-sized plain magnet. With rubber coating, the friction between contacting surfaces are significantly increased, which also provides a better shear force. Besides, the rubber can protect the contacting surface against scratching.
Magnets are the core of rubber coated magnets. Generally, the magnets are in disc shape and they are fitted on the steel plate in an alternating-pole configuration. The alternating-pole arrangement forms special magnetic circuits on the working face of the magnetic assembly, which can significantly enhances the magnetic strength. After installing the disc magnets onto the ferromagnetic steel plate, the assembly is fitted into an injection molded rubber base. The rubber based is then placed in a mold. Followed by an overmolding process, the magnetic assembly is encapsulated by the rubber.
