1. Principles of rubber magnets
Rubber magnet is a kind of ferrite magnetic material series. It is made of bonded ferrite magnetic powder and synthetic rubber. It is made of extrusion molding, calendering molding, injection molding and other processes. of the magnet. It can be processed into strips, rolls, sheets, blocks, rings and various complex shapes.
2. The characteristics of original rubber magnets
It has flexibility, elasticity and bendability, and can be produced into rolls, sheets, strips, blocks, rings and various complex shapes through extrusion, calendering, injection, mold forming and other processes. Its surface can also be covered with PVC sheet, coated paper, double-sided tape, coated with UV oil, or cut into various shapes by color printing die.
3. Processing characteristics of rubber magnets
The rubber magnet is composed of magnetic powder (SrO6, Fe2O3), chlorinated polyethylene (CPE) and other additives (EBSO, DOP), etc. It is manufactured by extrusion and calendering. Rubber magnets can be of the same sex or the opposite sex, and can be bent, twisted, or rolled. It can be used without more machining, it can be trimmed to the required size, or it can be coated with PVC, adhesive, UV oil, etc. according to customer requirements. Its magnetic energy product ranges from 0.60 to 1.50 MGOe.
4. The production process of rubber magnets
Batching→mixing→extrusion/calendering/injection molding→processing→magnetization→inspection→packaging
5. Performance inspection of rubber magnets
Appearance, size, magnetic properties, magnetic polarity, hardness, specific gravity, tensile strength, aging resistance, winding performance.
6. Application fields of rubber magnets
Refrigerators, message sign stands, fasteners for fixing objects to metal bodies for advertising, etc., magnets for toys, teaching instruments, switches and sensors. Mainly used in micro motors, refrigerators, disinfection cabinets, kitchen cabinets, toys, stationery, advertising and other industries.
