Mini bonded Nd-Fe-B magnets
We are specialized in manufacturing bonded Nd-Fe-B magnets. We have been supplying the market with excellent quality products and services in competitive prices for years, and have earned well appraisement. expert knowledge, years of experience and modern plant enable us to offer:
Various specifications
full range of different shapes (such as arcs, rings, or others meeting your needs)
High magnetic stability
Excellent size tolerance
Good mechanical strength
sprayed epoxy coatings, electrophoretic epoxy coatings and CVD parylene coatings available, this can make the surfaces of our products glossy, dense, rustproof and no flaking.
multi-pole planar/radial poling
complete customer-oriented designing and manufacturing
excellent quality through quality management
our products have been widely used in stepper motors, Micro Motors, Dashboard Instruments, Peripheral Computer Equipment, medical instruments, Sensor Magnets, clocks & watches, household appliance, etc.
We have manufactured mini bonded Nd-Fe-B magnets for many years. These mini-magnets have excellent size tolerance, stability performance. parylene coating can make these products rustproof.
