Plastic Bonded Pressed Magnets / Plastic Bonded Magnets
Plastic bonded pressed magnets are the result of the union between thermoplastic binders and permanent magnet powders, and can be made in isotropic or anisotropic qualities.
Pressed magnets are magnetic products manufactured with high precision and tailored for each application.
Type of material
Magnetic powders: ferrite or rare earth / Thermoplastics
Composition
NdFeB / SmCo
Ferrite
PA6 / PA11 / PA12
Work temperature
From 100ºC to 120ºC
Advantages
Good mechanical properties
Creation of complex shapes
