[Q1] what is injection molding magnet/Plastic magnets?
[A1] injection magnet is a mixture of magnetic powders of NdFeB or ferrite with plastic material (PA6, PA12, PPS, etc.) and other materials and produded through injection molding processing .
[Q2] what about the magnetic force of injection magnets?
[A2]The magnetic force of injection ferrite magnet is weaker than that anisotropic ferrite, stronger than that of isotropic ferrite.
The magnetic force of injection NdFeB magnet is weaker than sintered neodymium magnets,stronger than anisotropic ferrite magnets.
[Q3] how strong for magnetic surface value in Gauss?
[A3] Generally the magnetic flux of the injection ferrite magnet is about 1200-1300Gs, up to 1500-1600Gs and injection ndfeb magnets can reach 2000Gs, the detail is depending on the product size and magnetizing way.
[Q4] does injection magnet need to build mould ?
[A4] Yes, Plastic injection magnet must be molded for each size magnets, so we can only produce samples and bulk magnets with mold, Super Magnet Co.,Ltd can provide the injection magnet mold design and mold production services.
[Q5] what advantages does injection magnets have?
[A5] The plastic magnet has the advantages of accurate size, light weight, thin wall, complex shape, complex magnetization and stable magnetic properties. It can be overmolded with other metal parts directly.
[Q6] Which products are mainly used for injection molding magnets?
[A6] injection magnets are used in wide application including hall sensors, pump, automotive air conditioning fan motors, automotive instruments, brushless motors, etc.
