What are flexible magnets made of?
Flexible magnets (also called rubber magnets, soft magnets, bendable magnets, bendy magnets) are made of strontium ferrite powder compounded with plastics or rubbers (NBB or CPE). The main 3 grades of flexible magnets are Isotropic, semi-anisotropic, anisotropic, although the magnetic properties with (BH)max from 0.6 MGOe to 1.6 MGOe.
Flexible magnet tools are flexible and soft like their name, and they can easily be cut to the shape/size required using a knife, also easily bent, twisted, slit, or coiled. No loss of magnetic properties will happen during this. As a reputable magnet factory, RiSheng provides customised flexible magnets based on different materials, such as small flexible fridge magnets, strong flexible neodymium magnets, small size flexible magnets, etc. RiSheng is one of the most professional flexible magnets manufacturers in China that can also provide you with neodymium flexible magnetic sheets and flexible neodymium magnetic tapes.

Manufacturing method of Flexible Magnets
The main production ways of flexible magnets are: calendering for magnetic sheet and extrusion for magnetic tape, the standard magnetizing method is multiple poles magnetized on a single face with magnetic pitch 1.5mm, 2mm, 2.5mm, 3.0mm, or 5.0mm. Though magnetized thru thickness is also possible for a magnetic sheet if it is required for special applications, there will be a single pole on each face.
The non-magnetic face can be plain or laminated with PVC, self-adhesive, dry-wipe PET, PP for different usage, while the magnetic face is generally with UV coating.
Applications of Flexible Magnets
Flexible magnets are widely used in various commercial and industrial applications, mainly for automotive signs, business cards, commercial signage, crafting projects, DIY home improvement, fridge magnets, large format graphics, name badge holders, office presentations, packaging closures, paint masking applications, POP & trade show displays, promotional giveaways, warehouse labelling, windows & door seals.
How are Flexible Magnets made?
In the manufacturing process of magnets, the first step is casting. First, put flexible magnet materials into the electromagnetic furnace, melt all the metals into liquid, and then pour the liquid into the mould to create the approximate shape of the magnet. However, the flexible ferrite magnet at this time has no magnetism.
You need to make the magnet magnetic. The second step is to energize. Tie the magnet to the copper tube, put it into a larger tube, and then charge it with high-voltage electricity. At this time, the electrons in the magnet will flow slowly from the positive pole to the negative pole with the current, resulting in certain conversion efficiency of the electrons on both sides. Precisely, after this step is completed, the strong flexible magnet will have magnetism.
