Injection magnet

The definition of plastic injection molding magnets:

Magnetic powder and binder agent is mixed,  granulated, and then after injection molded. This kind of permanent magnet made by this process is called injection molding magnet. It is a magnetic plastic products mainly made up of resin and magnetic powder, resin having adhesive effect, magnetic powder beding the source of magnetism. The magnetic powder is mainly ferrite powder and rare earth permanent magnet powder. Composite magnetic plastic according to the magnetic properties and can be divided into two categories: one kind is easy magnetization direction of the magnetic particles is desultorily, called isotropic magnetic plastics, performance is low, usually by barium ferrite as magnetic materials. Another kind is to exert additional magnetic field and mechanical force, make the easy magnetization direction of the magnetic powder in order, called anisotropic magnetic plastics.

Magnetic plastics, the main advantage is: low density, high impact strength, cutting, cutting, drilling, welding, can be laminated and pressure pattern processing, such as not happen cataclastic when using, it can use generic plastic processing methods (such as injection, molding, extrusion, etc.) for processing, can be processed into a high dimensional accuracy, thin wall and complex shape of the products, you can bring insert molding products, realizes the electromagnetic device miniaturization, lightweight, high motors and performance-based.Get instant prices now
