1. What are Injection Molded Magnets?
Injection molded magnets are essentially dense magnetic powder mixed with various plastic polymer materials. According to the choice of mixing different magnetic materials and plastic polymers, a variety of different material properties can be obtained in the end. Choosing the right combination can affect a product's resistance to moisture absorption, physical strength, magnetism and even maximum operating temperature. Injection molded magnets can be manufactured in very simple or very complex shapes. Depending on the specific magnetic material, the magnets can be magnetically oriented during the injection molding process to optimize magnetic properties.
With both rigidity and elasticity, it can be processed into thin-walled rings, rods, sheets and various special and complicated shapes; it can make magnets and other metal inserts (gears, screws, special-shaped holes, etc.) in one time molding, and cracks are not easy to occur, Fracture; the magnet does not require mechanical processing such as cutting, the product yield is high, the tolerance precision after molding is high, and the surface is smooth; the magnet has good internal uniformity, good surface magnetic field consistency, and strong corrosion resistance.
2. Injection Molded Magnets Feature:
The characteristic of an injection molding magnet is that it can not only be magnetized in the axial direction, but also can be magnetized in multiple stages in the radial direction, and it can also be magnetized in the axial and radial directions. The appearance of the product is smooth and flawless, with high dimensional accuracy, good consistency, subsequent processing, stable performance, shock and impact resistance, and the product can be complicated. It is an indispensable signal source and constant magnetic source for the micro-motor and automation industries. It has other magnets that cannot be replaced. and analogy.
With hardness and elasticity, it is easy to process into thin rings. It can be injection molded together with the shaft to simplify assembly and ensure precision. Complex shapes and precise tolerances can be achieved. In the case of heating and melting, they have a uniform density and good consistency. They are produced by injection from a mixture of ferrite powder and plastic binder. Excellent corrosion resistance due to ferrite powder covered by plastic binder

4. Injection Molded Magnets Advantage:
The appearance is smooth and flawless, with high dimensional accuracy, good consistency, no need for subsequent processing, stable performance, shock resistance and impact resistance. The main function of the magnetic ring on the walking wheel of the sweeping robot is to control the motor speed and steering.
Overmolding and insert molding with other parts (e.g. back yokes, hubs, axles) is readily available, and injection-molded other polymer parts can also be incorporated.
Injection molded magnets have a higher volume fraction of polyester binder than compression molded magnets. In most applications, it will provide adequate corrosion protection without the need for a coating.
