Injection Molded Ferrite Servo Motor Rotor

Injection Molded Ferrite Servo Motor Rotor

Injection molding ferrite is a composite of ferrite or NdFeB magnetic powder, plastic (such as nylon, PPS) and other materials. It is a functional magnet that can be embedded in metal bodies and plastic bodies made by injection molding technology. It has high dimensional accuracy, The advantages of complex shape and high toughness. The products are mainly used in permanent magnet DC motors, stepper motors, instrument motors, electronic products, home appliances, printers and copier magnetic rollers, etc.

The main advantages of injection molded magnets are: low density, high impact resistance, can be processed by cutting, cutting, drilling, grinding, lamination and embossing, and will not break when used. It can be used in general plastics Processing methods (such as injection, molding, extrusion, etc.) can be processed into products with high dimensional accuracy, thin walls and complex shapes, and products with inserts can be formed to realize the miniaturization, light weight, precision and high performance.

Advantages of Injection Molded Ferrite Magnets:

Compared with other manufacturing methods of permanent magnets, injection molding has unique and irreplaceable advantages.

1. Like plastic products, injection molding can make magnets with complex shapes; molded parts can have unique size, shape, magnetic and mechanical properties;

2. The injection molding process can use "embedded molding", "multi-step molding" and "multi-part molding" to combine magnets with other parts, thus saving the cost of secondary processing and assembly;

3. Injection molding technology can produce both isotropic and anisotropic magnets. Anisotropic magnets require an external orientation magnetic field during molding, so that the magnetic powder has a certain orientation in the polymer in the molten state, that is, orientation occurs, and multi-pole magnetization can be realized;

4. The injection molding process makes the product have better consistency in size and performance, and the product shape is diverse;

5. Due to the high content of polymer binder in the injection molded magnet, the magnet itself has strong corrosion resistance and usually does not need surface coating protection;

6. High-strength magnetism and excellent mechanical properties;

7. Compared with sintered magnets, injection molded magnets have better crack resistance and are easier to assemble; the in-line molding process can directly inject magnetic powder onto the product to form components;

8. The magnet can be fully magnetized, or partially magnetized and demagnetized;

9. The adhesive and magnet used can meet the application temperature from -40℃ to 180℃.

The company has its own plastic magnetic mold manufacturing workshop, and develops corresponding injection molds according to the design drawings of magnetic components required by customers. Precise mold processing equipment produces precise injection molds and precise plastic magnetic products.
