What is injection molded magnet?

Injection molding magnetic ring, is the magnetic particle inspection and adhesive mixing glue granulation, then through the injection molding process made of permanent magnet is called injection magnet. Compared with other permanent magnets, injection molding has unique and irreplaceable advantages.

Basic principle of injection molding

Plastic injection molding is a second magnetic magnetic ring forming method, also known as injection molding, is a polymer composition of the filler or granular material into the injection machine cylinder, by heating, narrow, cutting, mixing and transportation efficiency, make the material proportion and melting, then with the plunger pump or extruder screw to molten polymer melt pressure, The high-temperature solution is injected into the pre-closed ultra-low temperature mold core according to the spout and the spate system software of the die casting mold. Finally, the mold shell is opened to obtain a certain geometric shape and precision of the product.

3 ferrite plastic magnetic injection molding advantages

As with plastics, injection molding can be used to create magnets with more complex designs. In addition, the injection molding process can choose "embedded molding", "multi-step", "multi-product workpiece molding" method to integrate the magnet and other parts, thus saving the cost of secondary production processing assembly.

Injection molding technology can produce both anisotropic magnets and various magnets. All kinds of magnets must be added to the trend electromagnetic field when forming, so that magnetic particle flaw detection in the molten state of the polymer has a certain orientation, that is, to produce trend, and can complete the multipole magnetization. The injection molding process promotes good uniformity in size and function.
