Magnetic Injection Molding

Magnetic injection molding offers a greater variety of shapes and more complex shapes. The injection molding process allows for overmolding. Injection molded magnets produce tens or hundreds of thousands of magnets per production run. Magnetic materials are incorporated into the product during the manufacturing process. By adding magnetic particles to the plastic or using magnetic plastic, the product is made magnetic.

In the field of electronic products, magnetic injection molding can be used to produce magnetic housings, brackets and other parts. This provides more flexible design options for the assembly of electronic devices while increasing the magnetic functionality of the product. For example, by producing cell phone cases with magnetic adsorption functions, users can easily attach their cell phones to magnetic surfaces.

In the field of medical devices, magnetic injection molding can be used to produce medical devices such as magnetic catheters and stents. It helps improve the guidance and controllability of medical devices, making surgical procedures more precise and safer. For example, by using magnetic catheters, doctors can more accurately guide the catheter to the target location, reducing surgical risks.

In the automotive industry, our products can be used to manufacture magnetic auto parts such as magnetic navigation brackets, in-car storage boxes, etc. The addition of these magnetic features not only improves the practicality of automotive parts, but also provides automotive designers with more room for innovation.

For example:

A company needed a ring magnet with multiple poles around its circumference for rotational motion sensing. Injection-molded ferrite magnets are magnetized using a special magnetizing fixture to create the desired multipole pattern. The ring also has a groove for mounting over the keyway on the shaft to lock into place in the assembly.
