INJECTION MOLDED MAGNETS

Injection molded magnets are available using ferrite, neodymium-iron-boron, or blends of magnetic materials to achieve an extensive range of properties. Binder types include Nylon 6 and 12, PPS, and Polyamide. The binders and magnetic alloys are capable of a wide range of application temperatures from below -40°C to above 180°C. The Injection molding process is particularly well suited to molding very intricate shapes and thin walled parts. The finished parts can be either very simple or complex in geometry.

Magnetic materials can be insert injection molded directly inside or against an existing component to produce assembly pieces. Injection molded magnets dimensionally conform to mold cavities, which are precisely machined, resulting in finished products which usually do not require further finishing operations. This eliminates subsequent operations and reduces total cost.
