Injection Molded Magnets
Injection molded magnets, often referred to as molded composite magnets, represent a class of advanced materials formed by blending thermoplastic resin with magnetic powder. This unique amalgamation is meticulously processed under pressure, allowing it to flow into a precisely designed mold cavity. Within this cavity, the material takes on its final form, undergoes orientation, experiences a controlled cooling process, and ultimately solidifies into the desired shape. The injection molding process is capable of producing an array of intricate shapes, including thin-walled rings, rods, and complex custom geometries. Additionally, these magnets can be readily combined with other metal components to create versatile assemblies.
Injection molded magnets leverage a range of magnetic powders, including neodymium iron boron (NdFeB), samarium cobalt (SmCo), and ferrite, in conjunction with thermoplastic resins such as PA6, PA12, and PPS.
