Magnetic Alloy

What Is Magnetic Alloys In Metal Injection Molding

Magnetic Alloy Metal Injection Molding (MIM) is a cutting-edge manufacturing process offered by Neway that combines the versatility of plastic injection molding with the superior properties of magnetic alloys. It involves finely powdered MIM magnetic alloy materials, such as MIM-Fe-50Ni, MIM-Fe-3Si, and MIM-Fe-50Co, mixed with a binder to form a feedstock. This feedstock is then injected into molds with high precision. After shaping, the components undergo a debinding and sintering to achieve their final metallic form. MIM enables intricate geometries, exceptional magnetic characteristics, and high production efficiency, making it an ideal solution for various industries.
