1. Feedstock CompoundingMetal injection molding can use a variety of materials and alloys. Check out our MIM Materials List of available options. Production begins with mixing exclusive metal powder and binder raw materials. Granular feedstock ensures optimal material flow and processing. Precise control ensures consistency. Common materials used in metal injection molding include stainless steel, titanium, and aluminum. The Metal Injection Molding Materials List provides detailed information on each option's properties and applications. |

2. Metal Injection MoldingMetal injection molding materials are processed by fully automatic metal injection molding machines, heated and injected into tools or molds with multiple complex cavities at high speed. Once the molded metal is formed, the result is called the "green part." Due to the addition of additional binder, the green part is approximately 20% larger than its final size, causing shrinkage during debinding and sintering. Once the green body is produced, it goes through a debinding process to remove the binder and is then sintered to achieve final dimensions and properties. |

3. Debinding ProcessThe formed metal parts then undergo the first stage of degreasing. The binder system used in the raw material formulation for metal injection molding undergoes a two-step degreasing process. Although there are many degreasing methods, there are currently two main degreasing methods used by metal injection molding companies: catalytic method and solvent method. Catalytic debinding uses vapor-phase nitric acid to remove some of the binder, while solvent debinding systems soak green parts in solvent for several hours to remove most, but not all, of the binder in preparation for sintering. Once this process is complete, the part is called a "brown part." |

4. MIM SinteringThe MIM sintering stage involves placing brown parts produced by amorphous metal injection molding into a high-temperature furnace. By heating the molded metal part close to its melting point, any remaining adhesive is completely removed and the metal particles bond together. The part then shrinks and densifies, developing the final strength and geometry of the metal part. |

5.Inspection and Secondary OperationsAfter sintering, metal parts manufactured by liquid metal injection molding can undergo additional operations to improve dimensional control, achieve tighter tolerances, improve mechanical properties and visual appearance, such as heat treatments and coatings. These are called secondary operations and can be performed within the MIM factory. Finished MIM parts are manufactured to approximately 98% of the theoretical density of the wrought metal and therefore have similar mechanical properties. |
