What You Know About Metal Injection Molding And Powder Metallurgy

MIM is well suited for niche applications, but traditional powder metallurgy still offers many benefits for a variety of small powder metal part manufacturing projects.

Understanding the relationship between metal injection molding and traditional powder metallurgy can be helpful when you are deciding which process is right for your needs. Let's look at traditional PM first, since it has been around for a long time.

Basic knowledge of powder metallurgy:

-Start by mixing or blending specific types of metal powders and lubricants.

- Put the mixture into the mold to form a specific shape.

- Use a press to compact the metal powder.

- Sintering of compressed parts in a furnace to form a metallurgical bond in the metal powder.

Large-scale manufacturing of powdered metal parts has been done for over 100 years. It is used to make parts of all different shapes and sizes and is ideal for many automotive and other applications.

Metal Injection Molding Basics:

-Mix the metal powder with a polymer binder to form a viscous solution

-Inject the solution into the molding machine (think toothpaste filled with metal powder injected into the mold cavity.)

- Heating to remove adhesive

- Sintering at high temperature to form a metallurgical bond and densify the powder
