Metal injection molding is a technique of making metal parts, which uses a powder metallurgy process. Metal injection molding requires the metal powder that is 10-100 times smaller in size, compared with the metal powder. The end product in the case of metal injection molding has a higher density.
This technique is often used by manufacturers like redstonemanufacturing to produce surgical tools, firearm components, hard disk drives for computers, electrical connectors, and automotive keys.
This process consists of five steps, which include mixing, injection molding, de-binding, sintering, and finishing section. This process is becoming more popular day by day.

The first step involves mixing metal powders. They have inherent characteristics, such as high impact strength, wear resistance, hardness, machine capability, and temperature resistance.
As a result of mixing the powder, we get what is known as a raw material, which is injected into a mold. Phase de-binding involves soaking the green parts in baths of water to get rid of the fastener that has gone on the matrix.
After the binding phase is over, the components are heated to a temperature above 2000 ° Fahrenheit in the furnace. This process is known as sintering and fusing metal parts to give them a solid form.
Ultimately, the sintered component is sent to the finishing stages to eliminate imperfections and burrs. This is a very good technology when we want components that have complex shapes and characteristics.
This process is ideally used for the manufacture of microelectronic packaging, actuators, and sensors for the automotive, hardware, hand tools, heat dissipation devices for computers, oil drilling tools, engine fuel parts, and more.
