Metal injection molding (MIM) is a metal working process in which finely-powdered metal is mixed with binder material to create a "feedstock" that is then shaped and solidified using injection molding. The molding process allows high volume, complex parts to be shaped in a single step. After molding, the part undergoes conditioning operations to remove the binder (debinding) and densify the powders. Finished products are small components used in many industries and applications.

MIM consists of different step involving a metal powder and a binder

• Mixing of the two components to obtain a homogeneous feedstock
• Extrusion of the feedstock to obtain pellets
• Melting of the pellets in an extruder
• Injection into a mould of the melt to obtain a green body
• Debinding, to remove the binder from the green body and obtain a brown body
• Sintering of the brown body to a density, today, of 95% of the theoretical density and even more

The typical process control factors for a furnace that are recognized in order to produce good reproducibility of the quality of the sintering parts are the following:

• Measure of the sintering temperature
• Measure of the dew point
• Measure of the oxygen content with an oxygen sensor
• Furnace temperature profile
• Furnace cooling rate
• Furnace atmosphere volume and composition
• Atmosphere location and direction

The sintering process has been divided into three steps-

• First step: Dewaxing to eliminate the lubricant in the green part between 300 °C - 800 °C
• Second step: Sintering at temperature between 1120 and 1250 °C for the formation of solid bridges or necks between the individual powder particles
• Third step: Cooling or rapid cooling to obtain the microstructure and the mechanical properties
