Metal Injection Molding, abbreviated as MIM, is a method that mixes metal powder and binders for injection molding.
Fine Powder:
Powder particle size D90 less than 40um
Narrow particle size distribution
High Volume Ratio of Binder:
Binder volume ratio up to 45%
Multiple binder systems of metal injection molding to meet different molding characteristics requirements
Feedstock, made by mixing metal powder and binder
High Rate Molding:
High mold accuracy
Equipped with specialized injection molding machines
Sintering Technology:
Solid phase sintering or liquid phase sintering
Different types of sintering equipment
Metal phase diagrams
Materials science knowledge
Ability to produce complex-shaped parts
Parts produced have characteristics of high precision and high density
Allows for mass production with high production efficiency
High raw material utilization
Wide material applicability
Metal materials with a high melting point
Above 1100℃, such as iron, nickel, titanium, cobalt, copper, tungsten, and molybdenum-based alloys
Materials that are difficult to machine
Parts with complex structural designs that are hard to produce using stamping, precision punching, cold heading, machining, or traditional powder metallurgy
Structural or micro features that are hard to achieve by casting
Dimensional accuracy can be achieved using standard injection molds and MIM processes; secondary processing can be used if necessary to meet the linear dimensional tolerance of the M class as per GB1804-2011.
High surface appearance requirements; MIM parts generally achieve a surface roughness of Ra3.2um, with subsequent treatment possible
Mixing selected powder with binder
Depositing and injection molding the mixture into the desired shape
Removing the binder through debinding and sintering processes
Post-molding treatments such as surface treatment, heat treatment, and machining
