The differences between MIM (metal injection molding) parts and forged parts primarily lie in their process principles,
applicable scenarios, and product characteristics:
Process Principle
MIM involves mixing metal powder with a binder and then injecting it into a mold. Parts are then produced through processes such as degreasing and sintering. This is a near-net-shape technology. Forging, on the other hand, involves applying external forces to plastically deform a metal material to form the desired shape.
Application Scenarios
MIM is suitable for producing complex three-dimensional parts (such as mobile phone card trays), achieving an accuracy of ±0.1% to 0.5%. However, it is not suitable for large structural parts (such as mobile phone midframes). Forging is commonly used to produce large parts (such as automotive parts), but it struggles with complex and precise structures.
Product Characteristics
MIM parts can achieve a surface roughness of 1 to 5 μm and a density exceeding 95%, but can suffer from shrinkage deformation. Forged parts have a dense structure and excellent mechanical properties, but are prone to cracking when processing complex structures.
Of course, there are obvious differences between these two metal forming processes. You should choose the appropriate metal processing process according to different application scenarios.
