MIM Process Advantages


MIM process advantage 1: extremely high design freedom
Compared with other metal forming methods, MIM can manufacture parts with more complicated shapes. Basically, all the structures that can be achieved by injection molds can be applied to MIM.
MIM process advantage 2: more material choices
MIM can use most metal materials. Considering economy, the main application materials include iron-based, nickel-based, copper-based, titanium-based metals or alloys.
MIM process advantage 3: excellent physical and chemical properties
Because the sintered density is very close to the theoretical density, the physical and chemical performance of MIM is also very good, such as mechanical strength, which greatly surpasses traditional powder metallurgy.
MIM process advantage 4: exquisite appearance
The surface roughness (Ra) of the MIM sintered blank can be 1 μm, and it can also obtain a dazzling appearance effect through various surface treatment methods.
MIM process advantage 5: higher dimensional accuracy
MIM can generally achieve a tolerance accuracy of ± 0.5%. With other processing methods, higher dimensional accuracy can be obtained.
MIM process advantage 6: strong and flexible mass production capacity
MIM can flexibly adjust and quickly increase production, from a few hundred pieces per day to more than hundreds of thousands per day to respond quickly.
MIM Process Advantage 7: Environmentally Friendly Processing Concept
The raw material utilization rate is close to 100%, which is a near-net forming technology that can effectively avoid material waste.



MIM products usually have the following characteristics

The most suitable wall thickness for MIM is no more than 6mm. Thicker outer wall is acceptable, but the cost will be increased due to the longer processing time and extra material used. In addition, u



What is the density and strength of MIM products?

The density of a typical MIM is theoretically higher than 98%. Specific density characteristics depend on the choice of material, but it is very close to precision materials.





Metal injection molding technology in detail

Metal injection molding (referred to as MIM) is a technology combining powder metallurgy and injection molding, which breaks through the traditional powder metallurgy product shape and strength limitations, also breaks through the strength limitations of die casting, breaks through the material flow restrictions of stamping molds, and breaks through precision. Mass production restrictions for casting and high cost constraints for turned parts.



The market competition pattern of 3D printed metal powder may change

The market competition pattern of 3D printing metal powder will change as more companies enter or increase their production and R & D efforts in the field of metal powder. In 2016, GKN, Oerlikon and Alcoa made active strategic plans.



Rich variety of raw materials, and the variety of domestic powder metallurgy products has been expanded

In terms of raw materials, at present, the main raw materials of powder metallurgy in China are not only reduced iron powder, electrolytic copper powder, etc., and domestic production of atomized iron powder, stainless steel powder, high-speed steel powder, coated powder and various element metal MIM powder, Ceramic powders can basically meet the needs of domestic production of high-strength parts, and can also produce raw material powders for special purposes, which greatly expands the variety of powder metallurgy products, but there is still a large gap in quality and variety from abroad.
