Metal injection molding as a morder near net forming technology has been adopted for various of industries,such as automotive,medical,electronic communicationdevices,military,aerospace,
househould appliance accessories,power tools,etc.The reason why more and more enterprises introduce MIM technology to produce the spare parts is its unique superiorities.
MIM superiorities 1: The parts could be designed flexibly
Comparing with other traditional process,the parts with more complex structure could be designed for MIM process,we could say that basically all the structures which could be formed by plastic injection molding would be realized by Metal injection molding,while not sure for other process.
MIM superiorities 2: A wide range of suitable material
Most all the metal material could be used on MIM process,but by considering the cost,usually the MIM material are iron alloy,nickel alloy,brass alloy,stainless steel,tungsten alloy,titanium alloy and other alloy,etc.
MIM superiorities 3: Fine surface finish
The surface roughness of MIM parts could be achieved Ra 0.8μm after magnetic polish,of course,it could get various of beautiful surface by secondary process,such as mirror polish,vacuum electronic plating,blackening,spraying,sand blasting and electrophoresis,etc.
MIM superiorities 4: Tight tolerance
Generally the tolerance of+/-0.3% could be achieved by MIM,but if more precise required,then machining or CNC machining would be used to guarantee.
MIM superiorities 5: Excellent mechanical properities
By sintering under a high temperature of 900-1400 celsius degrees in a vacuum sintering furnace,the powder particles would be condensed and densified to reach a high density of 7.6 at least which is very close to the theoretical density,so the mechanical properties is much better than powder metallurgy process.
MIM superiorities 6: Environmental protection
The ultilization rate of raw material is very close to 100%,so MIM process could effectively avoid the material waste.
MIM superiorities 7: Massive quantity is easy to realize
The production capability could be adjusted timely to meet any quantities needed. No matter hundreds of pieces or millions of pieces could be realized.
