High Precision Pinion Steel Rack

By comparing with other traditional metal forming technology, we could know that there are many superiorities on MIM technology.

1, Building the mold by one time to realize massive production.
2, The precise mold could guarantee the quality of each products.
3, Basically no need to do any secondary machining, just as many assembled items made by other traditional process, it could be formed by MIM technology by one time.
4, The products could get a pretty high density 7.6-7.8g/cm3, so it is no need to do resin sealing before any plating.
5, The surface roughness is good, it could reach Ra 1.6 um after magnetic polishing.
6, The porosity on MIM products is pretty small and the surface is very smooth, because the size of raw material powder is pretty small (less than 25um).
7, It is very suitable to produce the products with high complexity structure.
8, A pretty wide range high strength alloy material could be used on MIM technology.
9, The raw material utilization could reach 98%, so basically no any waste.

10, The forming theory is the same as Plastic Injection Molding, any complex structure is feasible.

So the more complex the products structure, the more suitable to use Metal Injection Molding(MIM) technology.
