Customed Big Size Steel Parts By MIM

Metal Injection Molding(MIM) technology is very suitable for the small and high precise structures components production, but not very suitable for the big structures and big weights components, the reasons as below:

1) The sintering cost is very high, since the bigger the components structures, the smaller the sintering quantity we could place into one sintering furnace, so the everage sintering cost rises.

2) It is very difficult remove the debinder completely in degreasing operation,generally 98% debinder could be removed after the degreasing operations, but for the big structures components, 98% is very difficult, so it would afftect the later sintering processing.

3) It is hard to control the dimensions shrinkage during the sintering processing, since the bigger the dimensions, the bigger the shrinking happened, so the dimension tolerance could not be controlled well.

We Shandong No2 Machinery Company developed 4 big MIM parts with the material stainless steel SS17-4PH successfully for Huawei Group China, the parts weights ranges from 600grams to 650 grams, while it is very difficult for another Metal Injection Molding(MIM) manufacturers to do.
