Powder injection molding manufacturer ZCMIM
(http://www.sky-mim.com/about-us.html) gives you a brief description about
basic producing processes of powder metallurgy. The first is the preparation of
raw material powder, the current powder metallurgical milling methods are
mainly mechanical method and physical-chemical method.
Wherein physical-chemical method, it can be divided into reduction
method, compound method and electrolysis method. Using powder to form desired
shape , the main purpose is made a certain shape and size. And it has a certain
density and strength. Molding methods can basically be divided into
non-pressure molding and compression forming.
Sintered is the most critical process in powder metallurgy
technology. Molding blanks can obtain the final desired mechanical properties
after sintering. Sintering temperature should be slightly lower than the melting
point of metals and alloys. Sintering some alloys, wherein the control
temperature is lower than the melting point of its refractory component, but
above the melting point of fusible components. The final step is forming. By machining
to process gears as desired.
