Iron-based powder is an iron-based powder metallurgy, carbide-based powder is WC, TIC and other production processes are basically the same, the mixed powder - molding - sintering - after the order processing - inspection - package but will not process parameters same.


Iron-based plastic in order to reach a certain size requirements or face type requires additional steps, because the springback forming great iron-based products, general product after forming the outer diameter of the sintered dimensional change is large. The same batch, the inner diameter size, or height do not necessarily meet the requirements of the final product, and then design process by shaping to size and height requirements. general requirements for tight tolerance products.


Mixed powder and powder particle major size and shape and other relevant. There is alloying elements and a lubricant and a binder.


Molding is press tonnage, mold design, and other related.


Sintering is the relevant process parameters sintering temperature, sintering time and sintering atmosphere was like.


Then that some post-processing. Machining, heat treatment (quenching and tempering), surface carburizing.
