Brief introduction of Metal Powder Pressing Molds of the relevant knowledge

Oct 13, 2017

Speaking of Metal Powder Pressing Molds, popular to introduce, we actually pay attention to it is to a large extent, in fact, it will be directly put the metal powder directly into the special pressure die The cavity to go, followed by, to its extent, in fact, is to die by punching the powder for the metal powder molding method.


Metal Powder Pressing Molds of the stamping, it is in a very large extent, it will be for the steel film. In the case of its repression, the main reason for its pressing pressure is its frictional force and its external friction.


However, on the other side, we actually have to pay attention to its powder particles in fact, there will be a direct internal friction and the powder particles and die wall between the external friction phenomenon, in view of this, Its resulting flat density distribution uneven, when it comes to its performance, in fact, refers to the use of one-way suppression of the time, on the relatively small part of the density from the die punch is relatively high, On its part of the farther, we actually have to pay attention to it in terms of density is actually relatively low.


Then, on the Metal Powder Pressing Molds, the height of its green compact and diameter ratio is relatively large, for its upper and lower density difference is actually relatively large, on this point, that is, to pay attention Can use two-way suppression method. Of course, in order to make the density distribution of flattened more uniform, it is necessary to pay attention to the use of friction with the core of the die to be pressed.


Finally, on the Metal Powder Pressing Molds, in terms of its powder particles in terms of the fact that there will be a direct internal friction, and its powder particles and die wall in fact there will be outside the friction, on this aspect In fact, it will be directly caused by the metal powder compression molding on the density of the uneven density distribution.
