There are several different characteristics of Dry Powder Pressing Mold
First, the tough performance: the basic all of the Dry Powder Pressing Mold in the working conditions are relatively poor, there are many need to bear a greater impact on the load, resulting in its regular brittle fracture and the phenomenon. In order to better prevent the Dry Powder Pressing Mold parts in the process of work, suddenly brittle situation, and the precision Dry Powder Pressing Mold with a strong toughness. In fact, the most important toughness of Dry Powder Pressing Mold depends on the amount of carbon in the material, as well as the grain size and the main state of the organization.
Second, the high temperature performance: When the entire Dry Powder Pressing Mold in the work of the temperature is relatively high, it will lead to its strength and hardness decline, eventually leading to Dry Powder Pressing Mold appear earlier wear, or because of plastic Of the deformation caused by its failure. So the precision Dry Powder Pressing Mold is the need for its high resistance to tempering stability of the treatment, to ensure that Dry Powder Pressing Mold even in high temperature working environment, can still have a high strength and hardness.
Third, fatigue and fracture performance: Dry Powder Pressing Mold in the course of the work, because the long-term cycle and stress, often lead to its fatigue fracture, but in the form of small energy will appear multiple impact Fatigue fracture, or fatigue fatigue fracture, etc., so Dry Powder Pressing Mold on the cause of the fatigue fracture, mainly depends on its hardness, toughness and strength.
What do we need to pay special attention to when we work on the precision Dry Powder Pressing Mold? Sophisticated Dry Powder Pressing Mold is a high-grade, technically demanding, and requires special attention to the problems that may occur during your process in order to ensure the quality of the product. Here and Xiaobian together to understand the next bar!
First, in the semi-finishing before the need for the opposite side of the base for the correct precision;
Second, the Dry Powder Pressing Mold before finishing, to the entire process of the reference hole to find, but also on the inserts in the margin to check;
Third, after the completion of the entire Dry Powder Pressing Mold finishing, the accuracy of the corresponding checks.
Dry Powder Pressing Mold Design The main parts include: female mold, mandrel, die punch. Dry Powder Pressing Mold design first manufacturers to provide product plans, and then determine the way of forming, collecting the basic parameters of the compact design to calculate the size of the compact. Calculate the Dry Powder Pressing Mold size according to the size of the compact and the service conditions and requirements. Finally, with Dry Powder Pressing Mold, if the blank is qualified, this Dry Powder Pressing Mold compound requirements.
The abrasion resistance of the material is one of the most basic and most important properties of the Dry Powder Pressing Mold. The next words, we actually have to pay attention to the hardness itself in terms of words, that is, will affect the wear resistance of a major factor. In general, the higher the hardness of the Dry Powder Pressing Mold part, the less it will wear and the better the wear resistance.
On the other side, we actually have to pay attention to the wear resistance itself is in fact and the material which is the type of carbides, the number and its shape, size and its distribution has a relatively large relationship. Moreover, in terms of another aspect, when it comes to the selection of Dry Powder Pressing Mold, it is, on the other hand, it should have better strength and toughness.
Dry powder Pressing Mold in the long-term role in the process of cyclic stress, in fact, it is necessary to pay attention to the need to bear many shocks, it is precisely because of this, in terms of its own terms, we actually have to pay attention to it itself is facing The greater the impact load, this way, that is, will be more likely to lead to its broken behavior.
So in order to prevent the Dry Powder Pressing Mold parts in the work of the sudden fracture of the phenomenon, on the Dry Powder Pressing Mold itself, in fact, it should be a relatively high strength and toughness. However, in fact, we should pay attention to the toughness of the Dry Powder Pressing Mold, it will depend to a large extent on the material itself, a carbon content and its grain size and organization and its inclusions The content and strength.
There are some Dry Powder Pressing Mold, such as plastic mold in the work of the time, in fact, to a large extent, there is the existence of plastic chlorine, fluorine and other elements, in view of this, we actually will be noted that in its heat After that, that is, will break down the precipitation of HCI, HF and other strong corrosive gases, so that it to a certain extent, it will erode the Dry Powder Pressing Mold cavity surface, so that its surface roughness increased, Exacerbated wear failure.
