The die pressure of the tablet press
The pressure of the die is directly related to the material, of course, the use of hard, wear-resistant materials can significantly increase the pressure of the die can withstand, the pharmaceutical industry (global) is more common S-7, of course, the cost is relatively high, in addition to expensive raw materials, processing costs are also high; The price of several other domestic materials is low, and the domestic suppliers are more commercial, which is the reason why the domestic punching die can be sold at a lower price.
The pressure that the die can bear is proportional to the area of the punch cross section, which is easier to understand;
The great pressure that the die can bear is not based on experience, but needs to be measured and calculated. This result is usually included in the factory test certificate or instruction manual by the supplier; Also want to explain, is able to withstand the pressure and you don't die tablet press show that the average pressure of delimit equal-sign, these two values apart from most of the domestic first tablet press of stress test results for the representation of the actual value, and the measuring principle is different, the two is a bit confusing, want to know can go to self-study, a simple example: big tolerance is within a certain time in certain pressure and die deformation when pressure value, and you in the process of the tablet, clear each die under "pressure" of the relatively short time, so there are a lot of people may find that even though you tablet press in more than suggest large pressure, No damage was found on the die, but this is still not recommended. The instrument to determine whether the actual value of the pressure is consistent with the displayed value of the equipment can use the German HBM. In addition, about whether the tablet press can withstand the pressure, in fact, the pressure that the tablet press itself can withstand is very large, the key is whether the punch can withstand, the punch may be different because of the material or specifications (such as 7mm and 10mm, can withstand the pressure is not the same), can withstand the pressure is not the same.
