Design of punch and die
The design of the pressing die should not only coordinate and select properly, such as the upper and lower punch body and punch hole, the outer diameter of the middle die and the middle die hole, the lower punch and the filling protection guide rail, the punch and the inner hole of the middle die, but also make the formed tablet output safely. In addition, special attention should be paid to the shape design of the die. For tablet manufacturers, the focus is mostly on the convenience of chewing or swallowing, the improvement of the therapeutic effect, and the appearance of tablets. As a die manufacturer, it is an important part of our work to design die to meet the needs of customers.
To ensure the service life of the stamping die, the design of the stamping die usually follows the three design principles of beautiful sheet shape, smooth sheet discharge, and high bearing capacity. Successful design is to meticulously put these three principles through the whole design process, and specifically implement them to the fine requirements of local or structural parts, such as the thickness of the edge of the special-shaped sheet die, the transition arc, arc, chamfer, and blunting of irregular structure, the high-speed tablet press, and different manufacturing processes for different structural parts, etc. In this way, die manufacturing costs will increase slightly, but the quality is guaranteed. It can be said responsibly that die design will directly determine the production cost of the user.
