A Complete Guide to Tablet Press Tooling System

An introduction to tablet press tooling system

Narrowly speaking, tablet pressing tooling system basically contains the punches and the dies of the tablet press. They decide the features of the tablets.

What is a tablet press tooling?

Like what’s introduced above, the punches and dies play a decisive role in tablet making. Not only are they essential components of tablet press machines, but they are also called tablet press tooling as well.

The punches can be divided into upper punches and lower punches. Together they compress the powder into tablets. In single punch tablet presses, only upper punches give force to the powder. In rotary tablet machines, both upper and lower punches work as sets in finishing the compression step.

The punches in rotary tablet machines are fixed to a turret. When the turret spins, it carries the punch sets moving through several cams. The lower punches mainly help hold the powder inside the die cavities. They also eject the fully compressed tablets from the die cavities after the compression stage.

The upper punches compress the powder to squeeze out the air inside first. Later, they compress the powder into pills precisely.

The die cavities and punches sets decide the shape and size of the tablets. Since these features are vital in tablet manufacture, the punches focus a lot on accuracy. Also, they must be durable in long terms of usage.

Types of tablet punches & dies

There are multiple types of tablet punches and dies in tablet press toolings.

The simplest type of tablet press tooling can make tablets in regular shapes——round, oval, etc.

If needed, they can also provide some tablets with symbols attached. Figures, letters are the most common ones, together with the division line.

Conclusion

The tablet press tooling system is the most essential part in a tablet compression machine. Choosing a proper tooling is of great importance in manufacturing tablets.
