Punches and dies are core components used in tablet compression tooling systems. Together, they determine the final shape, size, and surface details of a tablet. The upper and lower punches compress powder within the die cavity to form a solid tablet under pressure. The die defines the outer diameter and profile of the tablet, while the punches influence thickness, embossing, and break-line features.
Tooling is typically classified by standard types such as D, B, BB, and DB, and is selected based on the tablet press and tablet design. Punches are available in both single-tip and multi-tip formats, depending on production requirements. Keyway orientation in the punch head is essential for consistent alignment with the die cavity, especially in shaped or embossed tablets.
Die and punch compatibility is important for minimizing mechanical wear, ensuring smooth compression, and maintaining tablet uniformity. Tooling is designed with specific tolerances, clearances, and surface finishes to support continuous operation. Proper setup, handling, and maintenance are essential to achieve reliable performance over time. This tooling section covers both standard and custom configurations used across a range of tablet profiles and applications.
