Tablet Tooling in TSM and EU Standard

The punches and dies is called tablet tooling that determines the shape, size and the identification markings of the tablets. The tooling must meet the specific requirements to satisfy the needs of dosage uniformity, production efficiency and esthetic appearance.

Internationally there are two recognized standards for tablet compression tooling: the TSM standard and the EU standard. TSM is acronym for the “TABLET SPECIFICATION MANUAL”, widely recognized and exclusive in the United States. EU, more widely used than the TSM, is short for “EUROSTANDARD”, considered as the European standard and also globally applicable.

Based on the standard of TSM and EU, tablet tooling is mainly classified as B tooling and D tooling. The B tooling punches and dies can be further classified as BB, and D tooling can also be used on B tooling machine that is call as DB. These sub categories of DB, BB type tablet tooling are made depending on the punches and dies requirements of product.

 What is the difference between B&BB tooling and D&B tooling?

B Tooling: the same as BB tooling, only difference is the lower punch length is just 3 and 9/16th inch.

D Tooling: its punches and dies usually have thicker diameter or greater diameter of their body as well as the tip of punches with greater outer diameter compared to B tooling.

D tooling 25.4 38.1 133.60 25/25
BB tooling 19 24 133.60 13/14
DB tooling 25.4 30.16 133.60 19/19

 

The type of pill press tooling (B, D,) is mostly selected to improve the productivity during commercial manufacturing. The productivity will be 20 to 25% more in B tooling compared to D, assuming the same speed and diameter of turret of machine as number of stations.

Hardness which can be achieved might be more in case of tooling due to larger dual time. It can lead slower dissolution if dissolution is hardness dependent.
