TABLETING
The ISO 18084 covers the standard B and D tool confi gurations
This is the furthest from the truth whereas the drawings are created for the tool manufacturer as a guide to manufacture and for tablet press manufacturers looking for help with cam confi guration, turret guide and die pocket dimensions. The tool drawings published by these standards should be used for an incoming quality inspection process to ensure the tools were manufactured to the prescribed standard and will perform as intended. Once the new tools pass acceptance
A single tip punch
Standardisation and is referred to as the ISO 18084. ISO 18084 covers the standard ‘B’ and ‘D’ tool confi gurations, but it is not as complete or comprehensive as the TSM. The original standard was the
IPT (now known as the TSM) fi rst developed by multinational pharmaceutical companies in the 1960s. The purpose was to establish tool drawings that could be shared with local machine shops to ensure
that the tooling would properly fi t and perform in the most common tablet presses, assuring consistency with tablet quality attributes such as tablet hardness, weight and thickness.
THE IMPORTANCE OF DRAWINGS The engineered tooling drawings available with both standards can be misunderstood as wear limits to identify when the tools are unusable.
inspection, they should be updated to an in-process status. When the tools have been reclassifi ed then it is up to the tool user to establish a new set of tolerances that are an acceptable deviation related to the product or application. The tooling supplier will be able to help establish in-process tool deviations to assure the tool user that their tooling will continue to produce tablets that meet quality parameters. In most cases this will greatly reduce the annual tooling spend. Tablet manufacturing involves the
interplay of many factors. The role of the tooling supplier is crucial for the optimisation as well as troubleshooting the user’s tableting process.
