Visual Help for Estimating Tooling Damage

Making a good tablet is not only related to tabletting techniques, but also the quality of tooling set. Tabletting techniques largely relies on the operator’s handling, including the first response to unexpected emergencies, decisions on what to do next, etc. While the quality of tooling set needs to be checked regularly, replace it when wear out. But the problem is how to check? How to decide save it or discard it? What is the principle for judging? This writing aims to show how to estimate tooling damage wth visual help.
In general, there are five levels we separate them based on the damaged condition of the punch and die tooling. Estimation should be focused on the tooling cup edge, tip edge, and head pitting. The wholly new toolings, slight and moderate damaged toolings are still serviceable, but the severe-damaged and totally damaged ones should be discarded, or the tablets they produce are unqualified, a waste of time and labor effort. Hence, visual aid is requested to assist estimating the damage condition.

As is well known, quite a few punch tooling sets are set in the rotary tablet press. Take ZP-9 as an example, there are 9 sets of toolings. It is necessary to regularly examine every punch and die one by one according to above introduced guidance with the help of visual aid. Moreover, you just need to replace the worn ones rather than the whole 9 sets. By the way, custom-made tooling are available in our shop, irregular-shaped punch die, 3D molds, multi-tip tooling etc.
