Why There Is A Need To Standardize Tablet Punches And Dies

By Carl Lewis


Pharmaceutical companies are a large industry that manufacture so many things. They make mostly medicines, among many other things, and they can come in various forms. From tablets to capsules and syrups, these things require some sort of equipment to make. The machinery and apparatus used for this also have standards to follow for making sure that the quantities of substances are at a proper amount.

Tablet compression was once a manual method, but with the development of technology, manufacturers have found a way to automate the process. This makes assembly line production of tablets and the like easier. Tablet punches and dies are popular machines to assist in tooling.

It becomes a different story for the manufacturers. The standardization of these parts and equipment in machinery can save so much in overhead expenses. Tablets, specifically, come in different forms and sizes. Its dosage can differ without changing its physical form, but the question remains to be why they all look different. Standardization is meant to address these differences to solve manufacturing difficulties.

Back then there was a manual way to produce these things. They may even be used for candy and other things that are in tablet form. Machinery called tablet compression tools are needed to do press the tablets and reduce the powder into something that can be taken in with a particular dosage. Two famous standards are used for this namely the Euro ISO and Tablet Specification Manual or the TSM.

These are the European ISO, used in Europe and mostly outside the US and the Tablet Specification Manual standards used by mostly North American Manufacturing. This is a big deal for manufacturers that have plants around the world. Not having a set of the same metrics to follow mean extra expenses. Resources are expended to qualify the product and equipment for it to be allowable in that certain location.

Procurement, maintenance and operation would also be easier for contractor or OEM staff since extra knowledge needed for machine specifications is avoided. This also saves companies from replacement and other fixes since parts for the machine would be easily found. The EOMs who make these parts would also be able to deliver their product faster.

The differences are very small but these minor variations are what makes interchangeability impossible between machines. The punches and dies have to be compatible for them to work properly. This makes the whole tablet making process costly. Pharmaceutical companies would have to have a variety of machines just to follow the set qualifications depending on where they will be selling the product.

Back in the 1990s there was very little interest in the topic of standardization tablet compression machinery. The companies probably did not want to risk losing their own unique advantages against competition. But eventually the Euro ISO ended up being one of the most widely used one in the industry.

Technically speaking, there are very minor difference in the table punches and dies that are used in the machines. But it does not make sense how these small variations can affect cross compatibility of equipment which would help lower costs for production. Putting up the standard potentially lessens the overall costs of production which would lessen the cost for consumers.
