​What is the difference between the TDP 1.5, TDP 5 and the TDP 6s?


This is a question that we get asked allot when it comes to the TDP range. In the TDP range there is the TDP 1.5, TDP 5 and TDP 6s. They are all really similar but the main distinction between them in the amount of pressure that they are able to exert when they make the tablet.

The TDP 1.5 is able to produce 15kn of pressure or 1.5 tons (1500kg or 3300Lb) when it produces its tablet. The TDP 5 is able to produce 5kn of pressure or 5 tons (5000kg or 11000Lb) when it produces its tablet. And the TDP 6s is able to produce 6kn of pressure or 6 tons (6000kg or 13200Lb) when it produces its tablet.

What that means in real terms is this. The TDP 1.5 Tablet Press can only really produce a good tablet up to 9mm (0.354in) maybe 10mm (0.393in) if the mix is really good. The tablets that are produced at this size are often soft or crumbly and not to a professional standard. If you need to make 6-7mm (0.236-0.275in) tablets then the TDP 1.5 can be a really good press for doing it.

The TDP 5 Tablet Press has allot more force and can produce a good tablet up to 12-15mm (0.472- 0.590in). The tablets that are produced on a TDP 5 are of a much better standard than the TDP 1.5. They are much harder and as long as the mix is correct they will have a sleek and shiny look to them. The TDP 5 will nine times out of ten cover the requirements of most people. You might need to produce more tablets in which case you will need a rotary press but as far as pressure goes the TDP 5 is good for almost all sports supplements, vitamins and minerals, homeopathic medicines and herbs and extracts.

For the TDP 6s in the same way as the other two TDP's the “6” stands for 6kn or 6 tons of pressure. This amount of pressure is only really needed when dealing with particularly difficult products. The TDP 6 does however have another advantage that the TDP 1.5 and 5 do not have. Because of the way that the pressure is adjusted on on the TDP 6s. On this model of TDP Tablet Press the pressure is adjusted vertically. This allows the TDP 6s pill press to very easily hold shaped tooling.

While the TDP 1.5 and 5 are able to hold shaped dies they do much better with round dies as the pressure is adjusted in a curricula motion by rotating the upper drift pin assembly.

The TDP 1.5 and the TDP 6s Tablet press also have the advantage of protective guarding. This casing sits around the drive belt on both of tablet presses and also covers the fly wheel on the 6s model.

Another dramatic difference between the 3 different single station pill presses is the weight. The 1.5 is 45kg (100lb), the 5 is 125kg (275lb) and the TDP 6s is 150kg (330lb). We would always recommend that when you get your tablet press that you use the mounting holes in the base to securer it down. If however you only have a small operating space and will need to move it around then the TDP 1.5 really is the only desktop press that can “easily” be moved. Even with the 1.5 we would recommend that at least two people move the press. When it comes to the TDP 5 and 6 we would say that in an ideal situation you would use a forklift to move and mount your press. In the event that this is not possible then 3 strong people are able to lift it short distances.

One of the biggest contributors to the weight differences on the 3 tablet presses is the motors. The 1.5 has a 0.55kw 4 pole motor while the TDP 5 and 6s have a 0.75kw 4 pole motor. This extra capacity gives the second two machines more power but also adds extra weight. All of the motors on TDP Tablet Presses are available in 240 or 110 volts for EU or US power supplies.

Another difference is the amount of tablets that each of the units is able to produce per hour. The

TDP 1.5 and 5 have a speed of 5400 tablets per hour. The TDP 6 Tablet Press achieves its extra pressure through gearing this reduces the production speed to 2500 tablets per hour.

So what press is right for you?

Honestly, unless you really need to move the press allot and only need to make very small round tablets then the TDP 1.5 is not for you. For the difference in price the TDP 5 is much better value in the long run. If you need to make tablets that are larger than 8mm it has to be a TDP 5 or 6s. I would not say that the money spent on upgrading to the 6s is not necessary unless you really do need to press some difficult products. The only other situation when I would recommend spending the money to get the TDP 6s is if you have to press irregular shaped tablets. That is why the TDP 5 is by far the most popular press sold by LFA.
