Medicines are assuring and increase the health of people. The pharmaceutical field is expanding and so is the equipment technology. The machines are getting more and more advanced and the tablets are getting safer in their packaging and wrapping.

Those days have gone when the tablets were needed to be placed and arranged on the conveyor belts and they were compressed and packed by foils with high wastage costs. Also, the involvement of human hands had more probability of getting bacteria on to them. They are known and preferred by the experts of this field because they have all the features required by the manufacturers of tablets.

These are the machines used to compress powder into tablets of standardized size and weight. They are used for manufacturing tablets of a broad spectrum of materials, including pharmaceuticals, drugs i.e. MDMA, cosmetics and cleaning products.


The fundamental operation for them may be divided into three distinctive stages: flow, compression and ejection. Flow is the tendency of the granulation to flow like a granulated material. Compression is the creation of tablets within the dye. Ejection refers to the collection the tablet out of the dye.

It applies a combined pressing action by two punches and a dye to form the tablet. In the first step of the simplified operation, the bottom punch is lowered in the dye, which creates a cavity to be fed by the granulated feedstock. The accurate depth of the lower punch can be precisely controlled to measure the amount of powder that fills that cavity. The excess is worn out from the top of the dye, and the lower punch is forced down and temporarily covered for preventing spillage. Now, the upper punch is forced down to bring it into contact with the powder and the cover is removed. High pressure compression rolls deliver the force of compression to fuse the granulated material together into the tablet. Then the lower punch is raised to drive out the tablet.


Tablet press machines may be categorized into two types.

  1. Single-punch press machines.
  2. Rotary tablet press machines.

Most high speed tablet press machines take the form of rotating turret that may hold any number of punches. When they rotate around the turret, the punches come into contact with the cams to control its vertical position. Punches and dyes are usually custom made for each application, and may be designed in a wide variety of shapes and sizes; and may also be customized for scoring lines to make tablets easier to break with manufacturer codes encrypted.

Important Consideration While Choosing

There are some things that should be considered when buying tablet press machines. One of those things which should not be overlooked are the devices which offer closed systems, especially if they are making medical-tablets, because they will prevent cross-contamination with other products. Another thing is the machine’s capacity to change the compression and charging modules. The capacity of the machinery should also be checked; how many tablets can the machine produce, within a certain amount of time.

Final Verdict

High performance rotary presses are known to be productive, reliable in operation, robust and precise as well. Another advantage is the amount of security, automatic process monitoring and application of high-quality standard components.
