A mechanical device known as a tablet compression machine, also known as a tablet press machine, tablet making machine, tablet machine, or tablet punching machine, is used to compress API and excipient granules or mixtures into tablets of a uniform and predetermined size, shape, and weight for research, pilot-scale manufacturing, and full production.
Tablets are oral dosages that have healthy-improving active ingredients. Pharmaceutical companies need dependable machines with precise engineering to maintain the quality of the product because they produce hundreds of tablets per day.
Tablet compression machines have helped manufacturers produce tablets more quickly and effectively as the industry has developed over time.

A TABLET COMPRESSION MACHINE: WHAT IS IT?
Granulated powder is transformed into pressed tablets of a consistent size and weight using a tablet compressing machine.
The pharmaceutical industry makes extensive use of tablet press machines to compress a variety of powdered materials into tablets using the compression principle. Punches and dye are used by manufacturers to turn powdered materials into pills.
Tablet compression machines are practical devices that are used to make tablets. As the powder is compressed inside the tablet, this tablet press is at work.
The machine’s advantageous feature is that it creates tablets of uniform size and shape. The rotary press is used in a variety of sectors, including the salt, pharmaceutical, nutraceutical, chemical, and food industries. The equipment’s punches are used to apply high pressure to the granules and powder in order to press them down and mix the materials.
This is how the machine’s mechanism operates. In general, there are two types of tablet compressions: single rotary tablet presses and double punch rotary presses. The mini-tablet press uses a single tooling mechanism, whereas the double-sided rotary tablet press uses a variety of tooling mechanisms to carry out the process, which is the main distinction between the single tablet and double tablet presses.
Salt industries use tablet compression machines to create salt tablets. This salt tablet is used to treat pool water, and salt tablets are used to purify the water.
BENEFITS OF A TABLET PRESS MACHINE

- The pill press machine can now handle a variety of materials and is simple to maintain and use thanks to technological advancements.
- Machines for pressing pills, like multiple station tablet presses, are affordable and can be adjusted to your production needs.
Manufacturers of tablet compression machines go by the following names: GEA Cadmach Natoli Bosch Fette Korsch Kilian.
The rotary tablet press machine’s primary functional components are:
Hopper
The granules/powder mixture (API and excipient) is stored in the hopper and supplied to the feeder system.
It serves as the entry point for granules or powder mixtures into the tablet press, where tablets are compressed. Granules or powder mixtures can be fed manually or automatically.
Feed Peddles
In a high-speed machine, these continuously rotating paddles ensure accurate and consistent granule feeding into the die cavity.
Granules for the tablet will be fed into the die system through the feeder housing from the hopper.
Feed Frame
A feed frame rather than a feeder system is used in some tablet press machines (Feeder Housing and Feed Peddles).
Under the influence of gravity, the feed frame feeds the granules/powder mixture into the die cavity. The feeder system or feed frame must be attached to the tablet scraper and excess granules stripper.
Extra granules remover
This section of the tablet press machine removes extra granules from the die bore or cavity’s surface. The volume of the granules, and ultimately the weight of the tablets, are under the control of the granules stripper.
Stripper for granules tablet press Die
The tablet’s size and shape are determined by the die. In a die bore or die cavity, powder mixture or granules are compressed into tablets of the desired length, width, and shape.
Punching dies for tablet presses
Granules and powder are combined in the die bore and compressed by two punches (upper and lower).
The tablet is compressed inside the die cavity as the lower punch moves upward and the upper punch moves downward. The lower punch then moves upward, followed by the upper punch.
Turret
The turret secures the location of the die bore, two punches (lower and upper), and the die on its holes during the tablet compression process. The heart-shaped portion of the tablet press machine is called the turret.
Cam tracking
The upper and lower punches in the tablet compression process are guided by a cam track, which is crucial to a smooth tableting process. The cam track assists in moving the punches up and down as the turret rotates.
Compression Rollers
The tablet press machine uses rollers to compress the granules into tablets of the desired hardness by applying a predetermined and sufficient amount of force. There are typically two sets of compression rollers on tablet press machines.
Also, the initial compression force is provided by pre-compression rollers. Pre-compression aims to remove any air that might be present in the die or granules/powder mix.
The primary compression roller applies enough compression force to the granules to turn them into tablets. To guarantee uniform tablet thickness and size throughout the compression process, the rollers remain stable and vibration-free.
Tablet/Takeoff Blade Scraper
To scrape the compressed tablet into the discharge chute, this is mounted in front of the feed frame or feeder system.
The compressed tablets are pushed away from the die table of the compressing machine and into the discharge chute by a device called a tablet scraper, also known as a takeoff scraper or tablet takeoff.
Weight-Controlling Tablet
With the aid of various cam system movements, material will flow into the die cavity based on the position of the punches. This is used to adjust the volume of the granules to be compressed and thereby determines the weight of the tablet.
Types of tablet compression machines in the pharmaceutical sector
- A COMPRESSION MACHINE FOR SINGLE PUNCH TABLETS
Companies use single punch tablet compression to make a wide range of medications into rounded tablets.
These machines produce a relatively smaller batch than multiple press machines. They assist in the production of chewable tablets, effervescent tablets, and other powdered tablets in the pharmaceutical industry. The features of single punch tablet compression include the ones listed below:
- The machine’s enclosed design prevents dirt and dust from getting inside.
- is more space-efficient and reasonably compact.
- The machine gives you a high utilization ratio with the right setting adjustments.
- trial-and-error is necessary when setting up the production process.
- Double-sided rotary tablet press with a compression mechanism
- ROTOR COMPRESSOR FOR TABLETS
A mechanical device called a rotary tablet press uses multiple tooling stations to compress powder mixtures into tablets of a consistent size, shape, and weight.
This machine is used by a number of industries, including the pharmaceutical, nutraceutical, and cosmetic industries, to increase production.
The equipment is specifically used for high-volume manufacturing. The rotary tablet press machine has the following features:
- Reduces the amount of powder formulation waste.
- The setup is much more effective than a single press machine, and the machine gives you control over the manufacturing process.
- Typically automatic, rotary tablet presses can produce 150 tablets per minute of tablets.
- Depending on the machine’s model, it includes a hopper, feeder, slider, and other adjustment features.
The Double Tablet Compression Machine’s Common Applications
Double tablet compression machines are used in a variety of industries for a variety of purposes, including the manufacturing of particular tablets and other cosmetic products that call for distinct pharmaceutical and manufacturing industries.
The fact that this machine has a mechanism for interacting with a multi-tooling system makes it applicable. The double-sided rotary tablet press is used to create tablets at a rapid rate because the machine’s mechanism carries out the process with extreme precision.
This machine also processes the items (tablets) by filling the tablet with powder and granules after being punched.
In tablet compressors, double lifter camps, which are typically present in electrical tablet presses, are used to lift the tablets using an electrically powered counter machine.
In actuality, the machine has three different types of guards: a lower guard, an upper guard, and a turret guard.
Since the machine has an interlock system that enables automatic shut-down when it is not in use, this mechanism is regarded as an appropriate use for the machine.
