A tablet press is a mechanical device specially designed to compress dry granular or powdered materials into tablets by pressure.
It is widely used in many industries such as pharmaceuticals, food, chemicals, and cosmetics, and is mainly used to produce tablets, sugar tablets, calcium tablets, chewing gum tablets, seasoning tablets, catalyst tablets and other products.
The basic working principle of tablet press is to compress the material in the mold through one or several pairs of punches (upper and lower punches), and then form tablets of the same size and shape.
The material is first fed into the mold through the feeder, and then the upper and lower punches move vertically relative to each other, thereby applying pressure to the material for extrusion. The shape and size of the compressed material are based on different customization of the mold. After compression, the tablet is ejected from the mold to form a discharge. The subsequent process generally needs to be connected to a tablet screen for dust removal and polishing, and a metal detector to reject tablets that exceed the standard, which is convenient for subsequent tablet packaging, such as connecting a tablet counting machine for tablet counting and bottling, and connecting to a blister packaging machine for blister packaging.
Single punch tablet press: Usually used in laboratories or small batch production, it uses a cam or eccentric wheel connecting rod mechanism to make the upper and lower punches produce relative movement to press tablets.
Multi-punch rotary tablet press: This type of tablet press drives multiple molds to perform vertical reciprocating motion through a rotating turntable to achieve a continuous tableting process, which is suitable for medium to large batch production.
High-speed tablet press: High-speed rotary tablet press: Similar to the rotary tablet press, but the turntable has a higher rotation speed, which can achieve very high production efficiency and is suitable for large-scale industrial production.
Special-purpose tablet press: Such as double-layer tablet press, special-shaped tablet press, etc., are used to produce tablets with special shapes or structures.
Tablet presses manufacture a wide variety of products in different industries. Here are some specific examples:
This is the most widely used field for tablet presses, mainly for the manufacture of pharmaceutical tablets, including ordinary tablets, controlled-release tablets, effervescent tablets, etc.
Typical products
Ordinary tablets: This is the most common form of tablets, covering a wide range of categories from antipyretic analgesics (such as aspirin, ibuprofen), antibiotics (such as amoxicillin), cardiovascular drugs (such as antihypertensive drugs) to psychiatric drugs (such as antidepressants).
Controlled-release tablets: This type of tablet is designed for slow release of drugs to extend the effective time of drugs in the body and reduce the number of medications, such as drugs for chronic disease management, such as diabetes treatment drugs.
Effervescent tablets: Containing sodium bicarbonate and organic acids, they react to produce carbon dioxide when in contact with water. They are often used in cold medicines, digestive medicines, etc. to increase the solubility and absorption rate of drugs.
With the rise and popularization of the concept of health, the demand for tablet presses in the health care products industry is also growing.

Solid beverages and condiments: such as instant coffee tablets, tea tablets, etc.
Cooking condiment tablets: such as chicken essence blocks, seasoning blocks.
Special foods: such as compressed biscuits, energy bars, etc., which are usually used as portable food in outdoor adventures or military operations.
Tablet presses with high corrosion resistance, high temperature resistance, explosion-proof and safety performance have been applied in the chemical industry.
Typical products
Catalyst tablets: Catalyst tablets used in chemical processes such as petroleum refining, synthetic ammonia, synthetic rubber, etc., such as nickel catalyst tablets, molybdenum catalyst tablets, etc.
Fertilizer tablets: used in agricultural production, such as nitrogen fertilizer tablets, phosphate fertilizer tablets, potassium fertilizer tablets, etc., which are convenient for farmers to apply on demand.
The above is the current major classification of tablet press applications. With the continuous advancement of technology, its application scope and the types of products manufactured will become more.
In the above content, a brief introduction has been made to the types of tablet presses. How to choose a more suitable tablet press to match the actual needs in order to achieve the purpose of improving production efficiency, ensuring product quality, and reducing costs, etc., needs to be selected based on the following key factors.
1. Production demand
Output and scale
First, clarifying the expected production volume is the first step in selection. It is a suitable choice for laboratories and small-scale production to purchase manual or single-punch tablet presses. Large-scale continuous production that needs to improve production efficiency requires high-speed, fully automatic, multi-punch rotary tablet presses.
Types of tablet products
Different industries have different requirements for tablets. For example, the pharmaceutical industry focuses on the consistency, hardness and sustained release time of tablets; the food industry may pay more attention to the taste and appearance of tablets. Therefore, the applicability of the tablet press needs to match the product characteristics.
Pressure range
The pressure of the tablet press is a very important parameter, which determines the type of processable materials and the hardness of the tablets. Understanding the optimal compression pressure of the material and choosing the right machine model are the prerequisites for ensuring tablet quality.
Custom molds
Custom molds are the key to achieving tablet size and shape, and the core parameters are the diameter and thickness of the tablet. Although the tablet press is a multi-purpose machine, different tablets can be produced by replacing different molds on a machine, but the size and number of molds that the turntable can accommodate are very important foundations.
Automation level
For medium and large enterprises, medium and large batch production, and pharmaceutical factory production, it is recommended to choose a highly intelligent and automated tablet press, so as to reduce manual intervention, reduce production costs, and improve production accuracy and consistency.
Maintenance and cleaning
In the pharmaceutical and food industries, tablet presses that can ensure the hygienic standards of the production process are more popular. Meeting high standards of hygienic requirements requires that the machine is easy to maintain and clean.
High-end tablet presses have realized PLC one-button operation to lift the turntable and automatically move it to the outside of the machine, so that the operator can easily remove the mold for cleaning and maintenance, which fully reduces downtime and reduces maintenance costs.
Durability
The turntable and mold of the tablet press are parts that are constantly subjected to collision and friction during long-term operation. To reduce long-term operating costs, the service life of these two parts is a very important point. The tablet press turntable we manufacture is forged with QT600 ductile iron. After 12 months of internal stress release, it is stable as new even after more than ten years of use. The mold is made of GCR15 material, which is wear-resistant, pressure-resistant and corrosion-resistant, and can easily achieve larger diameters and tablet thicknesses.
Industry standards and certifications
When you purchase a tablet press, you need to ensure that the selected tablet press meets relevant industry standards, such as GMP (Good Manufacturing Practice). If you are using it in the European market, the machine must meet CE, RoHS, EMC, LVD, etc. The requirements in the North American market are the highest. In addition to the standards mentioned above, you not only need to obtain FDA certification, but also need to find a tablet press that meets UL and CSA certification.
Hardware safety
The tablet press should be equipped with complete safety devices, such as multiple emergency stop buttons to ensure the safety of operators, isolation shields to isolate materials from cross-contamination with the external environment, etc.
Supplier reputation
