Tablet presses are used to compress powder and form tablets, pills, or vitamins.
They are defined as manual, semi-automatic or fully automatic machines that can be used for the compaction or molding of solid tablets. They are also sometimes referred to as tablet punching machines. The early tablet presses were single punch machines adapted from metal presses used for stamping steel and other materials and produced 400 to 600 tablets a minute, whereas the modern tablet presses of today can produce up to 10,000 tablets per minute.
Tablet presses are used by pharmaceutical, nutraceutical and cosmetic companies. They are required to be easy to clean and quick to reconfigure with different tooling, because they are usually used to manufacture many different products.
Tablet presses, also called tableting machines, range from small, inexpensive bench-top models that make one tablet at a time (single-station presses), to large, computerized, industrial models (multi-station rotary presses) that can make hundreds of thousands to millions of tablets an hour. They compress a volume of powder, captured in a die, between two rollers using an upper and lower punch. Once the distance between the rollers is set, the compression force will stay the same, thus ensuring that tablets are compressed to an equal thickness (ET). Many newer tablet presses include a CNC or computer control element. This greatly increases the efficiency of the production process by making it easier to coordinate different stages of production. Pressing rate, rotation speed, and automated tooling inspections are often features of computer controlled presses.
Tablet press are expensive pieces of equipment and they are a very valuable resource for those using them. Many consider quality used equipment for their cost efficiency and immediate delivery. We have been providing that option since 1997 and are proud members of the Machinery Dealers National Association.
