A Laboratory Tablet Press Machine (also known as a lab-scale or R&D tablet press) is a compact, precision-engineered device designed for compressing powdered or granular materials into uniform tablets. It is primarily used in pharmaceutical research and development (R&D), quality control labs, and small-batch production for testing formulations, feasibility studies, and product characterization. Unlike industrial rotary presses, lab models prioritize flexibility, ease of use, and minimal material consumption, allowing high-quality tablet samples to be produced from very small quantities of powder.

How It Works
-
Filling: Powder or granules are fed into a die cavity via a hopper or mechanical feeder.
-
Compression: Upper and lower punches apply controlled force to form the tablet.
-
Ejection: The finished tablet is pushed out and collected, with scrapers preventing adhesion.
-
Monitoring: Integrated software analyzes parameters like weight, thickness, and hardness in real-time.

Pre Compression & Cleaning
Pre-compression is available to expel air trapped within the material in the die and to pre-densify the material prior to passing through the main compression rolls. This feature improves the quality of the product.
Spacious compression zone with acrylic guards gives a convenient access for cleaning purpose. Lower punch scraper seals prevent material passing through the lower punch guides into cam tracks. Ejection of excess powder reduced by proper selection of adjustment cam. Suction needle provided for clear dust particles during compression Process.
