Tablet Compression / Press

Tablet Compression / Press is most complicated machine of all the tableting machines and deep knowledge is necessary to make good tablets . The science of bringing Granules and fines together and compact or / compress to form tablet is termed as tablet compression.

In this article we will overview the important requirements to be viewed in tablet press before and after run and in subsequent articles we will discuss the Basics , Advanced and Deep advanced levels of tablet compression .

Installation of Tablet Compression / Press

Before run checkpoints

  1. Slide gates
  2. Pressure rollers
  3. Hopper level sensors
  4. Upper punch guide lock
  5. Lower punch entry seal
  6. Upper punch seals
  7. Lower punch seals
  8. Overload pressure / hydraulic pressure
  9. Lower punch retention system.
  10. Die lock torques
  11. Uniform die with turret
  12. Lubrication system
  13. Vacuum pickup
  14. Air purge working / slow and fast gates
  15. Dust cups / oil seals / bellows setting
  16. High Spot / Feed Frame installation
  17. Keying angle
  18. Fill cam selection
  19. Tail over die assembly
  20. Cam tracks
  21. Ejection cam
  22. Punch guides

After installation checkpoints

  1. Upper punch tightness
  2. Lower punch tightness
  3. RSD (Residual standard deviation) of force
  4. computer settings
  5. weight and thickness

Regular checks according to SOP of sensors.

  1. Rotary Encoders
  2. Strain Gauge
  3. LVDT sensors (Linear Variable Differential transducers)
  4. proximity Sensor.
