NP-255

Setting a New Benchmark for Ease of Operation

The NP-255 is a robust tablet press that was built to meet even the most demanding needs of the mid-sized tableting industry. The press has features and options designed to increase production, improve tablet quality, reduce waste, and set a new benchmark for ease of operation. Designed, engineered, and manufactured in the USA, this unique machine has a maximum production speed of 192,000 tablets per hour.

With a hardened steel die table, a gravity feeder that is interchangeable with a two-paddle forced feeder, and our industry-leading intuitive Natoli AIM™ ProPlus control system, the NP-255 is the new standard for value in the mid-sized tableting industry.

  • Standard TSM and EU B, D, or BB tooling
  • Intuitive AIM™ control system provides operation feedback to help maintain tablet quality and improve productivity
  • Continuously lubricated punches, cams, and turret to help eliminate wear, reduce heat, and minimize product sticking issues
  • Tablet weight, thickness, and hardness adjustments can be made as needed during production
  • Completely segregated compression and mechanical zones
  • Punch barrels and die table are vacuumed during production to eliminate build up and reduce change over time
  • Upper and lower punch guides have soft seals to reduce punch binding and heat in the punches, and contain the product granulation
  • Reduced product loss with our specially designed feeder and powder recirculation system
  • Upper and lower cam track guards keep cams cleaner to reduce heat, wear, and increased tooling life
  • Lower punch retainers to help maintain consistent tablet weight
  • Direct drive gears for decreased wear and slippage
  • Turret mounted with upper and lower tapered bearing
  • cGMP- and CE-compliant

  • Instrumented force monitoring
  • Combination caster/levelers for easy mobility and setup
  • Dual-paddle power rotary forced feeder
  • Tablet reject chute
  • 3VT System
  • Hopper vibration unit
