    MACHINE MONITORING AND ALARMS

    The NP-500 Series Tablet Press is equipped with many advanced safety features, including:

  • Emergency stop buttons.
  • A stack light on top of the press for easy condition verification.
  • Hopper low-level sensors, with user defined shutdown delay, monitor low granulation levels.
  • Fail-safe switches on all doors, which immediately shut down the press if a door opens during production.
  • Temperature monitoring of lower compartments, oil and electrical enclosure.

    Optional safety features include:
  • Lower cam tight punch monitoring.
  • Lower punch temperature monitoring.

    DURABLE MAINTENANCE

    The NP-500 also offers superior maintenance features such as:

  • A press lubrication system that ensures continuous lubrication to spindle bearings and rear drive.
  • An automatic central grease pump that provides proper lubrication to all grease points on the press.
  • A power hydraulic unit that ensures precise control of overload settings, improving punch protection.
  • Illuminated upper and lower compartments for more proficient tooling examinations and troubleshooting.
  • Inspection windows in the upper and lower compartments allow for in-operation tooling inspections.
  • Vacuum nozzles on the die table and vacuum manifolds on the lower punches ensure a cleaner running press.
  • Optional lower tight punch and ejection force monitoring.
  • The hopper and feeder can be removed without the use of tools for quick cleaning and maintenance.
  • An optional AC unit can help decrease high temperature stress on lower compartment components, including lower punches.
  • Automatic grease pump lubrication system.
  • Vacuum nozzles on die table and vacuum manifolds on lower punches.

    RELIABLE TECHNICAL SUPPORT

    Unsurpassed worldwide technical support is easy to use, and available through a remote access Ethernet switch.

    A remote alarm notification service automatically notifies service technicians of press alarms via e-mail to capable devices.

    OPERATOR INTERFACE

    The NP-500 is controlled through a user-friendly touch-screen, mounted on a stainless steel control panel. The interface allows product-specific parameters to be stored as recipes, capable of recall at anytime. For protection, programmed security locks out unauthorized modifications of product recipes, machine settings and stored data.

    AUTOMATIC OPERATOR INTERFACE

  • Full machine documentation.
  • Maintenance and alarm screens, which provide easy troubleshooting.
  • Worldwide technical support.
  • 21 CFR Part 11 Compliant.
  • Touch screen computer mounted on stainless steel control panel
  • Recipe capabilities.
  • Maintenance screens.

    VFD PRODUCTION

    The NP-500 provides sophisticated production capabilities, such as a 15hp variable frequency drive (VFD), which controls turret speed while maintaining constant torque. This allows the press to deliver the highest quality tablets. To produce consistently accurate tablets, feeder speed and weight control automatically adjust, keeping the tablets within parameters defined by the user. In addition, automatic forced feeders provide more accurate fill for difficult flowing powders. To prevent overproduction, and reduce press runtime, a batch counter automatically shuts down the press at a user determined tablet quantity. An optional reject gate discards out-of-spec tablets. Engineering units are user selectable between Metric and English.

    INCREASE TABLET SIZE AND WEIGHT

    Providing precise control, the filling depth and tablet thickness are servo-motor controlled. The deep fill design increases both tablet size and weight, ideal for high compression ratio products. The increased die height design provides 100% more fill than the standard “B” die and 69% more fill than the standard "D" die.

    EXTEND COMPRESSION DWELL TIME

    The increased head flat diameter extends compression dwell time dramatically, reducing the need for pre-compression. The head flat diameter is 160% larger than standard “B” tooling and 56% larger than standard "D" tooling.

    IMPROVED HOPPER DESIGN

    The NP-500 features an enhanced oversized hopper design with butterfly valves, improving granulation flow control. This new design effectively seals the compression zone for a cleaner operation.

    Low-level sensor comes standard.
