Needle Assembling


Stevanato Group has designed two different models of needle assembly machines, both geared towards ensuring ease of use, low footprint, and energy saving.

The machines are designed to insert the needles into the glass barrels and glue them to the latter.

A camera inspection system checks the process from both a cosmetic and dimensional point of view.



The ASA36 is a flexible off-line machine ideal for assembling a wide range of needles and syringes.

The machine comes with an automatic de-blistering system for the syringe infeed and an automatic blistering machine for the syringe outfeed.

The system is equipped with a complete range of inspection systems for the adhesive, needle and glass syringe.


  • Processes up to 52 pieces per minute
  • UV lamps for curing of the glue
  • Dimensional and cosmetic inspection system performed
    by a dual-camera system with static syringe:
    • Needle oscillation
    • Needle tip integrity
    • Total length of the syringes with needle
    • Glue inspection
  • Flow test: to measure the air flow through the needle


  • Easy set-up
  • Automatic blistering and de-blistering machine
  • High-precision pick-up device
  • Needle loading system with servo motor
  • High number of stations for a broad range of syringes/needles
  • High processing speed and repeatability
  • Flexibility to suit a wide range of needles and syringes
  • Integrated with fully automatic control system




NAM is a needle assembly machine that can operate both in-line and off-line.

Besides reaching higher speeds (up to 120 pieces/min), NAM combines improved process quality and a more efficient cosmetic and dimensional inspection.

These results are achieved thanks to:

  • No glass-to-glass contact

  • No glass-to-metal contact

  • LED-light curing system (reduced energy consumption and improved glue polymerization)

  • 1 dedicated carousel for each of the following 3 operations:
    • Needle insertion
    • Glue curing
    • Dimensional and cosmetic inspection

  • Dimensional and cosmetic inspection based on a high-precision camera system with the rotating syringe:
    • Needle oscillation
    • Needle tip integrity
    • Total length of the syringes with needle
    • Glue inspection

NAM is designed for use in ISO 8 clean rooms.


NAM ensures excellent accessibility for:

  • Testing
  • Maintenance
  • Cleaning
  • Batch change
  • Format change-over
  • Dynamic buffer at infeed
  • Energy-saving LED curing stations
  • Needle magazine loading while the machine is running
  • 360° inspection of containers
  • Reduced footprint
Glass Processing - Needle Assembling - NAM3


  • LED curing, energy saving, low maintenance and cost-convenient spare parts
  • All movements are servo-controlled
  • Reduced number of mechanical parts
  • Limited number of format parts
  • Inlet and outlet sampling station
  • Needle magazine loading while the machine is running
