Pharmaceutical plungers inspection systems

The plunger inspection system is the world’s fastest inspection system for pharmaceutical plungers. This system is a result of 15 years development in high-speed plunger vision inspection for quality control within cleanroom conditions.

The specifications are:

  • 13 plungers/sec
  • Possible with different plunger types
  • Wide color range
  • Top bottom, outside and inside surface inspection
  • Stamping and shape faults
  • 100% quality control with a minimum defect detection of 100µm
  • The rejected parts are categorized in separate containers and statistically traced.
  • Good parts are exactly counted and automatically packed
