Pin Hole Detector for Tablet Blister Foil
Pin Hole Detector for Tablet Blister Foil - Raupack UK and Ireland

Speed 300+ detections per minute
Format rangeAny width required
Infrared backlight inspection system designed for detection of micro-tears in thermoformed aluminium - foil laminate or aluminium foil before filling. Our pin hole detection machine detects tears down to 10 microns. The shaped aluminium laminate is illuminated by infrared light before filling. A slit running across the foil transport direction must be milled in the foil guide rail to permit infrared light to pass from transmitter to receiver. Highly sensitive sensors detect the infrared light passing through any pin holes in the foil. Our Pin hole detectors are FDA-21 CFR Part 11 compliant.

    The Standard pinhole detector contains:

  • Transmitter and reciever in aluminium housing with display panel
  • Connecting cable with 16-pin plug
  • 100μ precision pin hole mask with certificate
  • Users manual including installation instructions and writing diagram
