Reasons for thickness gauging and control:

There are a number of reasons for inline thickness measurement on extrusion lines for film and sheet,

some are listed here:

  • Less material consumption, due to possibility to produce with tighter tolerancesDickenmessung Extrusion
  • Reduction of wastage, due to quicker production start with an inline thickness measurement 
  • Proof of quality - prevention of claims
  • Tool for rejection of unwarranted claims
  • Enhanced productivity: quick production start, alarm if tolerance-limits are reached
  • Much better machinability of extruded film and sheet for printing or thermoforming e.g.

 melt-pumps - Kreyenborg Infrared Dryer - thickness gauges - automatic systems for extrusion-dies - electrostatic discharging
