Infrared Temperature Measurement | Combustion & Environmental Monitoring

Plastics

The Landscan Thermoforming System allows thermoformers to monitor and record the temperature distribution of plastics and improve operating efficiency and product quality.

 

Constant, accurate temperature information is critical in the thermoforming process to ensure that the finished product is correctly formed. Low forming temperatures produces stresses in the formed part and temperatures that are too high can cause problems such as blistering and loss of colour or gloss.

 

Features
  • Simple installation with customised configurations
  • Extensive storage, display and analysis capabilities
  • Process temperature data from multiple sensor heads, and database and archive files simultaneously
  • Display thermal images and temperature profiles
  • Display include: thermal map, profile, 3-D, two independent zone models, centre-line deviation, subtracted thermal map and envelope profile
  • Spot temperatures analyzed at any point
  • Detailed user-defined zone temperature analysis

Benefits

  • Rapid adjustment of heaters for proper heating of sheet
  • Improved product quality and operating profitability
  • Detect product defects and failing heating elements quickly
  • Automated quality monitoring
  • Reduced set-up time and scrap rate
  • Split, merge or override individual heater segments

The Landscan LSP_HD infrared linescanners, provides high precision measurement on the individual zone temperature distribution on plastics sheet produced by rotary thermoforming machines.

The WCA (Landscan) software calculates and corrects for the distortion of thermal profiles caused by movement of the heated sheet on rotary machines during the thermoforming process, allowing accurate determination of zone heating temperatures.

Distortion occurs in a conventional image when the heating sheet indexes out of the oven, and traverses through the linescanner field-of-view.

Accurate measurement of the sheet temperature, as it exists the thermoforming oven, provides temperature data for the oven heating control system in order to achieve the required thermal profile in each zone.
