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

Temperature Measurement of Thermoformed Plastic using Landscan
 
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 color or gloss.
 
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

  Top of pageThe Landscan processor and thermoforming software, used with Landscan Pro (LSP) infrared linescanners, provides high precision measurement on the individual zone temperature distribution on plastics sheet produced by rotary thermoforming machines.

The 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.
