Working Principle Of Heat Seal Tester GT-N70A
The GT-N70A laboratory heat sealer adopts the heat pressure sealing method, the standard principle for professional heat seal performance evaluation. Below is the detailed working process:
Heat Pressure Sealing Mechanism
Place the sample to be sealed between the upper and lower heat sealing heads. Under the preset temperature, pressure and time, the sealing of the sample is completed. Through repeated tests, it provides guidance for users to find suitable heat sealing parameters.
Precision Pressure Control
To ensure rapid and accurate pressure settings, the heat sealing clamps slowly approach and seal adjacent samples, so that a short sealing time can be accurately reproduced. The heat sealing time can be set arbitrarily according to different testing requirements.
Foot Switch Operation
Press the foot pedal switch, the sample will be pressed, and its heat sealing time is determined by the pressing time of the foot pedal switch. Release the foot pedal switch, and the upper and lower heat sealing knives separate from the pressing state, completing the heat sealing of the sample.
