Description

Heat Seal Tester is for the determination of the heatsealability of a surface, or sealant layer of films, laminates, composites and polymers etc. How well the material heatseals is expressed quantitatively as seal strength as a function of the sealing conditions of temperature, time and pressure. Heat Seal Tester is professionally designed for the precise measurement of the three parameters of temperature, time and pressure in the heat seal process. Heat seal Tester conforms to standards of ASTM F***9, QB/T ***8 and YBB *******3.
 
Principle
Place a sample between two-heated sealing jaws of Heat Seal Tester with flat surfaces when the required temperature reaches equilibrium. The upper seal jaw, driven by a gas cylinder, is pushed down,  to exert a certain pressure on the sample and remain for some time. When the preset sealing time ends, the upper sealing jaw returns to its original position and the whole heatsealability testing process finishes.
 
Features
1.    7 inch TFT touching screen makes parameter setting and operation easy and convenient for Heat Seal Tester.
2.    PLC for precise dwell time and sealing pressure control
3.    P.I.D. for precise sealing temperature control
4.    Uniform heating by aluminum encapsulated sealing jaws and no inhomogeneous heating
5.    Multiple groups of test parameters can be saved to reduce setting time and eliminate human error
6.    Independent heating of upper and lower sealing jaws on the model of Heat Seal Tester.
7.    Sealing jaw customization available in term of dimension, shape and surface
