Gradient Heat Seal Tester, Brand Name : CELL INSTRUMENTS

We are offering gradient heat seal tester.
Gradient heat seal tester is professionally designed for the precise measurement of five groups of sealing temperature, time and pressure. Gradient heat seal tester is for the determination of the heat sealability of a surface, or sealant layer of films, laminates, composites and polymers etc.it conforms to standards of astm f2029, qbt 2358 and ybb 00122003.
Gradient heat seal tester 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.
Gradient heat seal tester features
1. five groups sealing temperature can be measured with one test
2. proximity and pressure sensor 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. independent heating of upper and lower sealing jaws
6. sealing jaw customization available in term of dimension, shape and surface
