Application and Brief Intro HST-01 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. HST-01 Heat Seal Tester is professionally designed for the precise measurement of the three parameters of temperature, time and pressure in the heat seal process. HST-01 Heatsealability Tester conforms to standards of ASTM F2029, QB/T 2358 and YBB 00122003. Principle Place a sample between two-heated sealing jaws of HST-01 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. ASTM F2029, QB/T 2358, YBB 00122003
Instrument structure: The structure of the heat-sealing tester is composed of 4 parts: pneumatic drive system, heat-sealing equipment, temperature adjustment system and time adjustment system. Pneumatic drive system: It includes pressure gauge, guide stick, cylinder, pneumatic valve, pressure regulating handle and so on. You can pull the pressure-regulating handle outward, rotate to the right side to adjust the heat sealing pressure to a high value, and rotate to the left side to reduce it. After setting the pressure, please press the handle to the side of mainframe to lock the air pressure. Heating-seal device It is composed of the upper and lower heat-sealing sticks, of which the upper one is connected with a cylinder. There is an insulating plate in the upper part, which can prevent heat transmit to the cylinder. The heat-sealing stick is made of aluminum, and the center is heater. There is a silica gel plate in the upper part of the lower heat-sealing stick, which can mitigate pressure impact during heat sealing. Temperature measurement system was installed at the back of the heat-sealing stick. Temperature adjustment system: The upper temperature controller controls the temperature of upper heat-sealing stick, and the rear temperature controller controls the temperature of lower heat-sealing stick. The temperature can be set at will through adjusting the button on the dial plate. Time adjustment system: Time adjustment system: The heat-sealing time can be set at will through adjusting the button on dial plate. The setting scope of time is 0.01s to 999.9h. Press the foot switch under the manual state, and the heat-sealing stick will be pressed together. Under the automatic state, the press-fitting time of upper and lower heat sealing sticks are controlled by a timer automatically, it can automatically recover later. The unit of timer is 0.1 second in general. There is time adjusting button on the panel of the timer, and the heat-sealing time can be adjusted at will.

Heat Seal Tester is professionally applicable to the determination of heat-sealing temperature, dwelling time and the heat-sealing pressure which are references to the production of aseptic bag, food, pharmaceutical, daily chemicals, package and raw material. Features Micro-computer control tests. Touch interface is easier to operate. Self-innovated "constant temperature control" system improves the accuracy of temperature. The synchronous circuit of single bottom cylinder ensures the balance of pressure. Aluminum-sealing jaws provide even and uniform temperature for different sealing surfaces The upper and lower jaws controlling the temperature independently and the super-long thermal cover can meet different needs. Dual switch modes of manual and foot make the safety and convenience. Micro-printer embedded can get the results quickly. The design of anti-scald and leakage protection is more secure to test. Principle HST-H3 Heat-Seal Tester is composed of upper and lower heat sealing jaws. Before the test, preset the values of heat-sealing temperature, pressure and dwelling time, then place the specimen in between the upper and lower jaws and press start button. The whole sealing process can be finished automatically.
