GHS-01 Heat Seal Tester

Application
A Heat Seal Tester is a device used in the packaging industry to evaluate the
heat-sealing properties of various materials, such as films, laminates, and
other packaging components. The heat seal strength and integrity of these
materials are crucial to ensure the quality and effectiveness of packaging for
products like food, pharmaceuticals, electronics, and more.
The tester works by applying a certain heat and pressure to a sample of the
material being tested for a certain time interval, simulating the conditions
under which heat seals are formed in the packaging process. The heat, pressure,
and time settings can be adjusted to mimic different sealing conditions, which
allows manufacturers to determine the optimal parameters for achieving strong
and consistent seals.
The term "gradient" in Gradient Heat Seal Tester refers to the ability of the
device to create a controlled temperature gradient across the sealing area. A
Gradient Heat Seal Tester can also be understood as a Multi-Station Heat Seal
Tester, which means tests can be run at different temperature settings
simultaneously. This reduces the waiting time between tests and increases the
overall efficiency of the testing process.

Technical Features
The key to a heat seal tester is its stability and accuracy in time,
temperature, and pressure. GHS-01 Gradient Heat Seal Tester ensures good
sealing results with our state-of-art design, and it can realize five groups of
sealing temperatures simultaneously.
1. Both the upper and lower jaws are made of aluminum and independently heated
so that heat loss is maximumly eliminated in sealing and temperature smoothness
is ensured.
2. First class P.I.D. (proportional integral derivative) temperature controller
realizes precise temperature control and efficient heating.
3. Combination of accurate timer and proximity sensor realizes simultaneous
seal start time with jaw movement.
4. Unform sealing pressure by the three-way guided sealing bar.
5. User protection designs, such as anti-scald front cover, manual and foot
switch, etc.
6. Seal jaw customization available in terms of dimension, shape, and sealing
surface/patterns.
7. More gradient temperatures of upper and lower heating can be customized.
