GHS-02 Heat Seal Tester

Application
A Heat Seal Tester is a crucial apparatus in the packaging industry, employed
to assess the heat-sealing characteristics of diverse materials including
films, laminates, and other packaging components. The strength and integrity of
heat seals in these materials play a pivotal role in ensuring the quality and
efficacy of packaging for products ranging from food and pharmaceuticals to
electronics and more.
The functioning of this tester involves the application of specific heat and
pressure to a sample of the material under examination for a predetermined
duration. This process emulates the conditions in which heat seals are
generated during packaging procedures. The ability to customize the heat,
pressure, and time settings allows manufacturers to replicate varied sealing
scenarios, enabling them to identify the optimal parameters for establishing
robust and consistent seals.
In the context of a Gradient Heat Seal Tester, the term "gradient" denotes the
device's capability to create a controlled temperature gradient across the
sealing zone. Alternatively known as a Multi-Station Heat Seal Tester, the
Gradient Heat Seal Tester facilitates concurrent tests at varying temperature
settings. This innovation effectively diminishes the waiting period between
tests, thereby enhancing the overall efficiency of the testing procedure.

Technical Features
The key to a heat seal tester is its stability and accuracy in time,
temperature, and pressure. GHS-02 Gradient Heat Seal Tester’s PLC control unit
and HMI touch screen, ensure 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
for optimal heating management.
3. Achieve accuracy with proximity and pressure sensor, ensuring controlled
dwell time and sealing pressure.
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.
8.Seamlessly connect through the RS 232 port and professional software
(optional).
