Ɣ
Set the cooling temperature depending on the film
Cooling process is important when using an impulse sealer. After the
film is heated, the film must cool with the frame and pressure lever in
the closed position. Setting the cooling temperature excessively low
will decrease the work productivity. Set the cooling temperature that is
suitable for each film.
Ɣ If there is a malfunction in the temperature sensor
The temperature sensor is designed to monitor and control heating
temperature by directly measuring the heater temperature. Therefore,
the machine will not operate when the sensor tip is not positioned
correctly or the sensor is disconnected.
When replacing the consumable parts such as heating element or the
temperature sensor, please be sure to position the temperature sensor
correctly.
Ɣ Dust in the sealing area
Dust will prevent attainment of a smooth seal. It could also cause
damage to heating element and/or other routine maintenance parts.
Before using the machine, clean the sealing area.
Ɣ When fluoro glass sheet, silicone rubber becomes
damaged
The fluoro glass sheet, silicone rubber will start to wear with use. Once
they are damaged, it will be difficult to achieve smooth and strong
seals. Thoroughly read how to replace the parts and be careful when
doing so.
Ɣ
LOS-NT/NTW series are impulse sealer
Van der Stahl Scientific sealers utilize an impulse heating system,
meaning that the heater section does not become hot simply because
the power has been turned on.
It is programmed so that the heating element is heated only during the
heating cycle, after a sensor switch and micro processor have been
activated.
Please note, however, the sealing section may become hot after
prolonged operation.
Ɣ
Run test trials first before beginning operation
Achieving a superior seal with an impulse sealer is determined by
heating / cooling. Depending on the type of film being used and the
contents of the bag, heating / cooling conditions may drastically differ.
Find the optimum sealing conditions by conducting seal tests before
proceeding.
