Impulse sealer There are four sealing methods depending on your purpose and usage. Sealers
refer to machines in general that seal the opening or loose ends of plastic-

called heat sealers.
Heat-sealing technologies for general use include the following:
1
Impulse sealer
2
Constant heat sealer
3
Ultrasonic sealer
4
High-frequency sealer
Van der Stahl Scientific products are mainly the impulse sealer in the above
categories. An impulse sealer heat-seals objects by sending high current on
impulse to a heater ribbon, equipped on the surface of the heat-sealing blade,
to generate heat that enables thermal-sealing through thermal conductivity.
The section to be sealed is placed between the heat-sealing blades, pressed,
and thermal-fused when current and heat are delivered on impulse* through
the heater ribbon. After the current stops, a cooling process is necessary
during which the pressure is maintained.
*
The name “impulse sealer” is derived from the fact that the current and heat
are delivered on impulse, or instantaneously.
Temperature sensor A temperature sensor is installed under the heating element, directly measuring
heat temperature.
Lever sponge position This is the lever position of when the machine is in the vacuuming mode. The
sponge rubbers clamp a pouch while vacuuming.
Lever upper position This is the lever position of when the pressure lever is open (initial position).
Lever lower position This is the lever position of when the pressure lever is closed to perform sealing.
