Description of operation:
The SD type impulse sealers have two sealing wires. The sealing wires are located next to each other parallel. The width of them is 5 mm. When it is needed, one of the sealing wires can be switched off separately. The safety knife is running between the two sealing wires.
Attention! When you use the two parallel sealing wires, the machine is ideal for the safe closing of pouches or bags, e.g. for powders or liquids. When you produce pouches or bags, only one sealing wire should be used.
The operation of the machine is very easy. The sealing bar can be closed by foot pedal or by hand. The sealing bar stays closed till the sealing and cooling time which was adjusted earlier, and then after the sealing is ready, the sealing bar opens automatically. Thanks to the fact that the sealing and cooling time can be adjusted separately, the sealing welt is very strong and resistant. The sealing done under big pressure makes it possible that even crinkled materials can be closed safely and smoothly. The unnecessary foil above the sealing welt can be eliminated with the integrated safety cutting knife easily and quickly.
