Principals of Heat Sealing
Heating System
The Heat required for the welding operation is created electrically by hot air or hot wedge. Both methods
apply heat to the material to be welded.
Speed
The Speed of the Weld Rollers determines the amount of time the heat is applied to the material being
welded. The slower the speed setting, the more the material will be heated. The faster the speed setting,
the less the material will be heated. To achieve the best weld, a minimal amount of heat should be ap-
plied to the material while still achieving a full weld. Too much heat will cause distortion of the material;
while not enough heat will prevent the material from welding.
Pressure
The pressure of the weld roller is the final step when creating a weld. The pressure of the weld roller
compresses the heated material together completing the welding process.
Summary
When heat sealing, the correct combination of heat, speed, and pressure will allow you to achieve a
properly welded seam.
ALWAYS PERFORM A TEST WELD!
