Adjusting the Seal bar Pressure
Note: For cross seal bar see: symptoms and adjustment of cross seal bar.
WARNING:
Wait until the heat sealing bar has cooled enough (approx. 3
hours) before servicing seal bars or the areas near the bars. If
maintenance on the machine is absolutely necessary before sealing bars
have had a chance to cool down, the person performing the maintenance
must use safety equipment approved by OSHA or local law to protect
against burns.
Loosen nut above clevis on each cylinder rod and rotate rod cylinder
counter clockwise ¾ turn. Take a sample set of plastic layers used in
production and perform a seal. What we are trying to determine is a
sealing pressure point. The object is to get the heated seal bar sealing the
plastic evenly with as little force as possible.
Note: We are only adjusting the cylinder rods, not shimming.
Once you have example A, try to decrease pressure by a ½ turn on both
cylinders and see if you get example B. If not, keep decreasing until you
see example B If so, then increase pressure ½ turn and tighten the cylinder
rod nuts and you are finished.
