Electromagnetically powered sealers are safe to operate. Through the use of a special mechanical linkage, the high pressure required for sealing is not developed until the sealing jaws touch, preventing accidents. The sealing surface of the heater jaw is normally cool since it is energized for a fraction of a second only when the jaws are completely closed. This safety feature results in greater economy since electricity is consumed only during the sealing cycle.
Inexperienced workers quickly learn to operate these electromagnetically powered sealers. The operator simply inserts the open end of the pouch between the sealing jaws and strikes a switch. The Heat and Dwell time cycles are adjustable and once they are set no operator adjustment is required. The sealing jaws open automatically when the cycle is completed.
Production speeds vary according to the type and thickness of the film heat sealed and the skill of the operator. Speeds of up to 20 cycles per minute are attainable when sealing 1 mil polyethylene film. A 1/8" wide air tight, water tight ribbon seal is standard.
Time Control: This time oriented system is standard on all iSeal™ Heat Sealers. Heat and Dwell times are set quickly and easily by adjusting two dials. This feature permits selection of the proper impulse duration and jaw closed time for a wide range of films of different composition and thickness. All controls are built into the chassis.
Additional features available:
Wider or Narrower Heater Element: for special applications.
Water Cooling ("WC"): to make fast consistent quality heat seals.
Temperature Control: This is recommended when sealing heavy gauge materials on a production basis, or very high temperature materials in the 400ºF and higher range. This system uses a special high response temperature probe located in a second set of simulated sealing jaws to sense the temperature of the heater element. The heat starts when the preset maximum temperature selected is reached. The sealing jaws remain closed, cooling the seal under pressure, until the temperature drops to the preset minimum temperature at which point they open automatically.
