Model 4200 Series Laminator Manual
Operation II

  1. Shutting down after hot lamination
    1. After laminating with the rollers at an elevated temperature, it is a good idea to let the rollers cool to below 60°C before turning off the power.
    2. Press the COLD button. The temperature will gradually fall and the motor will keep turning. When the temperature falls to 60°C the motor will automatically turn off.
    3. Turn off the power switch.
    4. Selecting COLD mode and allowing the rollers to drop in temperature before turning off the machine will significantly increase the life of the rollers.
Laminating Temperature and Speed

When you are laminating a low temperature heat activated protective film onto a new substrate, a good starting point is the HOT pre-set function. With it´s combination of temp = 90°C and speed = 5, the HOT function should give good enough results that you can easily adjust the speed and/or temperature to achieve excellent lamination every time. The following "adjustment schedules" should help you zero in on the best combination of speed and temperature for you particular application.
  1. Adjusting laminating speed to compensate for changes in the thickness of the film or substrate.
    1. With 80 micron film as the standard, a change in 20 microns of thickness corresponds to 1 unit step of speed. If you set up you lamination process based primarily on 80 micron film with a given substrate, switching film thickness will require that you decrease lamination speed by 1 step from the standard speed of 5 for every 20 microns increase in film thickness.
    2. With 100 micron paper as the standard, a change in 25 microns of thickness corresponds to 1 unit step of speed. If you set up you lamination process based primarily on 100 micron paper, switching paper thickness will require that you decrease lamination speed by 1 step from the standard speed of 5 for every 25 microns increase in paper thickness.
  2. If the combination of film and paper is thinner than 1 step or thicker than 4 steps, adjust the laminating temperature using the following chart.
Change of step according to temperature
Temp(°C) 70 80 90 100 110 120 125 130 135 140 150
Step -4 -2 standard +1 +2 +3 +4 +5 +6 +7 +8

Confusing? Not really. Consider the following example:

EXAMPLE: If you want to laminate 125 micron film and 150 micron paper at a temperature of 100°C
  • Temp: add 1 step to go from 90°C standard to 100°C (see table above) +1
  • Paper: subtract 2 speed steps to compensate for a 50 micron increase in paper thickness above the 100 micron standard -2
  • Film: subtract 2.25 steps for increasing the film thickness by 45 microns -2.25
  • Total compensation is -3.75 steps. Round up to 4 steps and subtract from the standard speed (5) to yield a final speed of 1
