The heating principle of a Lefu 1325-B4 Flatbed Laminator, also known as a hot roll laminator, involves the use of heat and pressure to bond the laminating film to the substrate material. Here’s how the heating process typically works:
LF1325-B4 Flatbed Applicator (1.3*2.5m)
Model: LF1325-B4 Flatbed Applicator
Max Lamination Width: 1300mm/51.18″
Max Lamination Length: 2500mm/98.42″
Max Lamination Thickness: 50mm/1.96”
Lamination Temp: 0~60°C/0~140°F
Roller Up and Down: Pneumatic Pressure.
Heating Elements: The Lefu 1325-B4 Flatbed Laminator is equipped with heating elements, usually located within the rollers or plates of the machine. These heating elements can be made of various materials, such as silicone or metal, that generate and distribute heat evenly across the rollers.
Temperature Control: The Lefu 1325-B4 Flatbed Laminator has temperature controls that allow the user to adjust and set the desired temperature for the laminating process. The temperature range can vary depending on the type of laminating film and the substrate being used.
Preheating Phase: When the Lefu 1325-B4 Flatbed Laminator is turned on and set to the desired temperature, the heating elements start to warm up. It takes a few minutes for the machine to reach the set temperature, ensuring that the rollers are properly heated.
Feed and Pressure: Once the Lefu 1325-B4 Flatbed Laminator is heated, the substrate material (such as paper or cardstock) is fed into the machine along with the laminating film. The rollers apply pressure to the materials, pressing them together against the heated rollers.
Activation of Adhesive: As the substrate and laminating film pass through the heated rollers, the adhesive layer on the laminating film is activated by the heat. This causes the adhesive to melt and become tacky, allowing it to bond with the substrate material.
Bonding and Cooling: The heated rollers apply continuous pressure on the materials, ensuring a firm bond between the laminating film and the substrate. As the laminated materials exit the machine, they start to cool down, which helps in the solidification and curing of the adhesive.
It’s important to follow the manufacturer’s instructions regarding temperature settings, material compatibility, and safety precautions when using a Lefu 1325-B4 Flatbed Laminator to ensure proper lamination and avoid any damage to the materials or the machine.
