Laminating Process

Lamination describes a cohesive substance bonding process whereby multiple layers of various large surface area materials come together, creating a fixed, inseparable bond between layers. There are different laminating processes available, both with and without the use of binding agents.
 

Laminating involves combining the various mechanical and thermal properties of the individual layers, which improves the properties in the final product. Laminating not only works on traditional laminate flooring, but can also be used with fabrics such as truck tarpaulins and foam. Here, the laminating process simply describes firmly joining several layers using a heat source, with or without adhesives, and is a common method found in manufacturing. The heat source required can be from both Krelus infrared heaters and hot air blowers from Leister. Leister experts explain below the benefits of infrared heaters and hot air blowers for laminating applications. The Leister process heat team helps users select the right technology and equipment.

Laminating composite panels with infrared

Infrared technology generally laminates different foams to each other or in combination with other materials. Thin decorative layers on the outside are permanently bonded to an often multi-layered core using heat-activated adhesive.
However, even PVC flooring, synthetic leather and other multi-layer decorative material can be made using infrared technology.

Laminating with hot air

Practical examples include kitchen countertops, furniture construction or laminate flooring. There are numerous configuration options.
In laminating processes with hot air, the surfaces of the materials to be joined are heated evenly. For this purpose, wide-slot nozzles are often used for uniform air and temperature distribution. This process is used on foams for upholstery in the furniture and automotive industry as well as in wood processing. Here, hard, washable and scratch-resistant cover layers are laminated onto the carrier plates to increase their resistance
