Decoral System’s IR technology uses heat, pressure and decorated film to create decorative finishes on large or small three-dimensional objects such as parts, shelves, handles, knobs and welded parts, as well as medium-density fibreboard (MDF) and more.
Profiles are placed in a frame and covered with a decorated film preprinted with such effects as wood grain, marble or a brushed appearance. The film is sealed as the frame is closed, and air is blown in to stretch the film like a balloon. It is then heated and all of the air is vacuumed out, leaving the parts wrapped air tight by the IR film. The frame with the wrapped parts then slides into the oven until the profile reaches 392°F (200°C).
High-temperature MDF boards that have been previously powder coated with Decoral powders also can be decorated in a wood grain finish using IR technology. The process is especially suited for MDF kitchen cabinetry, offering decreased production costs, increased durability and greater variety than lamination, the company says.
