Novel Application of SST Cold Spray Technology in High Volume Production of Polyamide (PA) thermal barrier profiles for Industrial and Residential Window and Facade Manufacturing

Thermal efficiency is one of the most important aspects of industrial and residential construction. Aluminum is by far the most widely used material for window profiles used in windows and facades frames. The production of aluminum and other materials profiles for windows and facades is a multibillion-dollar well-established global industry. The major downside to aluminum is its low thermal insulation capability. For decades, one of the most commercially viable and popular solutions has been the addition of a thermal barrier in the form of a profile, made of polyamide (PA), inserted between the outer and inner parts of the aluminum frame. Polyamide has excellent thermal dimensional stability, ensuring thermal barrier profiles that offer unlimited possibilities in terms of windows aesthetics and design. Despite the advantages as the best polymer for aluminum assembly, electrostatic powder coating, and anodizing processes, the use of Polyamide profiles has opportunities for improvement in areas such as finishing as well as reliable building adhesion to other substrates. In this presentation we will talk about the ability of low-pressure cold spray to produce controlled coating of polyamide profiles with proprietary powdered materials in a volume production environment to improve their performance.
