In an automated environment you can choose to leave the spraying of PU foam to a robotic arm. Based on a computer file that is read in, it is possible to determine the spray pattern, speed of movement and spray intervals. FROTH-PAK is a quick-hardening polyurethane foam. After 30 seconds the eventual volume is already known and a new layer can be applied. The object can be built up or covered in foam. In this way, both 3D objects and flat shapes can be provided with an insulation foam.
