Continuous PU Sandwich Panel production line technology represents a breakthrough in industrial manufacturing, offering a reliable and efficient process to produce high-quality sandwich panels. These panels, with their exceptional thermal insulation, strength, and lightweight properties, are integra

DBL is mainly used to overcome the expansibility of foaming and make it solid, and decide panel thickness and production speed. Side belt is overcome horizontal expansion and decide width of panel and guiding to the panels. As active running moulds, it avoids panel deformation and scratch and to ensure panels quality.
