In the construction and insulation industries, PU (Polyurethane) sandwich panels have become essential for their excellent thermal insulation, lightweight properties, and structural strength. But how are these advanced panels manufactured?

In the modern construction and manufacturing industries, sandwich panels have become an essential material for providing insulation, strength, and durability. From industrial buildings to residential housing, these panels are used in a variety of applications. However, the production of sandwich panels requires sophisticated machinery, and selecting the right production line for your business can make a world of difference in terms of efficiency, cost-effectiveness, and product quality.

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.
