Sandwich panels are high-performance building materials made by bonding two metal sheets with an insulated core material. These panels are widely used in industrial buildings, warehouses, cold rooms, and prefabricated structures due to their strength and thermal insulation.

Setting up a sandwich panel production line is a long-term industrial investment. The quality of the machinery directly affects your production capacity, panel quality, labor cost, and return on investment for years.

In a sandwich panel production line, many investors focus on the double belt press, chemical dosing system, or roll forming stations. However, one of the most critical units that directly affects panel surface quality and line stability is often underestimated — the decoiler unit.
