English
The Duwell Polyurethane Sandwich Panel Production Line is an advanced and fully automated system designed for manufacturing high-quality insulated sandwich panels with excellent thermal performance and structural strength. The panels consist of two metal sheets (steel or aluminum) and a rigid insulation core such as polyurethane (PU), PIR, or rock wool, making them ideal for industrial, commercial, and agricultural buildings.
Designed for continuous and stable operation, this sandwich panel production line ensures accurate thickness control, strong bonding between metal skins and insulation core, and consistent surface quality. It is suitable for large-scale insulated panel manufacturing projects with high requirements for efficiency and product uniformity.
A sandwich panel production line is a highly efficient and fully automated manufacturing system
designed for producing insulated sandwich panels used in industrial buildings, warehouses,
cold storage rooms, clean rooms, commercial facilities, and residential construction projects.
The production line combines advanced roll forming technology, polyurethane (PU/PIR) foaming systems,
laminating units, heating systems, and automatic cutting equipment to produce high-quality insulated panels
with excellent thermal and structural performance.
Modern sandwich panel production lines are widely used for manufacturing：
roof panels
wall panels
cold room panels
garage door panels
and industrial insulated panels.
These production systems can process galvanized steel, pre-painted steel, aluminum sheets, stainless steel,
and other metal materials combined with insulation cores such as polyurethane (PU), polyisocyanurate (PIR), EPS, or rock wool.
The complete sandwich panel production line is designed with precision engineering, stable operation, and intelligent
PLC control systems to ensure high production efficiency, accurate panel dimensions, and consistent insulation quality.
The line can produce various panel thicknesses, widths, joint profiles, and surface patterns according to customer
requirements and international standards.
Our sandwich panel production lines feature advanced automation technology, energy-saving systems,
and heavy-duty machine structures, providing reliable long-term performance with low maintenance costs.
The machines are suitable for continuous large-scale industrial production and customized panel manufacturing solutions.

Advantages of Sandwich Panel Production Line
The sandwich panel production line offers excellent insulation performance, lightweight structure,
fire resistance, sound insulation, and fast installation benefits. Compared with traditional building materials,
insulated sandwich panels help reduce energy consumption and improve construction efficiency.
This production line functions as a complete polyurethane sandwich panel manufacturing line, integrating roll forming, high-pressure foaming, heating conveyor, panel curing, and servo cutting into one continuous process. The optimized line structure guarantees stable foaming performance and reliable panel quality during long-term operation.
By adjusting the forming and side-stop modules, the same polyurethane sandwich panel line can produce panels with different thicknesses and profiles, providing flexibility for various building and insulation requirements.
