II. Production Workflow

Lifting trolley feeding → Uncoiling → Film Laminating → Sheet Forming → Rockwool Feeding → Sheet Preheating → Foam Molding → Double-Conveyor Composite Forming (Insulation) → Band Saw Cutting → High-Speed Roller Conveyor → Curing → Stacking → Packing

III. Composition of the Composite Panel Production Line

This composite panel production line mainly consists of the following equipment: steel coil uncoiling system, film laminating and cutting system, sheet forming system, rockwool feeding system, dust removal system, preheating system, foaming system, double-conveyor system, band saw cutting system, cooling and curing system, stacking system, and packing system.

III. Main Features and Advantages of the Production Line

The composite panel continuous production line integrates mechanical, electrical, hydraulic, and polyurethane (chemical) polymerization reaction technologies into a fully automated continuous production line composed of multiple units. This production line adopts advanced domestic and international roll-forming technology, polyurethane (chemical) foaming technology, composite conveying technology, CNC servo control technology, variable frequency vector control technology, hydraulic control technology, and automatic stacking technology. Only 8–10 operators are required for its normal operation. The features of the production line include:

High Degree of Automation: The machine utilizes a comprehensive set of self-developed computer-integrated control technologies, including CNC servo control, variable frequency vector control, and hydraulic control. It implements distributed integration and centralized control of all individual units, and adopts automatic random-length cutting, ensuring constant and uniform operation across all functional sections, thereby achieving fully automated production.

High Production Efficiency: The production speed can reach 3–10 m/min (infinitely adjustable based on panel forming requirements), with an annual production capacity of up to 1,000,000.00 square meters.

Easy Operation: Using comprehensive computer-integrated control technology and a human-machine interface (HMI), operators simply input the required operational parameters for each functional section and the panel cutting length (once all raw materials and production preparations are ready) to initiate automatic production.

Low Production Cost: With the high level of automation, the entire production line requires only 8–10 operators to complete the entire production process and maintain normal equipment operation. The high-efficiency production forming speed significantly reduces production management and labor costs.

Cost-Effective Investment: The technical performance indicators of this production line meet the advanced levels of similar foreign products. It can fully replace imports while being priced far lower than comparable foreign equipment, saving substantial foreign exchange for the country and providing significant investment savings for customers.
