The Rock wool sandwich panel production line is a multi-functional automatic production line integrating mechanical, chemical, electronic control, hydraulic, pneumatic and temperature control technologies. It is comprised by uncoiling, laminating, cutting, forming , rockwool/EPS feeding,preheating, foaming , curing, cutting , cooling,stacking and conveying, packaging.
The main production and formation process is to spray the glue continuously on both sides of the roll formed sheet, then moving through the double belt parts at a constant speed to make it composite tightly. The panel length can be set according to production requirement. After cutting, these panels will be stacked by suction cups and stacked. This production line can produce various types of composite panels:
The facing material is formed steel plate, with an effective width of 1000mm; the plate type and lapping method can be customized according to customer requirements.
The production and forming process of the composite board involves placing rock wool in the middle of the already formed surface materials, continuously spraying and foaming polyurethane on both sides (for rock wool + PU composite boards), bonding with glue on the upper and lower parts, moving forward at a constant speed via crawlers, and undergoing polymerization reaction in the double crawlers to form a composite cured board. After the composite board is fully formed, it is randomly cut according to the preset required length, and the production line does not stop during the cutting process.
This production line is designed for manufacturing high-quality rock wool sandwich panels, while also supporting PU/PIR sandwich panel production through optional configuration. It integrates advanced technologies in roll forming, composite conveying, automation control, and modular system design to achieve flexible and efficient production.
The line adopts a high level of automation, utilizing an integrated control system that combines PLC, CNC servo, variable frequency drive (VFD), and hydraulic control technologies. Each unit is interconnected through a distributed control system, enabling centralized monitoring and precise coordination to ensure stable and continuous operation.
For rock wool panel production, the line can be equipped with specialized modules such as rock wool feeding, cutting, and lamella arranging systems, ensuring accurate material placement and consistent panel quality. For PU/PIR panels, an optional high-pressure foaming system can be integrated to enable chemical foaming processes.
The production line supports a variety of panel types, including metal-faced rock wool wall panels, roof panels, and cold storage panels, as well as PU/PIR composite panels, meeting diverse construction and industrial requirements.
With a production speed of 2–10 m/min (stepless adjustable), the line delivers high efficiency and can achieve an annual output of up to 1,000,000 square meters (based on 250 working days and 10 hours per day).
The system is designed for ease of operation. Through a user-friendly human-machine interface (HMI), operators can input production parameters such as panel specifications and cutting length to realize fully automated production once materials are prepared.
By optimizing automation and system integration, the production line typically requires only 7–8 operators, significantly reducing labor costs while maintaining high productivity and operational stability.
Key structural components, such as the double belt system and crawler frame, are processed using large-scale CNC gantry machining centers. This ensures high precision, with crawler flatness controlled within 0.03 mm, resulting in superior panel quality and dimensional accuracy.
