Metal sandwich panel machine is a highly automated and efficient professional equipment, specifically designed for producing sandwich composite panels widely used in the construction industry. The metal sandwich panel production line combines two layers of metal panels (usually color steel plates, galvanized steel plates, or stainless steel plates) with intermediate core materials (such as polyurethane, rock wool, glass wool) to form building materials with excellent thermal insulation, sound insulation, and structural properties.
Open book system
As the starting point of the metal sandwich panel production line, the unwinding system consists of a hydraulic loading truck, an unwinding machine, and a leveling machine. Modern equipment adopts an automatic centering device, which can process 3-5 tons of metal coils, with a maximum feed width of 1500mm, ensuring that the metal plates enter the production line smoothly.
Forming unit
The core components include a multi pass roll forming unit (usually 16-22 rolls), which uses precision molds to cold bend metal plates into the desired cross-sectional shape. High end equipment is driven by servo motors, with a molding speed of up to 15-25 meters per minute and an accuracy controlled within ± 0.2mm.
Adhesive coating system
Equipped with high-precision metering pump and spray/scraping device, polyurethane glue or other special adhesives can be evenly coated, and the coating amount is precisely controlled at 80-200g/m ² to ensure the bonding strength between layers.
Core material processing unit
Configure different processing equipment according to different types of core materials:
Polyurethane foaming system: using high-pressure foaming machine, mixing head temperature control ± 1 ℃, foaming density 30-50kg/m ³
Rock wool/glass wool processing: automatic cutting, dust removal, and paving system
Composite compression molding section
Multi layer hot press or double belt continuous press, working pressure 5-15 tons, temperature control range 50-200 ℃, ensuring a firm bond between the core material and the panel. Equipped with infrared or microwave curing systems to shorten production cycles.
Fixed length cutting system
Adopting servo driven hydraulic shears or circular saws, with a cutting accuracy of ± 1mm, equipped with automatic stacker cranes and packaging lines, the maximum processing length can reach 16 meters.
Production line speed: 8-25 meters per minute (depending on the type of core material)
Product thickness: 30-200mm
Panel thickness: 0.3-1.2mm
Daily production: 3000-8000 square meters (8 hours)
Installed power: 150-400kW
Control system: PLC+touch screen, partially equipped with MES system interface
In addition to traditional building enclosure systems, the new metal sandwich panel machinery can also be used to produce:
Clean room specific antibacterial sandwich panel
Fire resistant and insulated electrical panels for data centers
Cold chain logistics ultra-low temperature insulation board
Photovoltaic Building Integrated Special Panel
Select the appropriate level of automation based on product positioning
Consider the product upgrade requirements for the next 5 years
Pay attention to energy consumption indicators and environmental performance
Assess the R&D capabilities and after-sales service network of equipment manufacturers
Verify the brand and reliability of key components such as control systems and hydraulic systems
With the rapid development of green buildings and prefabricated buildings, metal sandwich panel manufacturing lines are evolving towards greater efficiency, intelligence, and environmental friendliness, providing the construction industry with high-performance composite material solutions.
