The color steel rock wool sandwich panel assembly line is an intelligent production system that integrates mechanical, electrical, and automation control. It can produce high-performance building panels from color coated steel plates and rock wool core materials through continuous composite forming processes.
As the core material of modern building enclosure systems, color steel rock wool sandwich panels have become the preferred choice for industrial plants, commercial buildings, and public facilities due to their excellent fire resistance, insulation, and sound insulation performance.
The production line for color steel rock wool sandwich panels usually has a length of 45-100 meters and adopts modular design, which can achieve flexible production of various products such as roof sandwich panels, wall sandwich panels, and cold storage sandwich panels.
Highly automated: The entire line adopts a PLC control system to achieve full process automation from coil unwinding to finished product cutting, with a production speed of up to 3-25 meters per minute
Multi functional compatibility: Simply adjust to switch between producing sandwich panels with different core materials such as polyurethane (PU/PIR), rock wool, glass wool, etc
Precision control: The servo drive system ensures that the thickness tolerance of the board is controlled within ± 0.2mm, and the flatness of the board surface reaches the industry-leading level
Energy saving and environmental protection: The new production line reduces energy consumption by 60% compared to traditional equipment and is equipped with a waste gas collection and treatment system
A complete set of color steel rock wool sandwich panel assembly line includes multiple key functional modules:
Open book leveling system
The design of a dual roll machine enables non-stop roll changing, ensuring continuous production
Equipped with a precision leveling machine to eliminate internal stress in steel plates, the flatness of the plate surface reaches 0.5mm/m ²
Forming unit
Adopting a multi pass progressive forming process, the roller material is Cr12MoV alloy steel with a hardness of HRC58-62
The rapid mold changing system can complete plate type replacement within 15 minutes
Rock wool processing system
The 90 degree fiber steering device ensures that the rock wool fibers are perpendicular to the board surface, increasing compressive strength by 30%
The automatic glue spraying system uses PUR hot melt adhesive, with an accurate dosage of ± 5g/m ²
Composite unit
The pressure of the dual belt press can reach 0.5MPa, and the composite temperature is stable at 160 ± 5 ℃
Equipped with an online thickness detector for real-time feedback adjustment
Polyurethane edge banding system (optional)
The high-pressure foaming machine injects polyurethane into the edge of the board to form a continuous sealing layer
Foam density controlled at 40 ± 2kg/m ³, closed cell rate>90%
Fixed length cutting system
Servo driven flying saw, cutting accuracy ± 1mm
The maximum cutting length can reach 16 meters
Stacking packaging system
Automatic counting and sorting, the number of boards per stack can be set
Protective corner packaging to avoid transportation damage
The production of color steel rock wool sandwich panels adopts continuous composite forming technology, and the main process includes:
Pre treatment of color steel plate
The uncoiled color steel plate undergoes cleaning and passivation treatment to enhance adhesive adhesion
Surface tension testing ensures a minimum of 38mN/m
Plate forming
The upper and lower steel plates are pressed out of the required plate shape by the forming unit respectively
Common board types include flat, small ripple, V-shaped rib, hidden buckle, etc
Rock wool treatment and paving
After the rock wool board is divided into longitudinal and transverse strips, the fiber direction is perpendicular to the board surface through a flipping device
The automatic paving machine accurately places rock wool on the lower steel plate
Composite curing
The upper and lower steel plates are combined with rock wool under high pressure and high temperature, with a pressure of 0.3-0.6MPa
Using microwave heating technology, the curing time is shortened to 30 seconds
Polyurethane edge banding (optional)
Inject polyurethane mixture at the edge of the board, foam to form a continuous sealing layer
The edge width is usually 15-25mm
Fixed length cutting and stacking
Automatically cut according to order requirements, with a smooth and burr free cut
Automated stacking by robotic arm, with each stack height not exceeding 1.2 meters
Industrial buildings
Roofing and wall systems for large factories and logistics warehouses
Fire separation in clean workshops and explosion-proof areas
Public buildings
Energy saving enclosure structures for sports halls and exhibition halls
Fireproof and soundproof walls in hospitals and schools
Special applications
External wall insulation and fire prevention system of data center
Sound barrier structure of rail transit
Construction of low-temperature warehouses for cold chain logistics
