The composite production line of color steel rock wool board integrates multiple advanced technologies to ensure excellent performance in production efficiency and product quality.

• Highly automated control system: Modern production lines use PLC control systems and human-computer interaction interfaces to achieve integrated control of the entire line, with a running speed of up to 15-30 meters per minute. The main control center centralizes all control points and has parameter linkage and fault self diagnosis functions. Some high-end equipment also supports remote monitoring and maintenance.
  

• Modular design concept: The equipment adopts a modular assembly structure, and key components such as roller sets are optimized through PEM finite element analysis to ensure stability and durability. This design facilitates quick replacement of molds and adjustment of parameters. A production line can produce various products such as roof sandwich panels and wall sandwich panels of different specifications through simple switching.
  

• Energy saving and environmental protection technology: The advanced production line adopts a fully enclosed internal insulation design and a low-energy consumption system, with energy consumption only 40% of similar products. The unique heating and insulation system can quickly raise the temperature in an environment above 5 ℃, reaching the process temperature within 1 hour without the need for additional insulation workshops.
  

• Precision forming technology: equipped with servo drive system and precision guiding mechanism to ensure the accuracy of sheet metal forming. The precision servo lifting mechanism without hydraulic pressure makes the adjustment of sheet thickness more convenient, avoiding hydraulic system leakage and maintenance problems.

A complete color steel rock wool board composite production line consists of multiple functional modules, which work together to complete the entire process from raw materials to finished products.

Main equipment composition

• Uncoiling and leveling system: including steel coil support frame, uncoiler, and leveling machine, used to unfold color steel coil and eliminate internal stress in the material. High end equipment adopts an internal support type cutting rack and a feeding guide platform to ensure that the strip steel enters the main machine smoothly.
  

• Forming host: The core equipment consists of multiple sets of Cr12 or GCr15 alloy steel rollers, which are pressed into the designed shape through cold bending technology. Modular design molding machines are usually equipped with 7.5-55KW motor drives, and the molding speed can reach 16-20m/min.
  

• Rock wool conveying system: automatically delivers rock wool strips to the composite station according to the set specifications, including cutting, rotating 90 degrees, and other processing to enhance the performance of the board. Some equipment integrates conveying channels for other core materials such as glass wool and polyurethane.
  

• Composite system: The color steel plate is firmly bonded to the core material using thermosetting adhesive or polyurethane foaming technology. The high-end production line is equipped with a pentane multi-component high-pressure foaming machine, which can achieve free proportioning of 2-9 components.
  

• Cutting system: Fully automatic fixed length cutting device, usually equipped with double-sided alloy saw blades, with high cutting accuracy and smooth cutting edges. Advanced CNC systems can achieve diagonal cutting and irregular machining.
  

• Board stacking system: Automatically stacks finished boards neatly, reducing manual handling. Some production lines are equipped with automatic packaging equipment to directly complete product factory packaging.

Standard process flow

• Loading stage: The color steel coil is loaded into the unwinding machine through a hydraulic loading trolley, and after leveling, it enters the forming host.
  

• Forming stage: The steel plate is gradually formed into the desired cross-sectional shape through multiple rollers.
  

• Glue coating composite: The surface of the formed steel plate is automatically sprayed with adhesive and combined with precisely cut rock wool core material. The polyurethane edge sealing process is completed at this stage.
  

• Pressure curing: The composite board enters the pressure zone and the adhesive is completely cured under the set temperature and pressure.
  

• Fixed length cutting: According to the order requirements, the CNC cutting system accurately cuts the length of the sheet, with a smooth and burr free cut.
  

• Stacking packaging: Finished boards are automatically stacked, and some high-end production lines are equipped with film wrapping packaging machines to directly complete product packaging.
