PU Panel Line

The PU Panel Line, especially the polyurethane composite board production line, is a highly automated industrial system specifically designed for producing polyurethane composite boards.

The working principle of the PU Panel Line is mainly based on the mixing and foaming curing process of polyurethane resin raw materials, curing agents, foaming agents and other materials.

Technological Process:

• Raw material preparation and ratio: Prepare polyurethane resin raw materials, curing agents, foaming agents, etc. according to specific ratios.
  

• Mixing and pouring: These raw materials are accurately measured by the pouring machine's metering pump and sent to the high-speed mixing head for uniform mixing, and then continuously coated on the upper and lower base materials (such as color steel plates).
  

• Foam curing: The coated surface material enters the double belt machine and undergoes foam curing between the heated upper and lower tracks.
  

• Forming and cutting: The foam cured sandwich panel is processed by a trimming device to obtain accurate width dimensions, and then cut according to the set product length using a fixed length tracking saw cutting machine.

The PU Panel Line mainly consists of the following equipment:

• Uncoiler: used for unwinding raw materials.
  

• Roll forming machine: Processing raw materials into shapes.
  

• Preheating roller conveyor: Preheating the material to improve the foaming effect.
  

• Foaming machine: responsible for injecting the mixed polyurethane raw materials into the double-layer board.
  

• Fabric machine: used for evenly coating polyurethane raw materials.
  

• Double track machine: provides the temperature and pressure environment required for foaming and curing.
  

• Cutting machine: Cut according to the length requirements of the product.

In addition, it may also include auxiliary equipment such as roller conveyors, trimming devices, and automatic palletizers.

The PU Panel Line has the following technical characteristics:

• Highly automated: The entire production line adopts integrated technology of mechanical, electrical, and hydraulic systems, achieving full process automation from raw material preparation to finished product output.
  

• Efficient and energy-saving: The production line is designed reasonably, which can fully utilize raw materials, reduce energy consumption, and improve production efficiency.
  

• Stable product quality: Through strict quality control standards and testing nodes, we ensure the stable and reliable quality of the produced polyurethane composite boards.

Polyurethane composite panels are widely used in construction, cold chain, furniture and other fields due to their excellent thermal insulation performance. Especially in the field of construction, polyurethane composite panels serve as insulation materials for walls, roofs, and floors, with advantages such as light weight, high strength, corrosion resistance, and easy construction.

With the advancement of technology and the strengthening of environmental awareness, the PU Panel Line is developing towards a more intelligent and green direction. For example, by integrating DCS systems to achieve real-time monitoring and intelligent control, production efficiency and product quality can be improved; Using bio based materials to replace some petroleum based materials to reduce environmental pollution; And adopting more environmentally friendly foaming agents and processes to reduce VOC emissions.

The PU Panel Line, as an efficient, energy-saving, and environmentally friendly industrial system, plays an important role in fields such as construction and cold chain. In the future, with the continuous advancement of technology and the expansion of application fields, the PU Panel Line will usher in a broader development prospect.
