The main components of sandwich panel line

• Uncoiling system: Adopting a dual coil design, it can simultaneously process two layers of metal panels, and is equipped with an automatic correction device to ensure smooth material transportation.
  

• Forming unit: The metal panel is pressed into the desired waveform through multiple rolling processes. Modern equipment adopts a servo control system, which can achieve rapid mold change and adapt to different plate types.
  

• Foaming/bonding system: For polyurethane sandwich panels, equipped with a high-pressure foaming machine; For rock wool/glass wool sandwich panels, an automatic glue spraying system is used to ensure bonding strength.
  

• Composite press: Adopting dual belt continuous press or segmented press, precise control of temperature, pressure, and speed parameters to ensure product quality consistency.
  

• Fixed length cutting: Equipped with high-precision flying saws or laser cutting systems, the cutting accuracy can reach ± 1mm, while achieving automatic waste recycling.
  

• Stacking packaging: A fully automatic stacking system that can be grouped and packaged according to order requirements, reducing manual intervention.

Technological Innovation Trends

• Flexible manufacturing: Through modular design, the same production line can quickly switch to produce sandwich panels with different core materials (polyurethane, rock wool, XPS, etc.).
  

• Energy saving and environmental protection: The new production line adopts a heat recovery system to reduce energy consumption; The exhaust gas treatment device ensures compliance with environmental standards.
  

• High speed production: The latest generation of production lines can reach speeds of 15-20 meters per minute, with a daily production capacity of over 5000 square meters.
  

• Quality inspection: Integrated online visual inspection system, automatically identifying surface defects, thickness deviations, and other issues to achieve closed-loop quality control.

Modern sandwich panel production lines not only serve the traditional construction industry, but their products are also widely used in:

• Cold chain logistics warehouse
  

• clean room
  

• mobile home
  

• Ship cabin
  

• Special fields such as high-speed railway station buildings

With the popularization of green building concepts and the development of prefabricated buildings, latest sandwich panel lines are continuously evolving towards greater efficiency, intelligence, and environmental friendliness, providing important support for building industrialization.
