A fully automatic sandwich panel machine typically consists of multiple functional modules, including an automatic feeding system, panel pre-processing unit, core material filling device, hot pressing forming system, automatic cutting machine, and finished product stacking device. These modules are seamlessly connected through an intelligent control system, forming a complete assembly line that can operate 24 hours a day without interruption, with a daily production capacity of 5000-10000 square meters.

Core technology composition and working principle

• Automatic feeding system
  The starting point of a fully automatic sandwich panel machine is an efficient feeding system. Metal coils (usually color steel plates, stainless steel or aluminum plates) are unfolded by an automatic unwinding machine, and after the internal stress is eliminated by a leveling machine, they enter the cleaning and drying process. This process is completely controlled by PLC to ensure a clean and pollution-free surface of the panel, providing ideal conditions for subsequent bonding processes.

• Core material processing unit
  According to product requirements, the system can automatically switch between different core materials, such as polyurethane (PU), rock wool, glass wool, or EPS. The core material is quantitatively dispensed through precise measuring devices, and some high-end models are also equipped with core material online foaming technology to achieve on-site foaming and filling of polyurethane, ensuring that the core material is evenly distributed without voids.

• Composite and Forming System
  This is the core part of the production line, including the glue coating machine, pre press machine, and hot press machine. The specially designed double-sided adhesive coating device ensures even distribution of adhesive. The pre press machine preliminarily fixes the position relationship between the panel and the core material, and then enters the hot pressing forming section. The hot press adopts zone temperature control technology, with a temperature accuracy of ± 1 ℃ and a pressure uniformity error of no more than 2%, ensuring the bonding strength and flatness of the product.

• Fixed length cutting system
  Equipped with high-precision servo controlled flying saws or laser cutting devices, the cutting accuracy can reach ± 0.5mm. The advanced visual recognition system can automatically identify and mark defects in the board, and some high-end models also have automatic trimming and chamfering functions.

• Intelligent stacking and packaging
  Finished boards are stacked by robots or automatic stackers according to preset programs, equipped with automatic counting and coding systems. Some production lines also integrate automatic packaging machines to package finished products with protective film or cardboard, reducing transportation damage.

Technological innovation and advantageous characteristics

• Intelligent control system
  Modern fully automatic sandwich panel machines adopt industrial design concepts to achieve the following functions:
  Real time monitoring and recording of production data
  Adaptive adjustment of process parameters
  Equipment status warning and remote diagnosis
  Energy consumption optimization management

• Energy saving and environmentally friendly design
  The new generation of devices has significant improvements in energy consumption:
  The hot pressing system adopts an efficient insulation design, which increases the thermal energy utilization rate by 40%
  The waste recycling device can process scrap materials with a recovery rate of over 95%
  The exhaust gas treatment system complies with international environmental standards

• Multi functional adaptability
  One device can produce multiple types of sandwich panels:
  Thickness range: 30-200mm (customizable)
  Panel material: metal PVC、 Fiber cement, etc
  Core material types: PU, PIR, rock wool, phenolic resin, etc
  Board type changes: flat board, corrugated board, customized irregular board

The products produced by automatic sandwich panel machines are widely used in:

• Industrial plants and storage facilities
  

• Cold storage and temperature controlled warehouse
  

• Cleanrooms and medical facilities
  

• Prefabricated buildings and temporary houses
  

• Ship cabins and vehicle interiors

The fully automatic sandwich panel making machine is leading the development of building material manufacturing towards intelligence, efficiency, and environmental protection, providing strong equipment support for the global construction industrialization process. With the advancement of technology, such equipment will continue to break through production capacity limits, reduce production costs, and promote the application of sandwich panels in a wider range of fields.
