Polyurethane Sandwich Panel Production Line: An Efficient and Energy-Saving Manufacturing Tool

Overview of Polyurethane Sandwich Panel Production Line

The polyurethane sandwich panel production line is key equipment for manufacturing polyurethane edge-sealed rock wool composite insulation panels. This type of equipment typically comprises multiple precision components, including a stacker, double-belt conveyor, polyurethane foaming machine, composite machine, cutting machine, and packaging machine. It can achieve full-process automated production from raw material feeding to finished panel output.

High Efficiency and Energy Saving

The polyurethane sandwich panel production line adopts a high-power, low-energy consumption design, with rapid response actions and low energy consumption. The energy consumption of Zhejiang Jinggong's polyurethane sandwich panel production line is equivalent to 40% of similar products. 

It features a fully enclosed internal insulation design, reaching the production process temperature within one hour after the heating and insulation system starts at room temperatures above 5°C. This energy-saving feature not only reduces production costs but also decreases energy consumption, aligning with the concept of green and environmentally friendly production.

Precision Control

The polyurethane sandwich panel production line is equipped with a precise servo lifting mechanism, allowing for flexible control over the thickness of the panels. Customers can easily change or adjust the thickness of the panels according to actual needs without concerns about the hydraulic system’s adjustments, leaks, and maintenance. This precise control capability ensures the stability and consistency of product dimensions, meeting the diversified requirements for panel thickness in different application scenarios.

High Degree of Automation

The polyurethane sandwich panel production line has a highly integrated and interconnected control system, centralizing all control points in the main control center. It enables parameter linkage and fault self-diagnosis for the entire line control, as well as remote control. The high-level automation control system not only improves production efficiency but also reduces labor costs and human operational errors, ensuring the stability and reliability of product quality.

Strong Adaptability

The equipment has strong adaptability and can produce various types of sandwich panels such as roof sandwich panels, wall sandwich panels, and cold storage sandwich panels. The internal core layer can also be chosen according to customer requirements, including polyurethane, rock wool, glass wool, and other varieties. The modular whole-line design concept allows the components of the polyurethane sandwich panel production line to be fully compatible and freely combined. Different combinations and configuration selections quickly meet the personalized production needs of customers.

Production Process Flow of the Polyurethane Sandwich Panel Production Line

Feeding and Glue Application

The finished rock wool board is conveyed into the glue application machine by a roller conveyor. The glue application machine has continuously rotating rollers equipped with flame-retardant polyurethane adhesive. When the rock wool board passes through the glue application machine, it achieves uniform glue coating on its lower surface.

Polyurethane Foaming and Composite

The rock wool board with glue applied is conveyed into the continuous production line of the polyurethane board, sequentially undergoing processes such as pouring, foaming, and curing. During this process, the liquid polyurethane evenly covers the upper and lower surfaces of the rock wool board and penetrates into it, forming a continuous closed-cell structure polyurethane waterproof isolation layer. Meanwhile, the self-adhesive property of polyurethane allows it to bond tightly with the rock wool board, forming an intruding physical interlock.

Cutting and Finished Product

The cured composite panel undergoes a cutting process, cut to predetermined dimensions to form standard polyurethane edge-sealed rock wool panels. The final panels are flat with precise dimensions, meeting the high standards of construction requirements.

The high efficiency, energy saving, precision control, high degree of automation, and strong adaptability of the polyurethane sandwich panel production line give it a significant competitive advantage in the market. With the continuous improvement of building energy-saving standards and the increasing demand for green buildings, the market demand for polyurethane edge-sealed rock wool composite insulation panels will continue to grow. 

The advanced performance of the polyurethane sandwich panel production line can meet the market demand for high-quality and high-performance insulation materials, bringing higher production efficiency and lower production costs to manufacturing enterprises. Additionally, the flexible configuration and wide applicability of the equipment allow it to expand into more application fields such as cold chain logistics, warehousing, and cold storage, further broadening market prospects.

In summary, the polyurethane sandwich panel production line is key equipment for manufacturing high-performance insulation materials. Its efficient, energy-saving, and precise production characteristics provide strong support for the development of building energy conservation, with tremendous future market potential.
