We are pleased to share the successful installation and commissioning of a Decorative Wall Sandwich Panel Production Line in Uzbekistan. This project marks another important milestone for us in delivering complete, automated solutions for high-quality architectural wall panel manufacturing in Central Asia.

The newly installed line is designed to produce decorative metal siding panels with Rockwool insulation and PU foam edge sealing, meeting modern requirements for fire resistance, thermal insulation, durability, and aesthetic appeal. From raw material handling to final cutting, the entire system runs fully automatically under an advanced PLC and servo control architecture, ensuring stable output and consistent panel quality.

Project Overview

The mineral wool wall sandwich panel production line is engineered to manufacture decorative wall sandwich panels with:

• Panel thickness: 20 mm – 50 mm
• Effective panel width: 380 mm
• Insulation core: High-density Rockwool
• Edge sealing: Polyurethane (PU) foam with glue bonding

These panels are widely used for industrial buildings, commercial facades, prefabricated structures, and energy-efficient exterior wall cladding systems, especially in regions with strict fire safety requirements.

The total working length of the complete line is approximately 65 meters, with a maximum equipment layout width of 5 meters, making it suitable for medium-to-large scale industrial workshops.

Complete Line Configuration

This decorative wall sandwich panel production line with Rockwool insulation consists of the following major units:

1. Decoiler
   Designed for stable feeding of pre-painted metal coils (PPGI or PPGL), ensuring smooth and continuous material entry into the line.
2. Two Sets of Metal Embossing Machines
   These machines create decorative surface patterns on the metal sheets, enhancing both the visual appearance and structural rigidity of the exterior wall panels.
3. Exterior Wall Panel Roll Forming Machine
   Precisely forms the embossed metal sheets into the required panel profile with high dimensional accuracy and excellent surface protection.
4. Rockwool Feeding Table
   Automatically positions and feeds high-density Rockwool strips (density > 100 kg/m³) into the panel core area, ensuring uniform insulation thickness and tight bonding.
5. 3-Component Foam Machine (ISO / POLY / Glue)
   This system injects polyurethane foam and adhesive precisely along the panel edges, providing:
   • Strong edge sealing
   • Improved panel rigidity
   • Enhanced thermal performance
6. Rubber-Belt Lamination Machine with Edge-Sealing Side Belt
   Applies continuous pressure during lamination, ensuring full bonding between metal skins, Rockwool core, aluminum foil paper, and PU edge foam.
7. Servo Tracking Fly-Saw Cutoff
   Automatically cuts panels to preset lengths with high precision, without stopping the decorative wall sandwich panel production line.

Raw Materials Used

The rockwool sandwich panel production line is compatible with a wide range of commonly available construction materials, including:

• Metal sheets:
  • 0.21 – 0.35 mm PPGI or PPGL
• Insulation core:
  • High-density Rockwool strips (≥ 100 kg/m³)
• Edge sealing materials:
  • Polyurethane foam
  • Industrial bonding glue
• Backing layer:
  • Aluminum foil paper

This combination results in panels that offer excellent fire resistance, sound insulation, thermal efficiency, and long service life.

Automation and Control System

The entire automatic wall sandwich panel production line operates under:

• PLC centralized control system
• Servo motors for length tracking and cutting accuracy
• Multiple inverters for speed regulation
• Touchscreen HMI for easy operation and parameter adjustment

This control architecture allows synchronized operation of all machines, reduces manual intervention, and ensures stable production even during long continuous shifts.

• Length of Rubber-belt Laminator: 26.5m
• PU Foaming Machine: 3-Component
• Total line length: approx. 65 m
• Maximum line width: 5 m
• Cutting system: Servo tracking fly-saw
• Operation mode: Fully automatic

Introduction to the Finished Panels

The finished decorative Rockwool metal siding wall sandwich panels produced by this line combine architectural aesthetics with industrial-grade performance. The exterior metal sheet is processed by advanced embossing machines, creating a variety of decorative textures that enhance the visual appeal of modern buildings while maintaining excellent surface durability. With a standard effective width of 460 mm and a typical thickness of 50 mm, the panels are designed for both design flexibility and structural reliability.

At the core, high-density mineral wool (Rockwool) provides outstanding fire resistance, sound absorption, and thermal insulation, meeting stringent fire-safety requirements in European and international markets. The addition of PU foam edge sealing significantly improves panel integrity by sealing the side joints, reducing air leakage, eliminating thermal bridges, and increasing overall strength compared with pure mineral wool metal siding.

Manufactured using 0.23–0.35 mm Al-Zn coated steel or pre-painted metal, these panels offer excellent corrosion resistance and long service life, even in demanding outdoor environments. Lightweight yet rigid, they allow for fast installation, reduced structural load, and lower construction costs.

Thanks to their fire performance, energy efficiency, and decorative finish, these PU edge-sealed Rockwool metal siding panels are widely used in residential buildings, commercial facades, industrial facilities, modular houses, and renovation projects where safety, efficiency, and appearance are equally important.
