Maximize Efficiency with Our Advanced PU Sandwich Panel Rolling Forming Machine
Looking to improve your insulated panel production? Our PU sandwich panel rolling forming machine offers a comprehensive solution for manufacturing high-quality polyurethane sandwich panels with precision and speed. Equipped with advanced components including a metal decoiler, embossing system, high-efficiency PU foaming unit, integrated heating mechanism, and automated shearing system, this machine is built to meet the evolving demands of the modern construction and insulation industries.
I. What Is a PU Sandwich Panel Rolling Forming Machine?
A PU sandwich panel rolling forming machine is a highly specialized piece of equipment designed to manufacture polyurethane (PU) insulated panels. These panels are widely used in cold storage facilities, industrial buildings, clean rooms, and other structures requiring thermal insulation, fire resistance, and structural strength.
The machine automates the entire panel production process — from feeding raw metal coils to foaming, forming, heating, and final cutting. The result is a consistent, high-quality sandwich panel that meets international standards.
II. Core Components and Functional Features
Our system integrates a range of high-performance units that work in tandem to produce flawless PU panels.
1. Metal Decoiler (Hydraulic or Manual Options)
Start your production with a choice of manual or hydraulic decoilers, designed to support various coil weights and widths. The hydraulic version enables automatic coil expansion and rotation, improving operator safety and boosting efficiency. The manual type is ideal for budget-conscious operations or small production batches.
Coil width: 1000mm–1250mm
Coil weight capacity: Up to 5 tons
Inner diameter: 508mm–610mm
2. Embossing Machine (Custom Pattern Options)
Before foaming and forming, the metal surface can be enhanced with patterns using our adjustable embossing machine. You can choose from a variety of embossing styles — diamond, brick, stucco, or customized designs — depending on aesthetic or functional needs.
Adjustable pressure and depth
Temperature-controlled rollers for uniform effect
Surface hardening for longer roller lifespan
3. PU Foaming & Rolling System (Core of the Machine)
The PU foaming machine is at the heart of the entire line, precisely injecting polyurethane foam between two layers of metal sheets. The dosing unit ensures the correct ratio of isocyanate and polyol, while the continuous foaming conveyor maintains panel consistency.
High-pressure mixing head for even PU distribution
Conveyor width: 1000–1200mm
Foam density: Adjustable (30–50kg/m³)
CE-certified components
The integrated roll forming station shapes the upper and lower metal sheets, guaranteeing perfect bonding with the PU core.
III. Heating and Thermal Bonding System
To ensure proper adhesion and activation of polyurethane, the machine includes a controlled heating system. This module maintains optimal temperature throughout the foaming and pressing processes.
Digital temperature control
Infrared or oil-heated elements (customizable)
Uniform heating surface to prevent foam deformation
The heating system ensures fast curing and strong bonding of the PU core with the steel surface, critical for product strength and long-term performance.
IV. Precision Shearing System
At the final stage, the completed sandwich panels are automatically cut to length by a servo-driven shearing system. This cutting mechanism ensures clean, accurate panel edges and supports programmable length settings for flexible production.
Cutting tolerance: ±1mm
Max cutting length: 12m
Blade material: Hardened high-speed steel
Noise-reduction hydraulic control
