Automatic Continuous Sandwich Panel Production Line for EPS/Rock Wool/PU

Automatic Continuous Sandwich Panel Production Line for EPS/Rock Wool/PU：

The XINNUO Standard in Sandwich Panel Technology

In the modern construction and industrial warehousing sectors, the demand for high-performance, insulated, and fire-resistant building materials is surging. Hebei Xinnuo Roll Forming Machinery, as a global leader in cold roll forming technology, presents its flagship Automatic Continuous Sandwich Panel Production Line. This 65-meter industrial powerhouse (S-type configuration) is engineered to transform raw steel coils and insulation cores into premium structural insulated panels (SIPs) with unmatched precision and speed.

Comprehensive Integrated Engineering Unlike standard single-layer roll formers, a sandwich panel machine is a highly complex multi-stage engineering system. The XINNUO line integrates two independent forming units (for upper and lower steel skins), a precision glue injection system, a specialized core material feeding unit (compatible with EPS, Rock Wool, and Glass Wool), and a heavy-duty lamination zone. This integration ensures that the composite bonding process—where the steel skins meet the insulation core—is seamless, preventing air bubbles and delamination.

Unmatched Lamination Precision The "heart" of the Xinnuo composite machine lies in its lamination and pressing section. While industry standards typically use 32 to 40 rubber rollers, Xinnuo utilizes 54 high-density rubber rollers (胶轴). This extended contact zone provides a longer curing time under pressure, ensuring a significantly stronger bond between the core material and the steel sheets. The 12-meter roller bed is CNC-machined to a flatness tolerance of 0.05mm, guaranteeing that every panel produced meets the strictest architectural flatness standards.

Versatility Across Insulation Cores Global markets have varying building codes. Xinnuo’s production line is designed for modular compatibility. Whether your project requires lightweight EPS (Expanded Polystyrene) for cost-effective insulation, high-efficiency PU (Polyurethane) for cold storage, or A-grade fire-rated Rock Wool for high-risk industrial zones, our machine adapts effortlessly. The rock wool feeding unit is specifically reinforced to handle the weight and abrasive nature of mineral fibers without compromising line speed.

Structural Rigidity and Durability Built on a heavy-duty 350H industrial steel frame, the entire line is designed for 24/7 continuous operation. Every roller and shaft is manufactured from high-quality 45# steel, heat-treated and hard-chrome plated to resist wear and corrosion. The PLC control system, powered by industry leaders like Delta or Siemens, allows operators to adjust panel length, production speed, and glue flow rates from a single, intuitive interface.

Trust and Global Reach Choosing Xinnuo means investing in a legacy of industrial authority. We provide comprehensive after-sales support, including S-type factory layout planning, remote technical assistance, and on-site commissioning. Our machines are currently serving large-scale infrastructure projects in over 30 countries, reinforcing the XINNUO standard of durability and technological superiority.
