Polyurethane Roof Sandwich Panel Machine

The polyurethane roof sandwich panel machine is the core equipment for the production of modern building thermal insulation materials. Through the automated continuous production line, the color coated steel plate and polyurethane foam are compounded to produce building panels with both structural strength and excellent thermal insulation performance.

The polyurethane sandwich panel machine integrates mechanical engineering, materials science, and automation control technology, and can efficiently produce roofing materials widely used in industrial plants, cold chain logistics, sports venues, and other buildings.

The production machines for polyurethane roof sandwich panels are mainly divided into two categories: continuous and intermittent, each adapted to different production needs.

Continuous polyurethane roof sandwich panel production line

• Production feature: Can achieve 24-hour uninterrupted production
  

• Typical configuration: Double roll system → Steel plate cleaning/pretreatment → Automatic correction → Molding unit → Preheating system → Foam injection → Double track laminating → Hot air curing → Automatic trimming → Fixed length cutting → Finished product stacking
  

• Advantages: High production efficiency, unlimited board length, excellent product consistency

Intermittent laminating equipment

• Production characteristics: Suitable for small batch customized production
  

• Workflow: Manual laying of bottom steel plate → placement of frame → pouring of foam → covering of top plate → hydraulic pressing → hot air curing → demolding
  

• Advantages: Low equipment investment, flexible mold replacement for producing special-shaped plates
  

• Special application: Production of cold storage panels with convex groove structures

The polyurethane sandwich panel production line consists of multiple precision matched subsystems, each of which undertakes critical functions.

The finished products produced by mechanical equipment for polyurethane roof sandwich panels are widely used in:

• Industrial construction field
  Steel structure factory roof
  Logistics warehousing center

• Cold chain infrastructure
  Cold storage roof system
  Food processing workshop

• Public Buildings
  airport terminal
  sports venue
