PU/PIR/Rockwool Sandwich Panel Production Equipment

PU/PIR/Rockwool Sandwich Panel Production Equipment

Sinowa is a manufacturer of sandwich panel production equipment in china, sandwich panel equipment is integrated and modular special equipment for building materials. It combines color steel/aluminum face sheets with rock wool, mineral wool, PU, PIR and glass wool core materials through cold forming, gluing and pressure curing. The whole line supports full automatic continuous production from raw material feeding to finished panel stacking. Ideal for producing insulated, fireproof, soundproof and load-bearing sandwich panels, widely applied in building enclosure, industrial purification and cold chain warehousing. It is the core equipment for modern prefabricated construction materials.

Continuous Sandwich Panel Equipment

An all-in-one automatic sandwich panel equipment for continuous production of rock wool, PU, PIR and pf insulation sandwich panels. Covering unwinding to palletizing, it is ideal for manufacturing insulated wall & roof panels used in factories, coldrooms and cleanrooms.

Classification of Sandwich Panel Production Equipment

Sandwich panel equipments are classified by production process, core material and automation level. Main types are listed below:

Core Structure & Functions of Sandwich Panel Equipment

Polyurethane Sandwich Panel Production Equipment

This modern sandwich panel line adopts modular design. Each unit works independently and cooperates efficiently. It features compact layout and stable performance.

  1. Uncoiling & Leveling System
    Equipped with double-shaft uncoiler and correction device. It flattens metal coils, removes bends and keeps sheets straight for the next production process.
  2. Cold Roll Forming System
    Made of precision rollers and servo motors. It shapes metal sheets into various profiles, such as corrugated and lap shapes. No deformation during forming.
  3. Gluing & Laminating System
    Automatic glue control for different core materials. Organic core uses foam injection; inorganic core uses double-sided gluing. Strong bonding without delamination.
  4. Hot Press Curing System
    Constant temperature and constant pressure design. It fastens glue curing, keeps panels flat and improves overall structural strength.
  5. Fixed-length Cutting System
    Servo tracking cutting realizes non-stop production. Clean burr-free cutting edge. Custom panel length is available.
  6. Conveying & Stacking System
    Automatic conveying, stacking and packing. Reduce manual labor. Keep finished panels neat for easy storage and delivery.
  7. Intelligent Control System
    PLC+touch screen control. One-click parameter switching. Real-time monitoring of temperature, pressure and speed. Simple operation and intelligent management.

General Working Process of Sandwich Panel Making Equipment

PU Sandwich Panel Production Equipment

Continuous sandwich panel machinery adopts standardized workflow:

  1. Raw Material Feeding
    Mount metal coils on uncoiler and prepare core materials.
  2. Leveling & Forming
    Metal sheets are uncoiled, leveled and formed into required profiles.
  3. Gluing & Core Laying
    Even adhesive spraying and accurate core material placement.
  4. Hot Press Bonding
    Thermal compression under constant temperature for firm lamination.
  5. Fixed-length Cutting
    Automatic precision cutting according to customized length.
  6. Stacking & Discharging
    Finished panels are stacked, packed and stored.

Core Technical Advantages of Sandwich Panel Manufacturing Equipment

PIR Sandwich Panel Production Equipment
  1. High Efficiency
    Sandwich panel continuous production line with seamless workflow. Capacity increases by over 30% compared with intermittent machines. Less manual operation, perfect for mass production.
  2. High Flexibility
    Modular design supports quick switching of plate thickness, shapes and core materials. Compatible with rock wool, PU, glass wool for diversified production.
  3. High Precision
    Servo drive and automatic correction ensure precise processing. Plate tolerance is controlled within ±0.5mm for smooth surface and stable bonding.
  4. Stable & Durable
    Thickened steel frame for long continuous operation. Premium electric parts reduce failure rate and maintenance cost.
  5. Eco & Energy Saving
    Frequency conversion system saves power. Eco-friendly raw materials generate no redundant waste, meeting industrial environmental standards.
