Fully Automatic PU Shutter Door Metal Sheet Shutter Door Roll Forming Machine

PU roller shutter doors are designed for efficient and secure protection in various settings, offering excellent thermal insulation and noise reduction due to their polyurethane foam core. These doors provide enhanced security, durability, and energy efficiency, making them ideal for commercial, industrial, and residential applications.

PU roller shutter doors are commonly used for warehouses, garages, and loading docks in commercial and industrial environments to ensure security and maintain internal temperatures. They are perfect for garages and storage areas in residential settings, providing a robust barrier against external elements while enhancing the property's energy efficiency. Their noise reduction properties are also suitable for areas requiring minimal sound disturbance. These doors are versatile, easy to operate, and require low maintenance, making them a practical and cost-effective solution for many applications.

Foam Casting Machine&Heated House

The injection molding machine plays a crucial role in the production process by mixing PU raw materials, heating them, and injecting the mixture into the steel panels. This process ensures that the PU foam is properly filled into the steel panels. After injection, the materials undergo a chemical reaction due to the applied heat, filling the steel panels.

The heated house enhances the bonding between the polyurethane and the steel panels. After the PU foam is injected and undergoes initial foaming, the heating room provides the necessary conditions for curing and drying. This process stabilizes the molecular structure of the PU foam, ensuring a strong and durable adhesion to the steel panels. The heating room thus plays a vital role in ensuring the quality and stability of the final product.

Straightening Device

The straightening device is primarily used to correct product bends. It corrects arch bends through the first three straightening passes, while side bends are adjusted using the straightening head. This ensures the final product is straight and meets the required specifications.

Packaging and Shipping

1. Anti-corrosion oil is sprayed during transportation to prevent oxidation of the machine

2. Packaging isolation film to prevent machine oxidation during transportation

3. Fixed on the container with wire to prevent damage to the machine during transportation
