Process of Manufacturing PUF Sandwich Panels at VIRAAT INDUSTRIES

Manufacturing PUF Sandwich Panels is a fascinating process that involves multiple steps and considerations. These panels, known for their excellent insulation properties and structural strength, have become widely used in industries ranging from construction to automotive.


Preparing the Raw Materials

The first step in the manufacturing process of PUF Sandwich Panels at Viraat Industries involves preparing the raw materials needed to form the core and the facings. This includes carefully measuring and mixing polyols and isocyanates to create the polyurethane foam. Additionally, the chosen facing materials must be cut and shaped according to the required dimensions.


Bonding the Facings to the Core

Once the raw materials are prepared, the facings are bonded to the polyurethane foam core. This is achieved by using a combination of adhesives and heat. The adhesive is carefully applied to the facings, ensuring even coverage. Then, the facings are firmly pressed onto the foam core, creating a strong bond. Heat is often applied during this process to accelerate the curing of the adhesive and ensure a secure connection.


Forming and Cutting the Panels

After the facings are bonded to the core, the PUF Sandwich Panel is formed and shaped according to the desired dimensions. This can be achieved through a variety of methods, including compression molding or continuous panel production lines. Once the PUF Sandwich Panels are formed, they are cut to the required sizes using specialized cutting equipment. This step ensures uniformity and precision in the final product.


Post-Production Finishing

To enhance the quality and durability of the PUF sandwich panels, various post-production finishing processes are undertaken at Viraat Industries Manufacturing Units in Hosur, Tamil Nadu. These may include surface treatments, such as applying protective coatings or laminates, to improve resistance to weathering and corrosion. Additionally, PUF Sandwich Panels can be customized with embossed patterns or textures to suit specific aesthetic requirements.


Quality Assurance and Testing

Ensuring the quality and performance of PUF Sandwich Panels is of utmost importance for Viraat Industries thus making Viraat Industries India’s #1 PUF Sandwich Panel. Viraat Industries employ rigorous testing procedures to guarantee that the panels meet or exceed industry standards.
