· High-pressure air blowing technology.

The resulting fibers have uniform diameter and excellent insulation properties.

■ Forming Process

The fibers are evenly distributed through a forming machine or vacuum forming system to create the initial insulation mat.

■ Thermal Curing and Shaping

An inorganic binder is applied to the fiber surface.

The material then passes through a drying furnace or curing furnace for high-temperature treatment, forming stable rock wool boards, rolls, or other insulation products.

■ Cutting and Packaging

After shaping, rock wool products are cut according to customers’ requirements.

Finished products are packed in:

· Bags;

· Cartons;

· Pallets.

This ensures safe transportation and convenient storage.
