The production process of handcrafted rock wool boards primarily includes steps such as batching, melting, blowing, laying, pressing, cutting, and packaging.

Ingredients: According to product requirements, various raw materials are mixed in specific proportions to form the raw material for rock wool boards. These materials typically include natural rocks such as basalt and diorite, as well as possible additives like flux and binder.

Melting: The mixed raw materials are placed into a high-temperature melting furnace and heated until they reach a molten state. The furnace temperature typically exceeds 1450 degrees Celsius to ensure the raw materials are fully melted and form a uniform magma.

Blow Spinning: Molten raw materials are ejected through specific nozzles to form fine fibers. These fibers are subjected to centrifugal force during the blowing process, gradually taking on a certain shape of rock wool fibers. The blowing process requires controlling parameters such as nozzle diameter, blowing speed, and pressure to achieve ideal fiber shape and distribution.

Fiberglass Laying: The blown fibers are laid onto the substrate to form the preliminary shape of rock wool boards. The laying process must ensure even distribution and tight arrangement of the fibers to enhance the thermal insulation and strength of the rock wool boards.

Compression: The fiber mat is compressed into rock wool boards of specific thickness and strength through high temperature and pressure methods. The compression process requires the control of parameters such as pressure and temperature to achieve ideal board performance and appearance.

Cutting: The compressed rock wool boards are cut to specified dimensions to form standardized products. The cutting process must ensure the dimensional accuracy and edge quality of the boards to meet customers' customization requirements.

Packaging: Cut rock wool boards are packaged for easy transportation and storage. The packaging materials are typically selected for their moisture-proof, dust-proof, and corrosion-resistant properties to ensure the boards remain undamaged during shipping and storage.
