Manufacture of glass fibres

NACE code 23.14 covers the manufacture of glass fibres, a critical component in a wide range of industries. Glass fibres are renowned for their exceptional strength, durability, and versatility, making them indispensable in applications such as reinforced plastics, insulation materials, and specialty textiles. This industry plays a vital role in supporting the growth and development of various sectors, from construction and transportation to electronics and renewable energy.

The manufacture of glass fibres typically involves a multi-step process. First, raw materials such as sand, limestone, and other minerals are melted at high temperatures in a furnace. The molten glass is then extruded through small orifices, forming continuous filaments. These filaments are then cooled, coated with a protective sizing, and either wound onto spools or chopped into shorter lengths, depending on the desired product. Advanced techniques, such as the use of advanced control systems and precision equipment, ensure consistent quality and efficiency in the production process.

The primary inputs for the glass fibre manufacturing industry include high-purity silica sand, limestone, and other mineral raw materials. Specialized equipment, such as furnaces, extruders, and winding machines, are also essential for the production process. Additionally, the industry relies on energy sources, such as natural gas or electricity, to power the high-temperature melting and extrusion operations.

The primary output of the glass fibre manufacturing industry is a range of glass fibre products, including continuous filaments, chopped strands, and mats. These outputs are then consumed by various other industries, such as 22.21 Manufacture of plastic plates, sheets, tubes and profiles, 23.11 Manufacture of flat glass, and 29.32 Manufacture of other parts and accessories for motor vehicles. Glass fibres are widely used as reinforcement materials in composite products, as well as in insulation and filtration applications.
