Manufacture of glass fibres

NACE v2.0 Code: C23.14

About 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 known for their exceptional strength, durability, and insulating properties, 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, including 22.21 Construction of residential and non-residential buildings, 29.32 Manufacture of other parts and accessories for motor vehicles, and 31.09 Manufacture of other furniture.

Production process

The manufacture of glass fibres typically involves a multi-step process. First, raw materials such as sand, limestone, and other minerals are melted in a furnace at high temperatures, typically around 1,400°C. The molten glass is then extruded through small orifices, forming fine 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 application.

Production inputs

The primary inputs for the manufacture of glass fibres include high-purity silica sand, limestone, soda ash, and other mineral additives. Specialized equipment, such as glass-melting furnaces, fibre-forming equipment, and winding machines, are also essential for the production process. Additionally, the industry relies on a skilled workforce capable of operating and maintaining this complex machinery.

Production outputs

The primary output of the glass fibre manufacturing industry is a range of glass fibre products, including continuous filament glass fibres, chopped glass fibres, and glass fibre mats or fabrics. These materials are widely used as reinforcements in 22.21 Construction of residential and non-residential buildings, 29.32 Manufacture of other parts and accessories for motor vehicles, and 31.09 Manufacture of other furniture. Glass fibres are also used in the production of insulation materials, specialty textiles, and various composite materials.
