CPC v2.1 Code: 37112

About unworked cast, rolled, drawn or blown glass, in sheets

cpc code 37112 covers the production of unworked cast, rolled, drawn or blown glass in sheet form. This industry plays a crucial role in the broader glass manufacturing sector, supplying essential raw materials for a wide range of downstream applications across various industries. The production of these glass sheets is a fundamental step in the glass supply chain, enabling the creation of finished glass products that are integral to modern life.

Production process

The main production techniques used in this industry involve casting, rolling, drawing, or blowing the glass to create thin, flat sheets. These processes typically start with the melting of raw materials such as sand, soda ash, and limestone in a furnace. The molten glass is then carefully controlled and shaped using specialized equipment to produce the desired sheet-like form. The sheets may undergo additional processing, such as annealing or tempering, to enhance their strength and durability.

Production inputs

The primary inputs required for the production of unworked cast, rolled, drawn or blown glass sheets include raw materials like silica sand, soda ash, and limestone. Additionally, the industry relies on specialized machinery and equipment, such as furnaces, rollers, and drawing or blowing mechanisms, to facilitate the manufacturing process. Energy sources, such as natural gas or electricity, are also crucial inputs for the melting and shaping of the glass.

Production outputs

The main outputs of this industry are the unworked glass sheets, which are then consumed by various downstream industries. These sheets may be further processed, coated, or laminated to create a wide range of glass products, including 37121 Float glass, 37122 Safety glass, and 37123 Glass mirrors. The glass sheets produced under cpc code 37112 are essential inputs for the construction, automotive, and electronics industries, among others.
