About clock or watch glasses and similar glasses; glasses for spectacles, not optically worked; hollow glass spheres and their segments for the manufacture of such glasses
cpc code 37194 covers a diverse range of glass products that are essential components in the manufacturing of clocks, watches, and spectacles. These specialized glass items play a crucial role in the broader optical and timekeeping industries, contributing to the functionality and aesthetics of a wide array of consumer and industrial products. As a key supplier to these downstream sectors, the 37194 industry is an important part of the overall economy, enabling the production of everyday items that many people rely on.
Production process
The production of the glass products covered under cpc code 37194 typically involves a combination of glass blowing, molding, and precision cutting techniques. Manufacturers begin by melting raw materials such as silica, soda ash, and limestone to create the desired glass composition. The molten glass is then shaped into the required forms, whether it's clock or watch glasses, spectacle lenses, or hollow glass spheres. Advanced techniques like precision grinding and polishing may be employed to ensure the final products meet stringent optical and dimensional specifications.
Production inputs
The main inputs required for the 37194 industry include high-quality raw materials like silica, soda ash, and limestone, as well as specialized machinery for glass melting, shaping, and finishing. Manufacturers in this sector also rely on skilled labor to operate the production equipment and ensure consistent quality. Additionally, access to reliable energy sources and transportation infrastructure are crucial for the efficient operation of 37194 facilities.
Production outputs
The primary outputs of the 37194 industry are the various glass components used in the manufacture of clocks, watches, and spectacles. These include clock and watch glasses, spectacle lenses, and hollow glass spheres that are used as the base material for producing such optical components. The outputs of this industry are then consumed by 38111 Manufacture of watches and clocks, 38112 Manufacture of spectacles and lenses, and other related industries that incorporate these specialized glass products into their final products.
