The role of the cold end of glass container production is to complete the final tasks in the manufacturing process: spray on a polyethylene coating for abrasion resistance and increased lubricity, inspect the containers for defects, label the containers, and package the containers for shipment.
The Fourcault process is a method of manufacturing plate glass. First developed in Belgium by Émile Fourcault (1862–1919) during the early 1900s, the process was used globally. Fourcault is an example of a "vertical draw" process, in that the glass is drawn against gravity in an upward direction. [1] Gravity forces influence parts of the ...
The float glass process is also known as the Pilkington process, named after the British glass manufacturer Pilkington, [4] which pioneered the technique in the 1950s at their production site in St Helens, Merseyside. [5] Modern windows are usually made from float glass, [6] though Corning Incorporated uses the overflow downdraw method. [7]
Until the 20th century, window glass production involved blowing a cylinder and flattening it. [9] Two major methods to make window glass, the crown method and the cylinder method, were used until the process was changed much later in the 1920s. [10] All glass products must then be cooled gradually , or else they could easily break. [11]

Summary of process Temperature (in °C), travel (in mm), and force (in N) during the process. The precision glass moulding process consists of six steps: [1] [2] The glass blank is loaded into the lower side of the moulding tool. Oxygen is removed from the working area by filling with nitrogen and/or evacuation of the process chamber.
Glass casting is the process in which glass objects are cast by directing molten glass into a mould where it solidifies. The technique has been used since the 15th century BCE in both Ancient Egypt and Mesopotamia. Modern cast glass is formed by a variety of processes such as kiln casting or casting into sand, graphite or metal moulds.
The manufacturing process for soda–lime glass consists in melting the raw materials, which are the silica, soda (Na 2 O), hydrated lime (Ca(OH) 2), dolomite (CaMg(CO 3) 2, which provides the magnesium oxide), and aluminium oxide; along with small quantities of fining agents (e.g., sodium sulfate (Na 2 SO 4), sodium chloride (NaCl), etc.) in a glass furnace at temperatures locally up to 1675 ...
