Broadly, modern glass container factories are three-part operations: the "batch house", the "hot end", and the "cold end". The batch house handles the raw materials; the hot end handles the manufacture proper—the forehearth, forming machines, and annealing ovens; and the cold end handles the product-inspection and packaging equipment.
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]
The company's F. C. Ball machine, patented in 1898, introduced mass production into its glass-blowing process and gave it a competitive market advantage. By 1905 the company was producing 60 million canning jars per year and had acquired other glass manufacturers, expanding its operations to include seven factories in addition to its main ...
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]
The company had been producing glass using Fourcault process which is costlier than the Float glass process used by private manufacturers in Bangladesh. The company had to sell their products at below manufacturing costs and had been making a loss for the last 5 years.
The key advantage of this technique as compared to the float glass process is that the pristine surfaces are not touched by molten tin. The technique is used for the production of very thin flat panel display glass by the companies Asahi Glass Co. , Corning , Nippon Electric Glass , [ 1 ] Samsung Corning Precision Materials , and various other ...
In manufacturing, glass-ceramics are valued for having the strength of ceramic but the hermetic sealing properties of glass. Glass-ceramics are mostly produced in two steps: First, a glass is formed by a glass-manufacturing process, after which the glass is cooled down. Second, the glass is put through a controlled heat treatment schedule.
