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 ...
These are separated by a passage or a constriction (float glass). In the melting tank, the batch is melted and refined. The melt then passes through the passage into the working tank and from there into the feeder (forehearth). There the glass is removed. In hollow glass production (hollow glass), the glass machine below is fed with glass gobs.
Precision glass moulding is a replicative process that allows the production of high precision optical components from glass without grinding and polishing. The process is also known as ultra-precision glass pressing. It is used to manufacture precision glass lenses for consumer products such as digital cameras, and high-end products like ...
Only ten glass manufacturers are thought to have been operating in 1800. High-quality glassware was imported from England, and glassmaking knowledge was kept secret. England controlled a key ingredient for producing high–quality glassware and kept its price high—making it difficult for American glass manufacturers to compete price-wise.
Bucher Emhart Glass is a supplier of advanced technologies for manufacturing and inspection of glass containers. [49] [6] Their products include glass forming and inspection machines and spare parts, as well as consulting and service for the hollow glassware industry. [59] Production facilities are located in Sweden, [60] the United States and ...
A glass crusher provides for pulverization of glass to a yield size of 2 inches (5 cm) or less. [1] Recycling operations may range from simple, manually-fed, self-contained machines to extravagant crushing systems complete with screens, conveyors, crushers and separators. All non-glass contaminants must generally be removed from the glass prior ...
Machine drawn cylinder sheet was the first mechanical method for "drawing" window glass. Cylinders of glass 40 feet (12 m) high are drawn vertically from a circular tank. The glass is then annealed and cut into 7 to 10 foot (2 to 3 m) cylinders. These are cut lengthways, reheated, and flattened.
