Glass Industry

Glass manufacturing is a high-temperature, energy-using industry. Glass making requires raw materials such as sand and recycled glass with a combination of refining, heating and casting processes. 

Industry and megatrends

The glass industry is subdivided into several sectors and each has its own specificity and manufacturing process. Generally, the glass sectors consist of three operations namely, the batch house, the hot end and the cold end. The batch house handles the raw materials while the hot end handles the manufacture via furnaces, annealing ovens, and forming machines. The cold end handles the product-inspection and packaging equipment. Generally, the glass melting process is the basis for all the glass sectors. It involves raw materials, energy and cutting-edge manufacturing installations.

Due to its low heat conductivity and brittleness, glass is not easy to process in industrial processes. The risk of breakage has to be minimized during production as well as for subsequent use due to tensions and micro-cracks caused during the production process. The moulds used in the glass industry required strong heat durability and high precision quality. The manufacturing of these moulds required expertise in forging, moulding and other secondary processes such as welding and thermal spray to enhance and repair the moulds.

Dura-Metal supported the industry with their specialised welding and thermal spray technologies. Our product range includes welding and coating equipment and consumables as well as product development on stainless steels, high-strength low-alloy and non-ferrous materials (copper, nickel, aluminum, titanium). In addition, Dura-Metal plays a vital role in joint development of parts for the various Glass industries’ applications.
