  2. Glass production - Wikipedia

    en.wikipedia.org/wiki/Glass_production

    Batch processing is one of the initial steps of the glass-making process. The batch house simply houses the raw materials in large silos (fed by truck or railcar), and holds anywhere from 1–5 days of material. Some batch systems include material processing such as raw material screening/sieve, drying, or pre-heating (i.e. cullet).

  3. Float glass - Wikipedia

    en.wikipedia.org/wiki/Float_glass

    Float glass. Float glass is a sheet of glass made by floating molten glass on a bed of molten metal of a low melting point, typically tin, [1] although lead was used for the process in the past. [2] This method gives the sheet uniform thickness and a very flat surface. [3] The float glass process is also known as the Pilkington process, named ...

    en.wikipedia.org/wiki/Fourcault_process

    The Fourcault process is a method of manufacturing plate glass. First developed in Belgium by Émile Fourcault [fr] (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 ...

    en.wikipedia.org/wiki/Precision_glass_moulding

    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. The tool system is nearly closed (no contact of the upper mould) and the entire system of mould, die and ...

    en.wikipedia.org/wiki/Flow_process_chart

    The first structured method for documenting process flow, e.g., in flow shop scheduling, the flow process chart, was introduced by Frank and Lillian Gilbreth to members of ASME in 1921 as the presentation "Process Charts, First Steps in Finding the One Best Way to Do Work". [2] The Gilbreths' tools quickly found their way into industrial ...

  7. Overflow downdraw method - Wikipedia

    en.wikipedia.org/wiki/Overflow_downdraw_method

    Overflow downdraw method. The overflow downdraw method or fusion method is a technique for producing flat glass. 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 ...
