Metals, in industries, like manufacturing, construction, aircraft and automotive play an important role. A highly ductile form of metal is needed by these sectors for manufacturing of numerous necessary units like cars, transport and other important units. For this reason, forging has become a crucial process in extrusion of metals.

Forging is a process which is done for forming or molding of metals. It is done through various techniques that are different for various metals and are used based on their temperature. Different lubricants are used for carrying out this process and commonest of them are MoS2, graphite, synthetics, and glass. Glass lubricants for forging process are used as they are very brittle even at higher temperatures. Therefore, because of this these glass lubricants are used in hot forging technique which is done at a temperature of 1300 degrees Celsius and is later reduced to 750 degrees Celsius.

Throughout this method, a forged glass coating is formed over metals which are water based and lead free. This glass coating is inculcated with high lubrication and heat insulation properties. So, they are used for forging of some particular alloys of metals like titanium, stainless steel, tungsten, and nickel. A few of the benefits that make this technique essential as a forging lubricant for aircraft industry are as follows:

- This technique prevents oxidization of metals that has undergone forged technique. So, it helps the structures prepared from these metals to remain in its initial shape and prevents their reaction with oxygen.

- This is an excellent lubricant as it takes the form of plastic at higher temperatures.

- Most significantly forged glass is the only lubricant that can bear so much high temperature without losing its scientific properties.

A common forging process used in aerospace industry is seamless ring rolling forging. In this technique a hole is punched in thick, piece of metal which creates its shape like a donut. After this these pieces are drawn under rolling and squeezing process into a ring. The diameter of ring varies according to the quantity of metal to be forged.

These seamless rings rollers can be either flat or cylindrical in shape. The height of those configurations differs between 0.5 inches to 9 feet. All this are dependent on the equipment used and according to it wall thickness and height are proportioned. The common ratio range is 1:16 at the base and 16:1 at the top, but this can vary in case of special processing's.

Forging method is crucial for increasing ductility and tangential strength of metals that make them suitable for parts that are resistant to pressure such as engines for aircrafts, couplings, gears, rotor pacers, cases and sealed discs, pressure vessels, wheel bearings, valve bodies and flanges.
