In the process of hot forging dilute water based lubricants are used to spray on hot surfaces of die to cool it down and for lubrication
purpose. The dilution ratio is decided by considering the parameters such as, die temperature, type of material being forged, forging
temperature, structure complexity of die. Lubricity and adhesion are also very important properties to be considered. If dilution is
very less lubricant itself offers more frictional force and problem of less cooling takes place and if dilution is very high than
expected then more water droplets may cause problem in adhesion property. So dilution plays an vital role in quality lubrication and
quality forging. Manual process of dilution introduces more errors so it reduces standard of lubrication. Electronic components such
as sensors, solenoid valves helps to increase accuracy with using automation tools.
