Introduction to Cold Forging

by Bradley Dodd

Cold forging is a common industrial process in which metal workpieces are plastically shaped by suitably contoured dies to form a final desired shape. The process itself is a predominantly compressive one in which the workpiece is squeezed between the dies.

Cold forging is an important process being used in many industries, for example the automotive industry in which a huge annual tonnage of cold forged components are used.

Important aspects in cold forging are: the die material and shape, the lubricant, the workpiece material, and the temperature.

Cold forging is generally understood to mean forging at room temperature or a temperature at which no microstructural changes occur as a result of the process. Warm forging is now gaining in popularity because ambient temperatures are elevated a little to decrease the required loads whilst maintaining good tolerances for the products.

Numerical analyses and simulations are now used commonly in the cold forging industry to optimize the processes and to decrease overall costs. For example in multi-step processes the number and nature of each step are very important in the cost of the finished component.

It is the objective of the ICFG to further the use of cold forging, therefore the organization is concerned with all the above variables as well as numerical analyses and simulations.
