Warm Forging
The warm forging manufacturing process occurs within the temperature range of 650 °C and 1000 °C, depending on the used material and the components type. This is usually above the work hardening temperature of the workpiece and below the temperature at which scale forms. Warm Forged Common Rails If the forging temperature is below the transformation point of 740-770 °C, the material should undergo a preliminary heat treatment. This temperature range is used for parts with medium complexity which don’t require heat treatment after forging. For parts with greater complexity, the forging temperature is above the transformation point. Although this temperature range is close to the one of hot forging, in terms of technology warm forging is rather similar to cold forging. The warm forging process is placed somewhere between the cold and hot forging techniques, combining all their advantages as surface quality, precision, material usage and flexible shapes but generally requires high engineering skills (tools design, cooling, lubrification) and a dedicated forging press.

Cold Forging
Cold Forging Cold forging deforms metal while it is below its recrystallization point. Cold forging is generally preferred when the metal is already a soft metal, like aluminum. This process is usually less expensive than hot forging and the end product requires little, if any, finishing work. Sometimes, when aluminum is cold forged into a desired shape, it is heat treated to strengthen the piece. This is called “tempering.” The Cold Forging Process Despite the word “cold,” cold forging actually occurs at or near room temperature. The most common metals in cold forging applications are usually standard or carbon alloy steels. One of the most common types of cold forging is a process called impression-die forging, where the metal is placed into a die that is attached to an anvil. The metal is then hit by a descending hammer and forced into the die. Depending on the product, the hammer may actually be dropped on the metal numerous times in a very rapid sequence. Cold Forging Considerations Manufacturers may choose cold forging over hot forging for a number of reasons—since cold forged parts require very little or no finishing work, that step of the fabrication process is often dispensable, which saves money. Cold forging is also less susceptible to contamination problems, and the final component features a better overall surface finish. Other benefits of cold forging include: Easier to impart directional properties Improved interchangeability Improved reproducibility Increased dimensional control Handles high stress and high die loads Produces net shape or near-net shape parts Some possible disadvantages include: Easier to impart directional properties Improved interchangeability Improved reproducibility Increased dimensional control Handles high stress and high die loads Produces net shape or near-net shape parts The metal surfaces must be clean and free of scale before forging occurs The metal is less ductile Residual stress may occur Heavier and more powerful equipment is needed Stronger tooling is required This atricle from Thomasnet.com
