Die lubrication is key for quality and productivity in hot forging processes. The right lubricant must reduce friction to allow smooth metal flow while also releasing, cooling, and protecting the die to extend its life. Proper lubricant selection and application parameters are important. Forging lubricants typically contain graphite, which helps lubricate and release the forged part from the die. Maintaining consistent lubricant concentration and application are important for optimizing the forging process.
