Hot precision forging technology is defined as a near net-shape forging operation which generates high-quali-ty parts concerning surface quality and dimensional accuracy. The mechanical properties of forgings are improved by hot precision forging. Precision forging is a highly efficient green manufacturing technology which eliminates or reduces genera-tion of waste, and saves raw material and cost. The paper introduced the current application status of hot precision forging technology, reviewed the current worldwide research status of hot-die forging, isothermal forging, design optimization of preformed forgings and process optimization of precision forging, and finally prospected the development tendencies of hot precision forging technology.
