Metal Forming: Forgings – Closed Die Processes

Forgings: Closed Die Processes introduces learners to the pre-forging processes, conventional forging, and final inspection. The important and commercially vital process of closed die forging is brought to life in this course using realistic 3D models, helpful animations, and interactive quizzes. The material in this course is beneficial for both experienced forging veterans and learners new to the industry.

Learning Objectives

  • Recall some of the primary products created by forging processes.
  • Recognize the basic equipment used in forging processes.
  • Understand some common terms such as billet, blank, press, and die.
  • Recall some of the basic forging design considerations.
  • Distinguish between the various steps in the forging process.
  • Recognize some of the post-forging processes, such as heat treatment and testing.
