Types of Die Forgings
Die forgings are generally classified as blocker-type, finish only, conventional, and precision. Blocker-type forgings are designed with large fillets and corner radii, thick webs, and ribs. This is so that the forgings can be produced in a set of finished dies only. Producing blocker-type forgings typically entails a unit pressure of 10 to 15 tons per square inch of projected plan area depending on the alloy and complexity of the design.
Finish only forgings pass the forged part through the press more than once to form the starting stock to the required configuration. Finish only forgings are best for low quantities or prototypes due to the amount of passes and wear that is caused to the die.
Conventional forgings are the most common of the die forging types. Conventional forgings require a unit pressure of 15 to 25 tons per square inch of projected plan area.
Precision forgings can be identified by the near-net tolerances. Highly intricate forging designs that have corner radii, draft angles, and small fillet radii should be considered for precision forging production. The cost of precision forging is higher than other die forging practices. However, design configurations can include close tolerances, greater detail, weight variations, and little to no machining. Where the justification would lie is in the removal of the machining costs and production quantity. Precision forgings require a unit pressure of 20 to 30 tons per square inch of projected plan area.

The Advantages of Precision Aluminum Forging
Precision forging was developed during WWII when the U.S. Department of Defense was in need of mass producing airplane and rotor craft parts to support the war. As the commercial airline industry developed, precision forging became of even greater importance. With advances in machining practices, precision forging is now less used as a solution in the production of aluminum parts. There are, however, major advantages of using precision forging for certain parts over any other production practice. Here are some thoughts to consider when planning your next project.
Does your part contain complex contoured surfaces with various orientations?
Precision forging, once established, can consistently forge a part providing excellent surface quality and dimensional integrity.
Will your part need to withstand high internal pressures from an air or a liquid source?
The grain flow produced in precision forgings can eliminate the concern of corrosion or mechanical property failure due to air or water pressure.
