Open Die "Hand" Forgings

Stress relieving on 8000-ton press

Open Die Forgings, also known as "Hand Forgings" or "Forged Block," are manufactured in flat dies, eliminating the requirement for nonrecurring tooling. They are characterized by specific grain directions (ST - Short Traverse; LT - Long Traverse; and L - Longitudinal), and are produced in many shapes, from the classic "block" configurations to bent, stepped, or curved shapes.

Preparing for stress relief

Reasons to choose Open Die Forgings include:

Cost of developing closed die forging tool is prohibitive.
Engineering of the component is not yet finalized and creating the closed die tooling is premature.
The part requires forged properties and machining an open die forging is the most economical method to achieve your goal.
The lead time for developing closed die tooling may not support your program.
