Open Die Forging

Open Die Forging Solutions for Large Industrial Components

FWD Forgings provides customized Open Die Forging solutions for customers requiring large-scale forged components with excellent structural integrity, flexible dimensions, and reliable performance for heavy industrial applications.

Open die forging uses repeated pressing between flat or simple-shaped dies to gradually shape heated metal. Unlike closed die processes that depend on fixed cavities, this method provides greater flexibility for manufacturing oversized components, large cross-sections, and engineering forgings with customized dimensions.

As a professional steel forging manufacturer, FWD supplies large forged components for energy equipment, heavy machinery, industrial systems, and other applications requiring robust forged structures.

Manufacturing Advantages of Large-Scale Forging

Manufacturing Capability for Oversized Forgings

Open die forging is particularly suitable for components that exceed the size limitations of enclosed dies.

Typical components include:

• Large shafts
• Heavy discs
• Forged rings
• Large round bars

Improved Internal Material Structure

During open die forging, repeated deformation helps refine the internal grain structure and improve material consistency throughout large sections.

Benefits include:

• Better structural uniformity
• Improved reliability
• Enhanced service performance

Flexible Dimensions Without Fixed Die Cavities

Because the process does not rely on complex permanent dies, open die forging allows greater flexibility in:

• Component diameter
• Length
• Weight
• Final geometry

This makes it suitable for customized engineering projects and special-size forgings.
