Custom Open Die Forging Capabilities

Custom Open Die Forging Manufacturing Capabilities

The open die forging process consists of contorting a piece of metal between 2 separate dies. The metal is then manipulated through die pressing the material through a series of movements until the desired shape is achieved.

The metal products created through the custom open die forging process usually need secondary machining and refining to achieve the tolerances required for the finished specifications. Open die forgings are often used for parts that are basic, rather than advanced, in design, such as discs, rounds, sleeves, cylinders and shafts.

Custom Forged Metal Parts

Custom forged metal shapes can also be produced through the open die forging process. The deformation process increases the strength of the grain structure, which creates a more stabilized custom open die forging. Some additional benefits include improved fatigue resistance, strength and also reduces voids.

Custom Forged Metal Parts

Blocks, Rectangles & Flats

Forged blocks, rectangles, and flats provide greater strength over standard plate or bar steel are valued for the enhancements they lend parts for performance in high-pressure environments, applications in which corrosion resistance is important.


Forged flats provide superior mechanical qualities over standard plate or rolled bar products. Forged flats can also be easily forged with a minimum thickness of 2.5” and in sizes up to 24” wide and 144” long.

Rounds, Discs & Sleeves

These shapes are produced utilizing our state-of-the-art custom computer software which increases accuracy, ease of replication, and speed of production time, thus saving you money on your part.

Hubs, Spindles & Stepshafts

Forged hubs, spindles, and stepshafts provide greater strength and fatigue resistance with continuous grain flow.

Steel Shafts

As a premier forged shaft manufacturer Great Lakes Forge can produce forged steel shafts weighing up to 4,000 lbs. Our stainless steel forging lead times are the best in the industry, often 2 times faster than our larger competitors. 

Stainless Steel Blocks

We can manufacture high-pressure forged stainless steel blocks that provide excellent corrosion resistance and a finish that’s perfect for several different types of applications.

Stainless Steel Fluid Ends

Our forged fluid ends set the standard for strength, consistency, and quality. Forged fluid ends provide improved microstructure, continuous grain flow, and higher fatigue resistance.
