Closed die forging is one of the forging methods that produces a desired part in which dies move towards each other and covers the piece in whole or in part.
Closed die forging process begins with heated round bars, which is cut to the shape or size of the final forged part, then be placed in the bottom die. The impact of the top die on the billet drives it into the required forged shape. Steel Forgings from a few ounces to 60 lbs. can be made in this way.
Closed-die forging can produce an almost limitless variety of shapes in most alloys, like of steel, aluminum, titanium and other alloys. These forgings are regularly produced on hydraulic presses, mechanical presses, and hammers. Because metal flow is restricted by the die contours, this process can yield more complex shapes and closer tolerances than open-die forging processes (see open die forging vs closed die forging). Most engineering metals and alloys can be forged through closed die forging technique. Those materials include carbon and alloy steels, and stainless, aluminum and copper alloys, and certain titanium alloys.
Why Use Closed Die Forging? What are the Advantages?
Closed die forging is capable of producing both symmetrical and non-symmetrical parts. While the initial costs can be quite high, it is still the most cost-effective method for high volume production. The closed die process is commonly found in the agricultural, electronics, aerospace, automotive, commercial, manufacturing, semiconductor, construction, hardware, and food processing industries.
- Closed die forging process can forge parts in most metal alloys.
- This kind of forging has low recurring costs for the different parts, making it one of the most economical methods to use.
- Due to its economical advantages, this type of forging process is very popular in the automotive and tool industries.
- In comparison to many other machined parts, closed die forgings have a 20 percent higher strength-to-weight ratio.
- This forging process requires little to no machining. As a result, people are able to save significant time and money when using it on a project.
- Closed die forgings of stainless steel, titanium, aluminum and other metals have the ability to create several different 3-D parts with a variety of shapes, sizes and weights.
- Due to its unique flexibility, this type of forging process is one of the best processes for designs and shapes that are elaborate and complex.
