Advantages and Disadvantages of Closed Die Forging

Otherwise known as impression-die forging, closed die forging relates to a process in which a metal is placed between shapes that are customized to fit the metal. Such metal is then pressed and hammered, causing it to fill and flow in the cavities of the custom-shaped dies. This forging classification is one of the most frequently used processes for forging steel components.

Closed die forging can produce longer-lasting and stronger products because it works well with the steel’s internal grain structure.

Why is Closed Die Forging Frequently Used?

Pros

The noteworthy advantage offered by closed die forging is that it needs little-to-no machining at all. It simply makes use of the force produced from all the pressing and hammering during the closed die forging process. Likewise, it uses the right amount of heat to deform the steel so it can accurately fill the die mold or impression.

Closed die forging can be used to create parts made out of almost all metal materials, including steel, aluminum, and countless other metal alloys. Thanks to no material limitations, parts can be made to fit your exact needs. Other advantages of closed die forging are:

  • Capacity to create near net shape and sizes
  • More accurate and steady impressions
  • Can achieve several shapes and dimensions have tight tolerances
  • Superior mechanical properties and better surface finish

Cons

Just like everything in life, there are some disadvantages to products – that includes closed die forgings. Some of the common disadvantages include:

  • Size limitation
  • It is not cost-effective for short production runs for the high tooling cost
  • Shape limitation – For these components with an irregular shape, it is also not available
  • Such complex products can only be made by casting

Technical Specifications: Closed Die Forging

Closed die forging uses a controlled procedure with a culmination of alloys and heated metals to create the desired shape. Without an appropriate forging die lubricant, effective and economical closed die forging is unattainable. To know more about the technical specifications of this type of forging, please read on.

Mechanical Characteristics of Closed Die Forging

Alloys Used

Closed die forging is a type of forging that has exceptional mechanical characteristics – one of which is adaptability to the different kinds of an alloy such as copper, bronze, and aluminum. Aside from allows, it can also adapt or mold various kinds of steel like stainless steel, tool steel, and alloy steel.

Specifications

When using closed die forging, the tooling division must go through the center of the forging and should not run through the side. The reason for this is that the forging must be detachable from its divisions.

The different cross-sections must be equal to avoid extreme disparities in the flow of the metal. Additionally, a closed die forging uses low and wide rib features. To avoid quick tooling cracks or wear in forgings, manufacturers use large radii. Moreso, an ample and suitable draft angle should be provided wherein compliance of the 5° to 7° for steel and 3° for aluminum are mandatory.

Benefits and Finishing Options

Closed die forging is known for its economical procedure compared with welding assemblies. Other notable benefits include high production speed, use of highly homogeneous steel and alloys, and high rating when it comes to good repeatability. As for the finishing options, closed die forging allows blasting, vibra-polishing, hot-dip galvanizing, and electrolytic zinc plating.

Factors that Guarantee Only the Finest Forging Die

The finished product of a closed die forging is affected by several factors. The most common of which is the accurate process of application of die lubricant at proper intervals. Similarly, the forging result may also be affected by the decrease in friction during the forging procedure. Friction can satisfactorily be decreased by using appropriate polished dies and die lubricants.
