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.
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.
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.
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.
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.
In every closed die forging production, there should always be factors to consider. At Ferralloy, all of these factors are taken into consideration. Get in touch with us today through this link!
