Closed die forging usually is precision-machined to achieve net shape or near-net shape finished products. When you use forging, less post-forging operations are needed because near-net shape products are formed and created. Otherwise said, you’ll save a substantial amount of time and effort when you use this type of process.
Also known as the impression-die forging of titanium, aluminum, steel, or other types of alloys, closed die forging can practically produce a wide array of 3D shapes that differ in weight from ounces to tons. This type of forging is primarily created on hammers, mechanical press, and hydraulic presses with powerful capacity that can reach up to 50,000 pounds.
As the name suggests, two or more closed dies comprising impressions of the shape are merged together as forging stock that endures plastic deformation. Since the die contours control the metal flow, closed die forging can produce closer tolerances and more difficult shapes as compared to open die forging processes.
One of the best things about forging is its adaptability and versatility with its components because the manufacturer can use any form of raw metal or even alloys using this method. It doesn’t matter if the user needs small or medium-sized metal parts – closed die forging can quickly produce them.
Closed die forging involves the most complex components with long and thin portions that integrate small webs and relatively high vertical projections like bosses and ribs. Likewise, it also includes simple elements to forge secure disc-like configurations, block-like shape solids, and spherical shape configurations. While most of these parts are commonly symmetrical, others integrate all kinds of design components such as pockets, cavities, holes, protrusion, flanges, and a whole lot more. These are used to produce a very non-symmetrical forging. Additionally, portions of the materials used can be easily curved and bent in one or more planes.
