Closed die forging is a forging process in which dies that contain a precut profile of the desired part move towards each other and covers the piece in whole or in part. This blog will go into detail about the forging process and capabilities.
The process beings with heated raw material, which is close to the shape or size of the final forged part, being placed in the bottom die. The impact of the top die on the raw material forms it into the required forged form. Parts from a few ounces to 60,000 lbs. can be made this way.
Closed-die forging of steel, aluminum, titanium and other alloys can produce an almost limitless variety of 3-D shapes. 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. Most engineering metals and alloys can be forged via closed die forging. Those materials include carbon and alloy steels, tool steels, and stainless, aluminum and copper alloys, and certain titanium alloys.
Why Use Closed Die Forging?
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.
