Open-Die forging is a fascinating process, where the hammer strikes and warps the metal that is placed on a static anvil. Open-Die Forging got its name from the dies that does not enclose the workpiece, allowing it to flow except for the places where the dies have contact. We can see all kinds of metal parts being worked here at a temperature ranging from 500 Fahrenheit to 2400 Fahrenheit!The metal parts are all shaped into the desired shape through the masterly work of hammering and pressing the work-piece.
Open-Die Forging is a very fascinating process indeed. This forging process has also many benefits when it comes to forging a product according to your exact specifications. Other benefits are better fatigue resistance, continued grain flow, finer grain size, improved micro-structure, increased strength and more. Generally, it improves the overall quality of the product being forged.
This video is made in the Sweden based Kihlsteel Company and we can see the process behind Open-Die forging, Ring Rolling and Hammer Forging in a very thorough manner. As for Ring Rolling, it`s also a very interesting process, which we can see in the video. This operation is a hot forming process that makes seamless rings which differ in size from a few inches in diameter and weighing less that one pound, to over 25 feet in diameter and face heights approaching 10 feet. The starting material is always a thick-walled ring.
And the workpiece is placed between two rolls also known as idler roll, while another roll, called the driven roll, presses the ring from the outside. The main applications of Ring Rolling is the production of all kinds of things like a range of ring shaped components which are used in the automotive and aerospace industry as well.
