What Is Drop Hammer Forging?
Drop hammer forging is a metal fabrication method employing two impression dies, one on a stationary anvil and the other attached to a moving ram. This method is called ‘drop hammer forging’ because drop hammers are the primary pieces of equipment used throughout the process. In drop hammer forging, the pre-heated metal billet is placed onto the lower die. The ram brings down the upper die, delivering a set number of blows to deform (shape) the hot metal. The number of blows needed will vary depending on the item that is being manufactured. Lastly, the “impression” or cavity of the dies used in the process contains the final shape of the forged product.
Now that you know what drop hammer forging is, here are some of the advantages this focused manufacturing process offers:
The drop hammer process also makes it possible to align metal grains along with potential stress locations, which improves overall strength. The components we make using this process are generally stronger and work for longer in high-stress conditions.
Drop hammer forging is an efficient way to produce specialty components and tools. Examples include:
This manufacturing process allows for the fabrication of items based on specific requirements and needs.
While the drop hammer process offers many advantages, it is ultimately an advanced manufacturing process. The dies, or tooling, needed for the process must be created by a skilled engineer to ensure accuracy. You also need metallurgists to help you determine which metal is best suited for the application, the temperature to which the metal must be heated, and how many impacts are needed for the process. Lastly, the drop hammer forging method may not be the best method for your specific application. Again, an experienced forging engineer can help you decide which forging method will be the most cost-effective and efficient for your unique application.
There is no question that forging plays a significant role in the national economy and provides convenience and comfort to the average American. You can find forgings in passenger vehicles, commercial trucks, aircraft, agricultural machinery, submarines, oilfield equipment, and more.
