The Closed-die Forging Process – Cooling the Forged Parts

Once the metal is forged (discussed in the previous NEWS), it begins to cool. There are many steps required to separate the component from the rods we use to forge the shape.

Excess metal

As the metal passes through the closed die forging process, excess metal (flash) is removed from the forging by a trimming tool in the press located next to the forging hammer.

Then let the forging cool and wait to move on to the next process.

Heat treatment of forging

Depending on the properties required by the forging stage design standards, there are many heat treatment methods to choose from, the most common being:

· normalization

· annealing

• Hardening and tempering

Rust removal

Parts are usually scaled after heat treatment. The parts are then checked for surface forging defects and, of course, dimensions.

environment

All metal scraped off during the forging process is recyclable. It is crushed and sold back to the factory, which melts the metal and forms a rod for resale.

Health and safety during forging

Handling forged parts is dangerous due to the high temperatures. Therefore, when taking out parts from the forge or during the forging process, all workers should wear ear protection, safety glasses, steel cap boots, flame retardant personal protective clothing for protection.
