Forging is a process used in manufacturing. The metal preheats to a certain temperature and then put under high pressure by pressing, pounding, or squeezing. Forgers use carbon, alloy, and stainless steel for their metalworking. Forging are the parts that forging produces and they are very strong. You can find automotive forgings, airplane forgings, and forgings in missiles. That being said, forging is prominent in automotive, construction, aerospace, and national defense markets.
There are several different types of forgings. The first type is open-die. Two flat platforms press the heated metal from the top and bottom. The metal can flow laterally because there is nothing to control it on the sides. The metal’s thickness becomes ununiformed.
Impression die forging uses impressions, which are outlines that are premade onto the platforms. The impressions translate onto the metal, using a more constrained process. Excess metal flows out the sides, called flash, which is trimmed.
The last type of forging is flashless. The die traps the metal so there is no flash made, hence the name. The design of the die and amount of metal has to be accurate to ensure no excess metal comes out.
The different types of forging discussed above can use the following equipment. Hammers pound the metal into the desired shape. They deliver a driving impact of 50,000 pounds in each blow. Presses have a lot more force. Presses can deliver impact of 50,000 tons. They use high pressure to squeeze the metal into shape. The last piece of equipment is an upsetter. They are very similar to presses. Upsetters press the metal horizontally while presses press vertically.
Forgings are very critical because manufacturers use them to assemble safety and reliability pieces. They vary by size and shape so they are found all around us and are important in our lives.
