Below is a list of Forging Presses manufacturers from Fullerton, California. Forging presses are hydraulically powered metal forming machinery that force metal blocks to take the shape of a product by using a mold, extreme force and pressure, and sometimes heat. The force applied stretches metal beyond its yield point, but not so much that it cracks or breaks. The automotive, semi-truck manufacturing, off-highway vehicle and military equipment industries use forged products that are made of any metal, although the most commonly used are alloyed steel, stainless steel, brass, aluminum, tungsten and non ferrous metals.
