Ellisse... It means oval in Italy. The forged pegs are made of round steel that has been heated in red until approximately 232°F (1,100°C) and crushed the cross section into an oval shape at once with a powerful force of about 1 ton. By applying strong pressure to hot steel, the pegs are created with superior strength. Forging is a type of plastic processing method for metal processing.By hitting the metal with a hammer or other to apply pressure, it crushes the air inside the metal, finalizes the crystals, refining the direction of the crystal, increasing the strength and molding it into the desired shape.Since the ancient time, it has been used as a manufacturing technique for knives, weapons, and hardware.The material of the metal is formed by applying pressure to a mold or similar to a plastic fluid.The fiber flow continuously makes the tissue more dense and less likely to form castings than casting, making it possible to create coarse materials with excellent strength.
