WebMay 29, 2024 · There are three types of bending on a press brake. The relationship of the end tool position to the thickness of the material defines each type. These three types are air bending, bottoming, and coining. 1. Air Bending. The flexibility and relatively low pressure required by air bending make it a popular choice. In the Air bending process, … WebJun 14, 2005 · Coining Dies Coining dies create the part's shape by squeezing the metal under extreme pressure. Coining also can reduce the metal thickness. Coins (metal currency) are created with the coining process. A simple round metal slug is placed into the die and forced to flow into a given shape by compressing it (see Figure 3 ). Restrike Dies
