We used strictly coining, but air bending when absolutely required. All we used there was air bending.Īnother company I worked for multiplied the material thickness by 6 to give us the die width. Then we had a chart that told us which bend allowance to use depending on whether it was stainless steel, aluminum, or mild steel.
One of the companies that I worked for chose their die by multiplying the material thickness by 8 times. The problem is, it also depends on the tooling and process for your company uses. You can have charts that give you bend allowances for different gauges.
