However they mainly include thin materials such as metal foils plastic foils papers and films. For larger holes or use on thicker gauges of steel more.

Luckily the right punching tooling can help fabricators work with this mix of material thicknesses efficiently. More metal fabricators are venturing into the area of thicker materials so it s not too unusual to see 0 25 in. Material thrown onto a punch press that also accommodates thin material. This tends to equalize the sheet stretching of both halves.

These machines can be either a single head and tool rail trumpf design or multi tool turret design. As part of the cutting stage in metal manufacturing punching metal is.
