There are many important components within a die assembly<\/a> \u2014\u00a0one being a punch stripper. Below, we\u2019ll discuss what a punch stripper is and why it\u2019s important, as well as some different styles to choose from.<\/p>\n

What Is a Punch Stripper?<\/h2>\n

A punch stripper is a part of a die assembly that holds a workpiece in place. It\u2019s typically placed over a punch and attached to the retainer. However, each die assembly is designed differently.<\/p>\n

A punch stripper\u2019s function is to generate enough holding pressure to hold the workpiece in place while the punch retracts from it. There are two objectives here:<\/p>\n

    \n
  1. To create a clean, defined punch or shape in the workpiece.<\/li>\n
