Clinching Tool for Joining Metal and Plastic Components

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a device for creating a secure connection between a metal and a plastic component using a process called clinching. The device features a die with a negative mold of the component and a punch that moves into the die. Uniquely, the die includes a ring groove with a diameter larger than that of the negative mold, which aids in the joining process.
