Product Description

Stud is a kind of forming method called flanging, which is used to form a straight wall or flange with a certain angle along the edge of a closed or non-closed curve by the action of a die on the plane or curved surface of the blank.


Stud is a kind of stamping process.

There are many kinds of flanging and different classification methods. According to the nature of deformation, it can be divided into elongated flanging and pressing.

Flanging: refers to the forming method of turning the vertical edge along a certain curve at the edge of the flat or curved part of the blank.

The main factors affecting the limit flanging coefficient are: (1) plasticity of materials

The larger the elongation, strain hardening index and anisotropy coefficient, the smaller the ultimate flanging coefficient, which is beneficial to flanging.
