Staking is
a process where two or more parts can be joined by creating an interference fit between the
two pieces. It is a method of fastening by squeezing protrusion formed in one part inside a hole in the second part and then deforming the protrusion. The act of this deformation causes radial expansion of the inner part and locks it in the hole.
Staking is a method of securing parts together with punch and hammer by pushing the surface metal.
Staking can be performed with a wide variety of technologies which are following below.
- Thermal tooling
- Thermal punch or Hot punch
- Hot Air Cold Upset
- Ultrasonic staking
- Cold forming
- Impulse staking
- Infrared staking
