Staking manufacturing process

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
