Note: Annealing a zinc wire prior to forming pellets for air rifles

Objective:

Annealing a zinc wire prior to forming a special high velocity air rifle pellet 

End Product:

air rifle pellet 

Equipment:

  • Ambrell 2.4 kW induction heating system, equipped with a remote workhead containing two 0.33µF capacitors for a total of 0.66µF
  • An induction heating coil designed and developed specifically for this application.

Materials:

Zinc wire 0.18” (4.5mm) dia 

Temperature:

572 ºF (300 ºC)

Frequency:

253 kHz

Testing:

A fourteen-turn coil is used to heat 3.9” (100mm) of zinc wire. The wire is placed in the coil for 5 seconds to reach the desired condition just prior to the forming process. 

Benefits:

Induction heating provides:

  • Reduced hardness of pellets to prevent damage to the forming dies

  • Reduced production time

  • High efficiency, low energy cost

  • Fast and controllable heat

  • Hands-free heating
