Note: Hardening the end of steel hand-held marking stamps

Objective:

To harden various size ends of hand held marking stamps. The area to be hardened is 3/4 in (19mm) up the shank.

End Product:

Steel hand-held marking stamps

Equipment:

Ambrell 30 kW induction heating system, equipped with a remote workhead containing eight 1.0‚ μF capacitors for a total of 2.0‚ μF An induction heating coil designed and developed specifically for this application. 

Materials:

Steel stamps 1/4 in  (6.3mm), 3/8 in  (9.5mm), 1/2 in  (12.7mm) and 5/8 in  (15.8mm) square 

Temperature:

1550 °F (843 °C)

Frequency:

99 kHz

Testing:

A two-turn channel coil is used to cover the range of steel stamps being heated. The 5/8 in  steel stamp is heated for 60 seconds to reach 1550 °F (843 °C) and the desired hardness. Smaller parts will also heat easily

Benefits:

  • Faster process time and production rates

  • Hands-free heating that involves no operator skill for manufacturing

  • Controlled precise application of heat
