A torch isn’t as precise as induction nor is it repeatable; induction heating is highly repeatable, uses less energy than a torch and offers instant on/off heating
The coil design enabled the part to be raised into the heating coilfrom the bottom. The design was also made to ensure it will work well within the customer’s current setup.
Induction heating enables precise application of heat, faster process time and production rates and the ability to be incorporated into existing production lines
A single turn helical coil is used to heat the gear. The gear is placed on a spindle and rotated at 300-350 RPM’s.
A five turn helical coil is used heat the screw threads. The screw is placed in the coil, heat is applied for 8 seconds to achieve a 2” long zone at the required hardness.
To harden various size ends of hand held marking stamps. The area to be hardened is 3/4” (19mm) up the shank.
Hardening the cam outer surfaces with induction results in uniform heating for uniform results, one coil can be used for many geometries, consistent results from piece to piece
A five turn helical coil is used to heat the gear end of the shaft to 1700ºF
Heat cast iron pulleys to 1600ºF(871.1ºC) in order to achieve a hardness of 55 Rockwell C.
A two turn helical coil with an internal quartz tube designed to scan the length of the blade is used to heat the blade to 1850ºF (1010ºC) to achieve the desired hardness.
The hardness desired is between 45 to 55 Rockwell C, and should be measured 0.062"(1.6mm) from the cutting edge.
