Hardening steel screw threads
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[more about hardening][Applications]
Heat a compacted litz wire bundle for stripping
A three turn helical coil is used for the wire stripping process. The litz wire bundle is placed in the coil for 3 seconds to strip the lacquer 0.75” (19mm) from the end of the bundle. The wire bundle is then scraped with a metal brush to remove the burnt lacquer...
Annealing the end of steel wire on a woven wire mesh
A two turn oval coil is used to heat the woven wire. The woven wire is placed in the coil and heated for 15 seconds to soften a 60” (1.52m) length of the wire 3” (76.2mm) deep. The woven wire is then placed in a press brake for the bending process.[more about annealing][Applications]
Annealing both ends of copper tubing for refrigeration
A four-turn helical coil is used for this annealing process. The copper tube is placed in the coil and power is applied for a total of 7.5 seconds. At 3.75 seconds the copper tube is rotated half a turn to ensure uniform annealing...
