The Thermal Transfer roll is manufactured with an 8620 forged steel sleeve, carburized to a depth of 3/8" per side (3/4" on diameter).It is then quenched and tempered to a final hardness of 60-65 Rc. The shell is then fitted to a 4140 heat treated mandrel that has been machined with a serpentine pattern that allows uniform temperature control of 1-2 degrees across the face during operation. Rolls are manufactured for new and replacement equipment.
