Refurbished Heat Transfer Rolls—Good as New

Even with laser welding, the supplier determined that the super-finish required for application could not be achieved. However, Menges recommended refurbishing the roll to save both production time and replacement costs.

“They removed the outer shell, installed a new one, and applied the tungsten carbide super finish to the roll,” Varley says. “However, once they removed the shell they found a number of other problems in the roll’s internals. There were some leaks that they were able to repair, and they also re-balanced the roll. After the refurbishing, which was done fairly quickly, we had a virtually brand-new roll for less than half the price of fabricating a complete replacement.”
