Film and sheet extrusion machinery supplier Macro Engineering & Technology Inc. and 
sister company Macro Technology have expanded their refurbishing capabilities at their Mississauga, Ont. headquarters. 

The refurbishing process involves evaluating the existing dies to assess damages (if any), strip the plating,
remachining the die surfaces (if required), polishing and re-plating. The process is said to yield dies that are as good as new. All the cleaning processes are done manually to ensure that the die is not overheated unnecessarily to prevent metal warpage or cracking of the plating.

“We have seen a significant increase in request for refurbishing customers’ existing equipment. If the equipment is worn, several things can happen: chance for polymer degradation increases, polymer flow distribution worsens over time, and melt temperature gradient is also questionable.” Says Jim Stobie, Macro’s CEO. “After we refurbish our customers’ dies and retrofit old screws, their equipment performance improves again. This is the most cost-effective way to maintain productivity and product quality.”
