CAPSTAN is one of a main part in wire drawing factories.
There are available in many forms. They can be made from Ductile Iron, Low Alloy Steel. High wear area is where wire is draw passing capstan. This is a Sliding Wear.
By carefully select material to resurfacing the worn-out area and suitable method to do this, the initial cost might be higher, but your total cost will be much lower. Your profit will be higher!
