We are able to plate objects of up to 20 tonnes in weight, and are the only company in Europe with the capacity to plate such large components.
The grooved rolls are typically used in packaging, can weigh up to 5 tonnes and measure 12 metres in length. As packaging material passes over the rolls at speeds of 1200 metres a minute, these huge components have particularly tight tolerances.
Commercial Director of NiTEC UK, Marcus Hill, said: “Grooved rolls are enormous pieces of equipment. We are the only electroless nickel plating company in Europe to be able to handle such a large component, so naturally we see a number coming through our doors.”
Electroless nickel is the only type of plating suitable for this purpose because it provides a uniform coating, is very corrosion resistant and resilient to wear. Manufactured using mild steel, the grooved rolls are coated with 30-50 microns of electroless nickel. They typically spin at very high speeds and therefore need to be perfectly balanced.
“With other surface treatments, the part would need to be plated and balanced afterwards,” says Marcus Hill. “But with electroless nickel, we are able to balance the grooved rolls, and then plate them, which is far more convenient for everyone.”
