Our cast iron repairs are carried out by peening Metalock keys into prepared apertures. The Keys are formed into a multi-dumbbell shape from special nickel alloys. Being highly ductile they can be peened into a metal-to-metal condition and become almost integral with the parent metal of the component under repair.
These Keys are manufactured in a variety of sizes to suit each individual job. The high strength of the Keys ensures the return of a high percentage of the original strength.
Cold Cast iron repairs carried out by this proven method avoid the need for any heat, preventing the introduction of any additional stress or distortion, and in many instances re-machining is unnecessary. It is invaluable in emergency situations, reduces downtime and avoids the replacement of expensive castings.
In the Marine Industry alone, many millions have been saved for ship owners by reducing time lost due to breakdowns or engine failures. It has become commonplace for major items of capital plant and equipment to be saved by our prompt action following a catastrophic breakdown and for the equipment to then go on to give many more years of productive life.
