The Metalock Process is a repair system based on fundamental engineering principles, an emergency service on offer throughout the marine & industrial world.
The Metalock Process is accepted as the method of repairing all cracked, broken and damaged castings in Cast Iron, Aluminum and Steel for a wide range of industries in a multitude of applications.
The repair consists of peening into prepared apertures, layers of Metalock Keys. The Keys are formed into a multi-dumbell 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. Metalock Keys are manufactured in a variety of sizes to suit each individual job. The high strength of the Metalock Keys ensures the return of a high percentage of the original strength.
The advantages of the Metalock repair are that no heat stresses are introduced, no distortion occurs and in many instances machining is unnecessary. It is valuable in emergency situations, reduces downtime and avoids the replacement of expensive castings.
Repairs can be carried out in-situ or in our workshops.
The Metalock repair process is a cold repair method used to restore cracked metal components without welding. The procedure involves drilling and preparing openings across the crack, installing specially designed Metalock keys to reconnect and strengthen the damaged sections, and fitting overlapping Metalock screws along the crack to provide additional reinforcement and sealing. The repair is completed by caulking the entire installation to ensure structural integrity, pressure tightness, and long-term reliability, effectively restoring the component's strength and functionality.
