Casting Repairs
Metalock UK Casting Repair Division is the largest and most successful company in the world specializing in the cold repairs of cracked or broken industrial components manufactured from Cast Iron, Steel and Aluminium using the unique Metalock Process.
This is a cold repair process that avoids the normal stress problems associated with welding and maintains the original alignment, which limits the need for re-machining following repair.
Metalock International Association has developed and tested a new stainless key (MN555) to enable repairs to components working at high temperatures of up to 550 degrees C. The key is corrosion resistant and can also increase the return of strength of a repair.

Step two (Metalock Repair)
The Metalock process is based on sound engineering principles which have been accepted for more than a century.

Step four (Metalock Advantages)
Some advantages of the repair by the Metalock method are:
- Work can be, and usually is, done on site, with usually a very great saving in time and dismantling.
- Maintains alignment and original surfaces.
- Dampens and absorbs compression stresses and spreads tensile strains.
- Provides a good expansion joint on such jobs as cylinder liners.
- Distributes the load away from fatigue points.
- Maintains relieved condition of inherent internal stresses where these were the cause of the fracture, or partial cause.
- Provides a low co-efficient of expansion in the relation to the repaired metal.
- The repair being completely cold does not require the application of hear which could, and often does, introduce fresh stresses.
