The main activity of Metalock Malta Ltd now and Metalock Italia srl, has always been the cold repair of mechanical parts in cast iron that have been subjected to internal pressure, cracked or fractured.
The Metalock process can be applied where welding is not practicable, as in cast iron, ineffective or potentially harmful.
Over the years the activity has been complimented with insitu mechanical repairs, maintenance and revisioning of industrial and naval equipment and engines.
The Metalock method is used for cold repairs to cast iron/cast steel and non-weldable metals, and is based on the limitation and locking of cast cracks, as well as the reconditioning of damaged casts.
After the METALOCK process re-machining of repaired components may sometimes be necessary. Machining services are normally performed in specialised workshops or in-situ using portable machines.
