In case of development of crack or broken casting of lower crank case, Entablature, cylinder heads and cast iron parts we undertake crack repair by cold process called metal locking and metal stitching.

The broken casting is replaced by new casting of engine block which is generally of cast iron and is metal stitched and metal locked. The crack repair of engine block, cylinder heads, Turbocharger casing and all cast iron components of Diesel engine are repaired by metal locking and metal stitching process and are guaranteed for satisfactory performance.  The broken casting repair and crack repair of engine parts is done onsite and there is no need of disassembly of the engine. RA Power Solutions is the only company which can undertake repair of crack in cast iron casting while sailing of the vessel and have four decades of experience in metal stitching and metal locking.

Product Details:

Metal stitching is a precise mechanical method of making permanent repairs to broken casting and machine parts.

No heat is used in metal stitching process, thus no stresses are introduced and no post-repair machining is necessary to correct misalignment and warpage. Since there is no heat, metal locking repairs can be made in restricted areas where flames or welding arc is prohibited Repairs are done on location in the plant, without the necessity of major dis-assembly.
