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.
