Crack Repair for Heavy Metal Components | Metal Stitching
RA Power Solutions, one of the oldest companies in New Delhi, India, specializes in repairing cracks in heavy components made of cast iron, bronze, aluminium, and cast steel using the cold metal locking and metal stitching process.
Metal stitching and locking are reliable method of repairing cracks without welding, avoiding the excessive heat that welding generates. Heavy components often get damaged due to accidents, and in many cases, replacing them is not feasible. New parts can be expensive, take a long time to manufacture, or may belong to obsolete equipment.
Our experienced technicians carefully remove the damaged portion of the component, create a new casting to match the original, and assemble it on site. The repaired parts are then secured using high-quality metal keys and locks.
For example, we successfully repaired the MAN main engine model SMIT MAN R666W, restoring the engine block, cylinder liner, and piston with cracks ranging from 75 mm to 190 mm.
