Metal Stitching and Metal Locking Company in India | RA Power Solutions
When heavy machinery parts such as engine blocks, pump casings, gearbox housings, and other cast components suffer cracks or breaks due to stress, impact, or wear, replacing them can be expensive and time-consuming. That’s where metal stitching and metal locking services become a cost-effective and efficient solution.
Metal stitching and metal locking are advance cold mechanical repair techniques that repair cracked or damaged cast iron, steel, aluminium, and other metals without generating heat. Unlike welding, which causes heat stress and distortion, these procedures maintain the part’s original integrity and alignment while restoring strength and longevity.
