Metal Stitching | Metal Locking | Repair of Cast Iron by Metal Stitching – RA Power Solutions

When cast-iron or aluminum engine blocks crack, the traditional fix—welding—is often expensive, risky, and destructive. At RA Power Solutions, we specialize in advanced cold repair techniques—metal stitching and metal locking—that restore structural strength without applying heat, requiring machining, or dismantling equipment.

With the improvement in repair technology now, it is possible to repair the crack in cast iron, steel, or aluminium component by metal stitching and metal locking process. The main feature of repair of crack or damaged casting by metal stitching, metal locking, and metal surgery is that process does not require disassembly of the equipment and taking the crack or damaged part to the workshop.

What Are Metal Stitching & Locking?

Metal Stitching is a precise, cold repair method. Technicians drill a series of aligned holes across the crack, insert metal “keys” or studs into a dovetailed pattern, and tighten them so they interlock—effectively sealing the fracture and restoring rigidity.
Metal Locking reinforces the stitching with custom-shaped metal inserts that prevent the crack from spreading further and enhance the repair’s long-term durability

New Casting Inserted for Repair of Engine Block

RA Power Solutions has the team of experience technicians. They can travel to the site with tools and consumables required for metal stitching and metal locking undertake the repair.We repair cracks by metal locking and metal stitching while maintaining the original profile.
