Cracked engine blocks can bring operations to a halt—but replacing them is often expensive, time-consuming, and logistically challenging. Metal stitching, also known as cold metal repair, offers a permanent solution for repairing cast iron or cast aluminum engine blocks without welding or heat distortion.
At Panesar Crankshaft Centre, we provide expert metal stitching of engine blocks across Africa, restoring structural integrity with precision and reliability.
What Is Metal Stitching?
Metal stitching is a cold repair technique that involves inserting a series of specially designed metal locks and stitching pins across a crack to mechanically restore strength to damaged castings. It is ideal for materials that are heat-sensitive or prone to further cracking during welding.
This process is used to repair:
- Engine blocks
- Cylinder heads
- Crankcases
- Pump casings
- Compressor housings
Why Choose Metal Stitching Over Welding?
- No heat input: Avoids thermal stress, distortion, and weakening
- Permanent solution: Restores full mechanical strength to the casting
- Precision controlled: Stitching pattern follows the exact crack path
- Suitable for all environments: Ideal for marine, industrial, and remote settings
Common Engine Block Damage Repaired by Stitching
- Cracks between cylinders or coolant passages
- Fractures from freezing or hydraulic lock
- Stress cracking from operational overloads
- Casting porosity or structural separation
- Crankcase cracks and oil leaks
