Metal Stitching and metal locking

Following is the process of metal locking, metal stitching, and its advantages.

Process of Metal Locking, Metal Stitching:

Experts accept the metal stitching process as the method for repairing all cracked, broken, and damaged castings in cast iron, aluminium, and steel.

The Stitching Process:

First, we identify visible and invisible cracks.
We clamp the parts together to restore them to their original position.
We make a rectangular hole across the fractured portion.
This hole is made by drilling and chipping.
We insert the master lock, a large rectangular key of special metal, into the hole.
We insert locking pins alongside the master lock. These pins provide a tight and secure master lock.
We insert a length of metal stitching keys on the sides of the master lock. These keys prevent the locking pins from falling out when the casting faces high vibrations.

Advantages of Metal Stitching:

No heat stress is induced
No Distortion occurs
In many instances, machining is not required
Invaluable in emergencies
Reduces downtime
Gas/ Liquid proof repair
