What is Metal Stitching and Metal Locking?

Metal stitching and metal locking are specialized cold repair techniques used to restore cracked or damaged cast iron and other metal components without welding or heat application. These methods are widely used in industries where heat-based repairs could cause further damage, distortion, or weakening of the material.

Metal Stitching
Metal stitching is a mechanical repair process that joins broken metal parts by inserting precision-engineered metal stitches along the crack. These stitches restore the strength and integrity of the component while keeping the original structure intact. The process involves:

Drilling holes along the crack in a controlled manner.
Connecting the holes with a milled slot to create a secure stitching channel.
Installing metal stitches or keys that pull the broken sections together, creating a seamless repair.

Metal Locking
Metal locking is an advanced reinforcement technique that works alongside metal stitching. And Enhance the repair’s strength. It involves placing metal locks perpendicular to the crack to distribute stress evenly, preventing further damage. This makes the repair permanent, durable, and capable of withstanding high loads and pressure.
