Metal Stitching - What Is It
And How Does It Work
Metal stitching describes the process of repairing cracks in cast metals without welding. It uses simple metal stitches to force the repair the metal.
Why Use Metal Stitching?
Primarily because of the need for an alternative to the difficulties encountered in welding.
Cast iron is the most difficult of all cast metals to weld. All electric welding methods have proven to be less than satisfactory and in many cases can cause even more cracks.
Proper cast iron welding techniques require complete disassembly and oven preheat at 900°F to 1500°F.
The main component of metal stitching is the stitching pin.
These pins have evolved over many years from simple threaded bolts through tapered pins to the highly sophisticated threaded fasteners available today.
The other element is locks. They are primarily used in industrial repairs.
Locks have also evolved over the years and have been created in many shapes, sizes and strengths.
Benefits Of Metal Stitching
Using the very latest techniques and CNC machinery, metal stitching gives the following advantages:
Ease Of Use
High Pressure Seal
Compared to traditional welding, metal stitching provides a viable alternative equal in quality, strength and cost.
