Metal Stitching and Metal Locking is a cold repair process to fix cracked or broken metal parts without using welding or heat. Rather than melting the metal, special stitching pins and metal locks are inserted in the damaged area to tie the crack together and restore the strength of the component.
This repair technique is widely used for cast iron, steel, aluminum and other cast metal components such as engine blocks, crankcases, cylinder liners, pump housings, compressors and turbine casings. No heat is applied so no risk of distortion, warping or further cracks that can happen during welding.
RA Power Solutions has over 47 years of experience in providing metal stitching and metal locking services for marine, power plant, and industrial equipment worldwide. Our skilled engineers use specially designed locks, pins, and stitching keys to repair cracks in cast iron, cast steel, aluminum, bronze, and other metal components. The damaged area is carefully drilled, tapped, and fitted with interlocking metal keys and pins to create a strong, pressure-tight, and permanent repair.
We regularly repair engine blocks, crankcases, cylinder liners, compressors, turbine casings, pump housings, and other critical cast components. This repair method is especially valuable for expensive or obsolete parts that are difficult or impossible to replace. It eliminates the need for dismantling large equipment in many cases, reducing downtime and repair costs.
