Technicians successfully repair broken engine blocks, turbocharger casings, and heavy cast-iron parts using metal stitching, metal locking, and metal surgery.
Welding has become an outdated method for repairing cracks and damaged castings. Technicians do not recommend welding for repairing cast metal or cast iron parts. In many cases, welding creates more serious damage because the process generates excessive heat and stress. RA Power Solutions has been undertaking repairs of damaged engine blocks, steel component repairs, cast iron repairs, and all types of cast components by metal stitching and the metal locking process for the last four decades.


We maintain a separate, dedicated team of technicians who undertake onsite repair of cracked or damaged castings. They use portable tools and high-quality consumables, including locks and keys that we import from the UK.
