Why Metal Stitching Is Best for Cast Iron Engine Block Repair

Mpa Power Project18 Dec, 2025Other

Metal stitching is the safest and most reliable method for repairing cracked cast iron engine blocks. This process does not use heat, so it avoids distortion, stress, and further cracking. Special stitching pins and locks hold the damaged area firmly together, restoring the original strength of the engine block. It also creates a permanent, leak-proof repair that can handle high temperature and pressure. Compared to welding, metal stitching keeps the engine block’s shape and alignment intact.
