RA Power Solutions, with over four decades of expertise, offers advanced crack repair services using metal locking and metal stitching techniques. These cold-process methods are ideal for repairing cast iron and cast steel components without welding, and they preserve structural integrity without introducing heat-induced stresses.

The Metal Lock and Metal Stitching process has the following advantages:

I) In case of a cracked or damaged component, there is no need to send it to the designated workshop. Our technicians visit the site and undertake the repair of cracks by the metal locking and metal stitching process.

II) Metal locking and metal stitching a proven methods of repair for cracks. This permanent solution uses a cold process to repair cracks and generates no heat, unlike welding.

III) If a large portion of the casting is damaged, you can replace it with a new casting that has the same design, profile, and metallurgical properties using metal stitching and metal locking.

We have provided services of crack repair and repair of damaged casting for the last 4 decades all over the world. We are cost-effective and execute the repairs with a guarantee.

Industries widely use cast iron in heavy industrial and marine applications because of its excellent strength and heat resistance. However, even the toughest cast iron components may develop cracks or break due to accidents, overload, stress, lubrication failure, or fatigue. If not addressed correctly, such damage can lead to catastrophic failure of machinery, costly downtime, and expensive replacements.

At RA Power Solutions, we specialise in cast iron metal surgery and crack repair. We use advanced techniques that restore structural integrity and performance without the drawbacks of traditional welding methods.

A leading shipping company operating in the Middle East approached us for assistance. One of their auxiliary engines, a Daihatsu 6DK20, met with an accident. A connecting rod bolt failure breaks the engine block window, where the cover is fixed, into multiple pieces.

Cast Iron Metal Surgery

Metal surgery refers to a group of cold repair techniques designed to restore cracked or broken cast iron parts without excessive heat. Unlike welding, which generates heat and can distort the component, metal surgery methods preserve the material’s original alignment and dimensions. These processes include metal stitching, metal locking, cold stitching, brazing, fusion techniques, and controlled stress relief treatments.

Since the time was short, we manufactured a casting measuring 15 x 15 inches, and two technicians boarded the vessel. The job of repairing the cast-iron engine block was executed in a recorded minimum time. The engine is performing satisfactorily.

We have all the latest tooling available for the repair of cast iron. The parts of the diesel engine are to return to their original shape and profile. The metal stitching and metal locking process, followed by us to repair the cast iron, gives more strength than the original casting.

Cast iron crack repair requires a skilled approach, tailored to the type and severity of the cracks present. By employing metal surgery techniques like cold stitching, metal stitching, fusion welding, brazing, and stress relief heat treatment, it is possible to restore the functionality and structural integrity of cast iron components.

If you encounter cracked cast iron machinery or parts, consult us. We are professional metallurgical experts who specialise in cast iron repairs. crack repair services, ensuring the best possible outcome.

A cracked engine block can bring major downtime and costly replacements, but in many cases, it doesn’t need to be scrapped. At RA Power Solutions, we specialise in professional cracked engine block repair, using advanced metal stitching and metal locking techniques that restore structural strength without the need for complete block replacement.

Broken Engine Block of Yanmar Engine

Cracks in the engine block often develop due to accidents, thermal stress, mechanical overload, or material fatigue. Rather than enduring long delays and high replacement costs, our expert team can deliver reliable repairs on-site, even while the vessel is sailing.

What Causes Engine Block Cracks?

Engine blocks may crack due to several reasons:

Overheating: Excessive temperature causes uneven metal expansion and fractures.
Thermal Cycling & Mechanical Stress: Repeated heat and vibration cycles weaken the block over time.
Coolant Freezing: Ice expansion inside coolant passages can split the metal.
Physical Damage: Accidents or impacts can initiate cracks.
