In heavy industries, power plants, marine operations, and mining sites across Africa, cracked cast components can lead to serious downtime and high replacement costs. Metal locking offers a proven, permanent repair method for restoring cast iron or cast aluminum parts—without heat or welding.
At Panesar Crankshaft Centre, we provide specialized metal locking services across Africa, helping clients avoid part replacements while restoring full functionality to critical components.
What Is Metal Locking?
Metal locking is a cold mechanical repair technique used to restore the structural integrity of cracked or broken castings. The process involves:
- Drilling along the crack path
- Installing pre-engineered metal locks and stitching pins
- Creating a mechanical bond that restores strength and seals the fracture
Unlike welding, metal locking does not introduce heat, which can cause further cracking or distortion in brittle materials like cast iron.
What Can Be Repaired with Metal Locking?
- Engine blocks and cylinder heads
- Compressor and pump casings
- Gearboxes and transmission housings
- Marine and locomotive engines
- Heavy industrial machine castings
Industries That Depend on Metal Locking in Africa
- Power generation (diesel, gas, hydro)
- Oil & gas exploration and refining
- Mining, cement, and heavy processing
- Marine vessels and ship engines
- Industrial transport and construction equipment
Wherever cast components are in use, metal locking provides a durable alternative to part replacement—especially when replacements are hard to source or lead times are long.
