The Stitching Process:

  • At first, visible and invisible cracks are identified.
  • The parts are clamped together to bring the parts to their original position.
  • A rectangular hole is made across the fractured portion.
  • This hole is made by drilling and chipping.
  • The Master lock, a large rectangular key of special metal is inserted into the hole.
  • Locking Pins are inserted alongside the master lock to provide a tight and secured master lock.
  • A length of metal stitching keys is inserted on the sides of the master lock to prevent the locking pins from falling out when the casting is subjected to high vibrations.

Advantages of Metal Stitching:

  • No heat stress is induced
  • No Distortion occurs
  • In many instances, machining is not required
  • Invaluable in emergencies
  • Reduces downtime
  • Gas/ Liquid proof repair
