The Metal Stitching process undertaken by us is a precise mechanical method of making permanent repairs of broken casting and machine parts. We ensure that no post-repair machining is required to correct misalignment and warp age as we don't use heat, which leads to stresses. Further as there is no heat, metal locking repairs can be provided in restricted areas where flames or welding arc is prohibited. Thus, the repair work can be carried out at location in the plant, without the necessity of major dis-assembly.

 

Features:

  • Maintaining production and reducing down time of broken equipment presents many new challenges
  • We provide solutions after a careful analysis and then applying our experience to make a proper, dependable repair
  • The quality and craftsmanship thus achieved have earned for us the recommendation and endorsement of equipment manufacturers, insurance underwriters and inspection services


 

Procedure:

  • Drilling fixture is attached of right angles to the crack
  • A hole pattern is drilled and this is repeated at intervals from ¾ to 1 ¼ inches apart.
  • Metal between each drilled hole is removed by ripping it away with pneumatic tools to form a slot
  • The stock thus removed is narrower than the drilled hole, thus forming a serrated opening
  • Preformed locks of high tensile alloy are inserted in to the slot. These locks are peened into the slots, one on top of the other, to a depth limited by the casting thickness and determined by the strength required.
  • After the locks are installed, holes are drilled, tapped and threaded, fasteners are applied. These are spotted along the entire length of the crack, overlapping one another. Their purpose, in part, is to fill the fracture with new metal and provide a pressure seal
  • Entire repair area is peened flush and finish ground
  • In case of the broken casting, the new casting is manufactured in accordance to the metallurgy of the parent casting. The assistance of pattern maker is taken to manufacture the casting strictly as per the profile of the damaged area
  • The necessary care is taken even for aesthetic look of the new casting which fully gets merged with the old one.

We extend metal stitching services all over the world including countries like Madagascar, Oman, Qatar, Philippines, Bahrain, Srilanka, Bangladesh, Myanmar, Turkey, Nigeria, Greece, Saudi Arabia, UK, Dubai, Malta, Cyprus
