Metal stitching has been a recognized
method since 1938 and has saved multiple machine frames, pumps, presses and
engines from scrapping. The key characteristic of the metalock process is that
it involves no heat strain in its application.
Metal-stitching process of damaged engine frame. This
type of repair is a life lasting repair.
In-Situ Metalock Repair
cracked or otherwise damaged cast parts always represents a great challenge as
cast iron can only be welded to a limited extent. MAN PrimeServ On-site
Recovery uses a special Metalock/Masterlock procedure as a viable alternative
to welding that today is the preferred method in industry and marine shipping.
This procedure enables
us to specialise in the cold repair of damaged industrial components made from
cast iron, steel and aluminum. The Masterlock method is a cold-repair process
that avoids the stress problems frequently associated with welding and, more
importantly, maintains the original alignment, which lessens the requirement
for re-machining following repair.
International Association has developed and tested a new stainless key (MN555)
to facilitate component repair at high temperatures of up to 550 degrees
Celsius. The key is corrosion resistant and can also increase a repair’s return
Metalock/Masterlock procedure offers many advantages and:
is a cold
process that eliminates thermal stress and resultant component distortion
on-site repair that eliminates the need for disassembly and off-site transport
high pressure-tight seal that protects against oils and gases
the downtime of valuable equipment
recognised by classification societies
the need to purchase new, expensive cast-iron parts
