When is comes to special machining Mallock have
the knowledge and the
expertise to machine akwords parts. Since we developped onsite machining Mallock
use
their equipments to do the inhouse machining that needs special treatements.
When is comes to boring machine, lathes, drill presse, milling, presses,
keyway, honing, welding, grinding, electroplating, metallizing
and mecanical repairs Mallock as the expertise and the knowledge.
Mallock can modifie equipment to have better life, better range of wear and
tear,to improve productity.
Mallock is in bussiness for 35 years to serve industries like petrolium,
plastic,rubber, ships , vessels, woods, pulp and paper,
hydro, mines, quarries,reffineries,mismachine parts, machines shops,
bridges, locks, steel , titanium, mills, steel mills, copper mills,
tranportation, textiles, railroad.
Mallock will repair, compressors, granulators, motors, tractors, extrudeurs,
turbines,pumps, presses, convoyeurs,
slitters, shafts, paper rolls, printing rolls, valves, etc.
Mallock has a world wide expertise in vessels
repair such as , dampers,
sleeves, pumps, hulls, roders, gear boxes
fluid drive, piping, engin blocks, crankshafts, crankshaft polishing.
Mallock will go as far as Halifax and Newfounland to do some vessel repairs.
Mallock can weld steel engin blocks cylenders.
Mallock can repair hydraulic pumps. Mallock developped over the years an expertise
in welding, stitching,
brazing cast iron, nodular cast iron,grey cast iron,malleable cast iron,
compacted graphite cast iron,white cast iron and alloy cast iron .
Stitching cast iron is preferable to all because of the absence of heat ,
expansion, cristalization and deformation of the parts to be repaired.
Cast iron have a thermal conductivity therfore the stitching application
is
preferable to all techniques.
The thermal expansion can be also great depend of the alloy content in the
cast iron so stitching applies.
To prevent the overheat of cast iron we use the cold weld application call
stitching. Cast iron have a tendancy to develop hard spot
on the welded zone HAZ so again Stitching is well appropriate. |
