Track: EXTRUSION EQUIPMENT - For Large Profiles

ABSTRACT—OMAV supplied in the last years several pieces of extrusion equipment for
presses up to 15.000 Tons to produce heavy profiles up to 120kg/m, and bars up to
260kg/m.OMAV had to engineer and build for this equipment all of the machinery, such as
quench, pullers, saws, and stretchers with a guaranteed high level of performance. For example,
we had to engineer a sophisticated cooling system with the puller that runs through the quench
unit with the cooling switch on to guarantee high quality on the surface, and to drastically reduce
the scrap. In case of hard alloy, heavy bars or big tubes, thanks to water wave cooling, it is
possible to reach high efficiency. The water wave is formed in the lower part of the quench tunnel
– bottom and side walls.For heavy profiles and bars and for hard alloy, we have supplied
stretchers up to 600 Tons. OMAV also engineered a double-blade final saw in order to increase
the final cutting precision. These are just some examples of the main features of the OMAV
equipment for heavy profiles and bars. The challenge for OMAV is to guarantee our customers
higher levels of quality and reliability.
