Aluminium Extrusion
JAL has 6 presses of different capacities; of these presses, 2 are of 2200 tons and one each of 750 tons, 1500 tons, 1650 tons and 4000 tons. Installed production capacity is 75,000 MT per annum. JAL has a most modern tool shop capable of producing high quality & intricate dies backed up by an international quality foundry.
JAL is a forerunner in installing several technological and modern equipments in order to obtain high quality profiles. JAL has developed an in-house foundry using Hot Top casting technology imported from USA, with most modern melting and holding furnaces equipped with automatic temperature controllers.
The adoption of such modern technology produces highly refined close grained and oxide free logs which provide a superior finish on the extruded sections.
JAL carries out the following steps to ensure defect free, high quality aluminium extrusions :
- The alloy is instantly analyzed using modern Direct Reading Optical Emission Spectrometer which ensures that the composition remains within close tolerance, thereby achieving the desired mechanical properties.
- The logs are homogenized prior to pre-heating them, in order to achieve superior quality, improved finish and uniform grain structure necessary for anodizing and powder coating processes.
- The dies and toolings used are manufactured by means of latest computerized equipments like Jig Boring Machines, Wire Cut Machines, Spark Erosion Machines and several other CNC equipments.
- Ageing - a thermal treatment is carried out using a high velocity air oven with precisely controlled temperature that results in uniform properties in the extruded aluminium profiles.
- The dimensions of the extruded profiles are checked and ensured by ROMIDOT automatic profile inspection & measurement system.
- The extruded aluminium profiles are finally handled by PLC controlled conveyor system till they are packed. The identification and traceability of the sections are also taken care of by imprinting the company logo on each package.
- JAL possesses in-house facilities for developmental research and innovation to pursue the fast paced advanced scientific development.
Power House of Production
JAL’s efficient operations were facilitated by some of the company’s highly qualified and experienced engineers in consultation with German and American technical experts.
Some of Jindal’s production records have been as follows :
- 12973 MT of aluminium extrusions in 1984-85.
- 28000 MT of extrusions during the year 2004-05, which constituted almost 30% of the aluminium extrusion production in India.
- 45000 MT of extrusions during 2005-06 with an actual turnover of over Rs. 600 crores.
- 46711 MT of extrusions during 2007-08 with an actual turnover of over Rs.800 crores. This is the highest production and turnover achieved by any aluminium extruder in India till date.
- The production target for the year 2008-09 is 50000 MT with a projected turnover of over Rs.900 crores.
- JAL’s 12.04 MW Wind Power project is situated at Chitradurga District, Karnataka.
