Quality Policy |
Qualitv Control
Quality is our Defining Factor. Through continuous perseverance of Quality and Quality Assurance
programme, the Company renews its commitment to ensure reliable quality at a
competitive price and in turn earn the customer's satisfaction.
In order
to accomplish this, the company strives:
- To detect and prevent any non-conformance during production
and implement that means to prevent its recurrence.
- To upgrade technology and improve techniques, systems,
procedures and to carry out continuous innovation to meet changing customers'
needs.
- To create most congenial and healthy working environment for
attainment of quality goals with excellence.
- To develop highly motivated and skilled human resources imbued
with strong sense of values and commitment to quality.
- To improve the quality of life of communities living around
the company in particular and society in general by providing basic needs like
health, water, education etc.
Quality - A Motto
JAL
strives to accomplish and maintain the finest quality of products in the
industry. To achieve this purpose, Company utilizes:
- Ultra modem microprocessor based, PLC controlled extrusion
press
- Computerized Spectrometer for instant metal analysis
- Computer aided die manufacturing facilities
- Well equipped physical, chemical, mechanical and metallurgical
testing laboratory and sophisticated R&D Division recognized by the Dept. of
Scientific and Industrial Research, Govt. of India.
The strict adherence to
quality to make the products superior and incomparable in the market forms the
guiding principle for every Jindal employee. Standing testimony to JAL's
achievement is the IS/ISO 9001:2000 certification, awarded by the Bureau of
Indian Standards, the first one in the entire aluminium extrusion industry.
Numerous other National and International awards have also been added to JAL's
list of accomplishments.
At Jindal Aluminium Ltd, quality and reliability
is of primary importance. In order to ensure this, JAL undertakes vertical
intergration to manufacture logs having a specific chemical composition. Raw
materials procured from primary producers have purity of 99.7% and
above.
For log casting, the procedure followed is as stated below
:
- The Melting Furnaces melt the aluminium ingots and the Holding
Furnaces help carrying out the alloying process
- A computerized Spectrometer instantly tests and analyses the
liquid metal to ensure compliance to the established standards
- A uniform and fine grain size is obtained by adding Titanium
-Boron grain refiner
- Subsequently, the liquid metal is filtered through ceramic
foam filters, which eliminate entrapment of any non metallic inclusions
- Finally, an eco friendly Nitrogen Degassing System removes the
gas entrapment andany other form of contamination from the liquid. Top
Homogenising and Extrusion.
The process of Homogenising
ensures a uniform distribution of alloying elements, thereby resulting in
uniform properties. Being an expensive process, homogenising is avoided by many
extruders in India.
- The cast logs are homogenised and preheated before being fed
into the extrusion containers
- The heat and tremendous pressure applied on the solid
aluminium forces it through the extrusion die opening gives a high degree
of structural stability
- The extruded aluminium profiles are then handled on the PLC
controlled conveyor system to prevent any damage to the output
- The products are then stretched in order to straighten and
stabilise them, after which they are cut according to the required
length.
Qualtiy Assurance :
A
full-fledged Quality Assurance and Technical Service Department established
within the JAL premises, along with its state-of-the-art equipments, takes care
of the metal analysis, mechanical testing, metallographic examination and other
studies.
Some of the contemporary tools used are :
- Computerized Direct Reading Optical Emission
Spectrometer
- Carl Zeis Microscope
- Computerized Tensile Testing Machine
- Hardness Testing Equipments
- Romidot Automatic Profile Measuring Systems
- Electrical Conductivity Meter
- Straightness Table
- Hardness Tester
- Ultrasonic Testing Equipment and many more.
JAL performs continous labortory
tests and undertakes quality assurance measures wherever necessary to subscribe
and sustain the standards of excellence.
