Inward material Testing
Process
The Basic Raw Material required for the manufacture of Enamelled
Winding Wires are Continuous Cast Copper Rods, Enamel Varnish
and Thinner. Copper Roads of quality grade with 99.99% purity
is processed form reputed suppliers like M/s. Hindustan Copper
Ltd., M/s.Sterlite Industries (I) Ltd., M/s. Birla Copper etc.
The above companies are maintaining the quality of the Copper
Rods as per IS 12444 88 and/or ASIM:BB-49-92. Relevant Test
Certificates are issued by the Supplier accompanied with each
consignment. On receipt of the Copper Rods essential
tests like Tensile strength, electrical Conductivity and Resistivity
are carried at our in-house laboratory to ascertain the quality
of the material. Since we have not come across any of the
quality problem in Copper Rods, we have purchased any external
agencies for testing.
The Enamel Varnish and Thinner as per IS Specifications is
required from M/s. Dr.Beck+Co.(I) Ltd., accompanied with Test
Reports. Quality tests such as, Viscosity, Solid Contents
are carried out at our own lab. M/s. Dr.Beck+Co.(I) Ltd.,
is having Technical Service Department, which provides assistance
and supervision on trial results.
Quality Control
The plant includes a provision for a modern in-house laboratory
equipped with the test equipments confirming to the relevant
IS specifications. Intermediate on-line and 100% tests of
the end product will be carried out. The results will be properly
documented so as to establish operating norms. Care will be
taken on identify non-conformity and necessary corrective
action is taken immediately to ensure consistency and quality.
