The steel and spheroid foundry as well as the aluminium foundry have been approved and certified by several classification societies or associations for the manufacture of cast products. VULKAN Technologies Pvt. Ltd. has approvals issued by the classification associations BV Marine (Bureau Veritas), DNV (Det Norske Veritas), ABS, GL and LRS and IRS. The independent certification and regular audits provide an assured quality level at VULKAN Technologies Pvt. Ltd. and ensure quality of a high class according to international standards.
In addition, VULKAN Technologies Pvt. Ltd. has also been given clearance as a supplier of cast parts made of steel castings, spheroid castings, stainless steel castings, aluminium sand castings for the companies Alva Laval, ABB, MAN, Cummins, Schwing Stetter and other renowned customers.
The modern foundry for steel castings and spheroid castings is equipped with high-power medium-frequency induction crucible furnaces; at present, this facility can cast 120 tons of steel per month in the form of the most diverse steel and spheroid castings with a raw weight of 30 up to 500 kilograms. When it comes to manufacturing sand castings, as a result of using Croning sand cores, one can achieve the maximum possible casting precision and comply with the most stringent tolerances.
In the aluminium foundry, parts are manufactured using the gravitational die method and the sand finished casting method. Casting alloys that may be used as options are AlSi10Mg, AlSi12, LM25, LM6 and LM9. Cumbersome test methods such as manufacturing specimens for testing the mechanical properties of the material technologically, metallographic examinations, chemical corrosion investigations as well as controlled measurements using emission spectrometry ensure the quality of the cast products. The creation of 3.1/3.2 test certificates is standard according to DIN EN 10204. The aluminium foundry of VULKAN Technologies Pvt. Ltd. is the first one in India that has been certified by Lloyd’s Register (LR).
The centrifugal casting process is being launched at present for the manufacture of symmetric rotary components such as, for example, armature housings for industrial applications. Cast parts manufactured using this process are tentatively planned to be delivered from the factory in 2012.
For the production of flexible and highly flexible couplings, VULKAN Technologies Pvt. Ltd. has its own vulcanisation facility with 18 vulcanisation presses that work on the basis of the most modern transfer moulding technology. Over and above this, the Indian subsidiary also operates its own compound manufacture for the most diverse elastomers. With a stringent demarcation between the production zones, silicon and natural rubber compounds may be manufactured at one location.
VULKAN Technologies India Pvt. Ltd. has earned a reputation both nationally and internationally as a supplier and manufacturer of high-quality castings and elastomer-metal compounds.
