This includes several types of metallic coatings such as electroplating with trivalent passivation as per ISO 2081, hard-chrome plating, nickel plating, electroless nickel phosphating, hard anodizing, etc.

7. Heat Treatment Services

Heat-treated components are a critical requirement in a number of industries. We specialise in the heat treatment of carbon steel (quenching and tempering), die steel, aluminium, and other metals. With each cycle, time-temperature graphs are generated so that our clients get a complete picture of the heat treatment process followed. The types of hardening processes being done include through hardening, induction hardening, case hardening, and vacuum hardening.

8. Warehousing Services

At our current facility, we provide warehousing services for up to 10,000 sq. ft. for all kinds of industry raw materials and finished goods.
