History of Superkino Equipments Pvt. Ltd.

Late Mr. Sitaram Shah, Chairman of the company launched a non-ferrous foundry in early sixties, specifically to cater an engineering units in and around Bombay. To build on this foundation, a full fledged machine shop facility was set up where most of the castings were machined before being shipped to the customers, in late sixties.
