    Precision Power Plant Parts Casting Foundry

    TDC Alloys is an ISO 9001:2015 certified, premier Power Plant Parts Casting Manufacturer in Gujarat, delivering high-temperature, wear-resistant, and creep-resistant castings for thermal power generation and utility installations. From coal pulverization and boiler steam generation to turbine power conversion and ash handling, our parts withstand severe continuous thermal shocks up to 1,150°C and aggressive abrasion across power utilities in Gujarat.

    Our foundry manufactures heavy-duty power plant castings from 10 kg up to 3,000 kg per piece. Utilizing 3D solidification modeling, medium-frequency induction melting, and computerized solution annealing, we cast boiler burner tips, coal mill bull ring segments, bowl mill grinding rolls, and high-pressure steam valve bodies throughout Gujarat.
