GDC Die
Gravity Die Casting (GDC) uses the force of gravity to fill a permanent metal mold with molten aluminum. It produces castings with better dimensional accuracy, smoother surface finish, and superior mechanical properties compared to sand casting, while remaining more economical than pressure die casting for medium-volume production. Vyankatesh Engineering GDC Dies are precision-machined from premium tool steel, thermally balanced to control solidification, and blue-matched on all seating faces to prevent flash.
