GRAVITY/PERMANENT MOLD CASTINGS

We begin the gravity process by preheating the mold to 150 – 200 degrees Celsius (300 – 400 degrees Fahrenheit) to ease flow and reduce thermal damage to the casting. The mold cavity is then coated with a refractory material or a mold wash, preventing the casting from sticking to the mold and prolonging mold life.

We produce a variety of gravity mold castings, from aluminum to copper.
