Gravity casting refers to the process of injecting metal liquid into the mold under the action of Earth gravity, also known as gravity casting. Generalized gravity casting includes sand casting,metal casting,investment casting, lost casting,etc. Chivalrous gravity casting mainly refers to metal mold casting, or also called permanent mold casting.
Metal type gravity casting machine is divided into two categories, can tilt gravity casting machine and fixed gravity casting machine. Rotated gravity casting machine can be rotated with die casting, can effectively improve the casting inherent quality, particularly suitable for intake manifold types such as complex casting gravity casting.
