Description

Technical Field

[0002] Centrifugal casting is a technology and method for injecting liquid metal into a high-speed rotating centrifugal casting cylinder to make the molten metal perform centrifugal motion to fill the mold and form a casting. The centrifugal mold cylinder is clamped between the screw impeller and the pressure wheel. The cover plates at both ends of the centrifugal mold cylinder are detachable and have openings. The motor drives the impeller to rotate, so that the molten metal rotates centrifugally in the copper sleeve casting cylinder to form a casting. This is a process of centrifugal casting.
