Two-station fully automatic centrifugal casting machine is composed of the two engines and a auxiliary engine. The two engines which are controlled by VFD are parallel layout. The two engines share auxiliary engine and pouring equipment. Auxiliary engine is controlled by servo and it includes cleaning, spraying, pouring, cooling, casting extraction devices .The whole process are controlled automatically.
The main engineâ??s speed is adjustable and steady in the high speed.The Spraying process is very advanced of multistage velocity control. The key process parameters are real-time monitor and adjusted by automatic control system. So it can ensure the casting process parameters repetition and consistency. It eliminates the influence of artificial factors to the casting process parameters. So it ensures stable quality of the casings.

The structure of cantilever centrifugal casting machine is horizontal. It is made up of engine, electric control system, water cooling system, hydraulic ejector mechanism and Safety protection cover. It can be widely used in large diameter sleeve and cylinder castings production.
Feature
1 The engine consists of the base, turntable, adjustable-speed motor, bearing pedestal, main axis, driving gear and ejector system. 2 Engine is the core component of cantilever centrifugal casting machine. The engine makes the turntable rotate,which completes the centrifugal casting.The mold is fixed on the turntable. The main axleâ??s speed is stepless adjustable.So it meets technical requirements of casting with different diameter. 3 Hydraulic ejector mechanism comprises hydraulic unit, ejector oil cylinder and ejector rod. The ejector oil cylinder drives the ejector rod put out of the casting. The ejector rod is in the middle of main axis. 4 The cooling system includes two parts. The one is mold and casting cooling, another is main shaft bearing cooling. In order to improve the work environment, the water of mold and casting cooling system will be recycling by channel. 5 The mold rotates with turntable driving by AC variable frequency motor.The frequency motor has widely speed range and smooth running.So it meets production process with different castings. 6 Electric control system consists of PLC,HMI,variable-frequency drive,control cabinet and low voltage electrical components. 7 The engine equips safety protection cover, which ensures safety in production.
