Centrifugal casting is that the liquid metal is injected  to the mold of high-speed rotation.Under the action of centrifugal force, the metal liquid is full of mold.Centrifugal force makes the liquid metal in the radial well with casting and formed a free surface of casting.The centrifugal casting can obtain cylindrical inner hole without core.It is conducive to rule out the gases and inclusions in liquid metal ,which improves the mechanical and physical properties of casting.

Advantage: 1 Gating and runner system are almost no metal consumption, which Improves process production rate. 2 Production of hollow castings can be without core, So In the production of long tubular castings can greatly improve the metal filling ability and reduce the ratio of casting wall thickness to length or diameter. Simplify the production process of sleeve and tube casting. 3 The casting’s density is high , there is less  defect such as porosity and slag inclusion, so it has high mechanical properties. 4 It’s convenient to product cylinder and composite metal casting, such as Steel sheath, double metal roll, when metal castings, it can improve the filling ability of metal by centrifugal force, so it can produce thin wall casting. Disadvantages: 1 There are some limitations in production of special castings. 2 The inner hole diameter of casting is not accurate, the surface of inner hole is rough and poor quality, machining allowance is big. 3 Castings are prone to gravit...

The structure of J517 cantilever centrifugal casting machine is horizontal. It is made up of host, 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. The host consists of the base, turntable, adjustable-speed motor, bearing pedestal, main axis, driving gear and ejector system. Host is the core component of cantilever centrifugal casting machine, which makes the turntable rotate. It can realize the centrifugal casting. The mold is fixed on the turnplate. The main axle is stepless speed regulation so that the equipment can be able to meet technical requirements of casting with different diameter. 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...

The structure of J513 cantilever centrifugal casting machine is horizontal， It is made up of four parts, which are Host,  electric control system, water cooling system and Safety protection cover. Host is the core component of cantilever centrifugal casting machine, which makes the turntable rotate. It can realize the centrifugal casting.      With converter motor driving main axle rotate by belt. It has widely speed range. The main axle is stepless speed regulation so that the equipment can be able to meet technical requirements of casting with different diameter.      With using casting lathe bed, the machine runs more smoothly. The ejection mechanism is driven by pneumatic linear actuator. When the host stops the casting will be pushed out from the die pipe.      In the casting process, pipe die and mold can be cooling by manual control.      The control unit use PL...

Summary Eight-stations cylinder sleeve centrifugal casting machine is widely used for castings of cylinder sleeve。The whole machine is made up of rotary working platform，the automatic cleaning device，the automatic spraying device，the automatic pouring device，Pipe pulling device，mold cooling system and temperature measuring device. It has the following advantages: 1.A high degree of automation 2.Occupying less area 3.High productivity It is propitious to large-lot production of cylinder sleeve. F eatures 1 Cantilever centrifugal casting machine Cantilever centrifugal casting machine is the core part. On the rotary working platform there are eight host machines which are regular distribution. Converter motor drives the main axis rotate with belt. The main axis makes mold rotate and then complete the centrifugal casting. The mold is fixed on the turnplate. Speed of mainshaft can realize stepless speed regulation so that the equipment can be able to fulfill technical requir...

Summary The tradition cylinder liner production enterprise mainly uses many single cantilever type centrifugal casting machines in production. This is typical Labor-intensive industry. The feature is unstable quality, high labor intensity and poor working conditions. With the development of society, we need the higher quality products, the lower Product costs. Our machine has high efficiency, fully automatic and stable production process. So it can meet the new requirements. Single-station fully automatic centrifugal casting machine adopts the host+ multi-station auxiliary, which structure is integrated. The host control by VFD. The auxiliary equipment control by servo and include cleaning, spraying, pouring, cooling and pulling device. The main machine’s speed is adjustable and steady in the high speed. It is advanced spraying technology in multistage and multispeed. The critical technical parameters are monitored and adjusted in the process of casting, which ensure the casti...

Three-station fully automatic centrifugal casting machine adopts the three hosts+ multi station auxiliary integrated structure. The three hosts which control by VFD are in parallel arrangement. The three hosts share a set of auxiliary equipment and casting device. Auxiliary equipment control by servo and include cleaning, spraying, pouring, cooling, pulling pipe. The whole process control automatically. The main machine’s speed is adjustable and steady in the high speed. It is advanced spraying technology in multistage and multispeed. The critical technical parameters are monitored and adjusted in the process of casting, which ensure the casting technical parameters repetition and consistency. It eliminates the influence of artificial factors to the casting technical parameters. So it ensures the intrinsic quality of the casing casting stability The equipment has less area, more production efficiency and fully automatic operation. All of these are very suit for Single spe...
