What is Sand Casting?

Sand casting as a technology has been around for millennia, and is selected as a preferred method to produce shaped parts that weigh less than a pound, to very large parts. The process is versatile and cost effective, even for low volume runs because of tooling cost. Nearly any part configuration that can be made in another material can be reduced to a pattern and created as a sand casting.

Principle of centrifugal casting

图片
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.

Trunnion Type Centrifugal Casting Machines

图片
Trunnion type centrifugal casting machines use a mold or flask that is supported and rotated by four trunnion wheels. These machines are used for producing castings that have lengths longer that their diameter.                          Common castings produced on trunnion type include bushings, bearings, cylinder liners, piston rings, pipe, and steel tubes and sleeves. Our automatic centrifugal casting machine all adopt trunnion type as main engine.

J517 horizontal cantilever centrifuge

图片
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...
