Casting is a liquidus for process, includes melting the metal, pouring it in a pre-shaped mould and allowing it to solidify.
Sand casting process is a metal process in which natural sand, containing a proportion of clay to bind the grains of sand together and water, or a pure silica sand with an artificial binder added to it, is contained in a flask
In this project a sand molding arrangement was designed and produced to simulate the automatic sand molding machine.
Sand casting can be economical for relatively small production runs, and equipments cost are generally low
2- Dimensional accuracy is not so good as that of other casting processes.
D = 10 cm
that is available Commercially and to be more efficient , while the stroke is taken L= 10 cm.
1- The sand mold obtained have a good force distribution better than the manually rammed
2- The sand molding process take small time compared with the manually one.
3- This mean that the production rate is increased .
4- This arrangement will be good example for the sand molding machine for the students of the foundry course .
1- The force that form the mold is assumed depending on experience and need several experiments to find the optimum force .
2- The operating valves is working manually and can be changed to operate automatically .
3- Use the compressor with higher pressure rate will help to reduce the molding time.
