1) solutions can be used to create complex geometries pad, including internal Goth external shapes arid.
2) Some parts casting operations produce net shape. Any additional manufacturing parts are needed.
3) can be used solutions.
4)for any metal that can be heated to the liquid state.
5) There are several methods highly suitable solutions to this mass.
6) Resolution is the easiest and fastest (technique) from drawing (design) production.
Disadvantages of Sand Casting:
1) Limitation on mechanical properties.
2) Porosity (empty spaces inside the metal – metal strength decreases).
3) Poor precision dimensional and surface finishing.
4) safety hazards for people and environmental problems. A very difficult
5) Ending pattern of thin and small parts.
