A large cast iron character include : thick wall, pouring molten iron and more, heat capacity, freezing for a long time, easy to produce a variety of defects, such as sticky sand, shrinkage deformation, large castings defects appear sticky sand.

2020 CNC machine tools and basic manufacturing equipment industry will reach a new height, the development of these two industries must be based on the premise of the casting industry, therefore, these two sectors in progress.

These parts can vary greatly in size and weight, ranging from a couple ounces to several tons. Some smaller sand cast parts include components as gears, pulleys, crankshafts, connecting rods, and propellers.

Pressure die casting creates parts with no joints by eliminating other processes such as welding and fastening. Integral fastening elements such as bosses and studs can be included.

Precision machining is a process where material is removed from a component to a very high tolerance. The tolerance held depends on the machine but most percision CNC machines will not have a problem holding a tolerance of 0.002" or 0.005 MM (ish).

Precision casting's entry, a cast magnesium used in a new model of vacuum lightweight, vertical produced by Oreck, demonstrated both a creative use of magnesium and innovative manufacturing technology.
