The purpose of this study is to identify relationships between the values of the fluidity obtained by computer simulation and by practically implemented tests. Three types of molds were used: 1. horizontal three-channel mold designed in the accordance with the methodology of the Measurement Systems Analysis which is useful for determining repeatability and reproducibility in the analysis, 2. vertical mold ? the lyre and 3. the spiral mold (Curry spiral). An aluminum - silicon - copper alloy was model material. The...

Cast iron, the oldest type of ferrous material for injection molding is also currently the most widely used material in foundries. In particular, this good technological properties (excellent fluidity, low tendency to shrinkage and their formation, low propensity for stress) as well as acceptable mechanical properties and good workability. Similarly, its physical properties and prefer it allows to produce castings with excellent specific characteristics, particularly heat and heat resistant, wear resistant and cas...
