The Piston Velocity Impact on the Filling Chamber Wave Formation of High Pressure Die Casting Machine in 1st Phase of Casting Cycle

Original language description

The quality properties of high pressure die casts are closely correlated with porosity. The formation of porosity is primarily initiated by entrapment of air and gases in the volume of the melt, during its transition through the gating system. This entrapment can occur as a result of an incorrect design of the gating system, incorrect setting of the casting technological parameters, or sometimes a combination of both causes. The setting of the piston velocity in the first and second phase of the casting cycle has the highest proportion of the gas entrapment of all the technological parameters. The submitted article is describing the influence of piston velocity in the first phase of the casting cycle. Velocities are investigated in range from 0.1 m.s-1 to 1.3 m.s-1. First of all, the development of the wave arising at different piston velocities is assessed and the gas entrapment in the melt volume is investigated. Subsequently, the proportion of the gas entrapment in the cast volume at the end of the filling phase is investigated depending on the variable value of the piston velocity in the first phase. In the end, the determination of the piston velocity impact in the first phase on the completion nature of the filling chamber of the machine is derived.
