METHODOLOGY ASSESSMENT OF THE GATING SYSTEM NUMERICAL DESIGN OF HIGH-PRESSURE DIE CASTING WITH REGARD TO THE MATERIAL APPLICABILITY
Original language description
High pressure die casting is a precision casting method that comes closest to the ideal effort of directly transforming the base material into a finished product. Casts produced by high pressure die casting are characterized by high quality, even if they are prone to internal inhomogeneity. The internal inhomogeneity of the casts is, among other things, caused by entrainment of air, gases and vapors inside of the gating system by the melt and their entrapment in the melt volume and distribution in the mold cavity, and thus also in the volume of the cast. The primary factor in reducing the gas and vapors entrapment by the melt is the correct design of the gating system. In general, the geometry of the gating system depends on the design of the cross-section of the gate. Calculation of the gate area is not explicitly determined and there are several mathematical formulations for its determination. The submitted article describes the methodology of the gating system design and assessment of selected methods of gate geometry calculations with regard to the subsequently determined volume of the gating system, the utilization of the metal batch per one operation and the size of the necessary machine locking force.
