Assessment of Suitability of the Design of Gating System with the Use of Simulation Software
2017
The quality of thin wall castings produced by metal die-casting
depends on the coherence and consistency of various aspects
influencing the process of casting cycle. The qualitative
properties of castings should already be considered in the
design phase of construction of the gating system. The
simulation software is an effective facility for the initial
revealing of defects of the design phase. The assessment of
casting cycle by the means of simulation predicts an incidence
of defects of the casting core in the design phase and
therefore reduces both the incidence of defects in the
production and the costs while the production efficiency is
increased. The article deals with the assessment of the design
of the gating system for a particular casting type. The filling
of mould cavity, casting solidification and time course of
temperature changes occurring in the selected locations of
gating system were defined as parameters indicating the
assumptions of design accuracy. Simulation tests were carried
out in the NovaFlow&Solid program. The tests resulted in a
conclusion evaluating and describing the adequacy of structural
design of the gating system.
