“…In the second experimental campaign, other parameters were slightly changed, such as upset pressure, temperatures of the melt and of the die, even if the precise evaluation of the impact of these parameters goes beyond the aim of this work and is discussed in [18]. The same paper, however, shows that a RMS is by far the most relevant parameter that explains the differences of the casting properties.…”

“…The manufacturing of the castings was realized by two different plants. Both the machines have 7355 kN locking force, while they have different plunger diameters of 0.080 and 0.070 m [12,18]. The die was designed to exacerbate the defect generation [22].…”

“…Hence, coefficient α 1 , representing the variability of the achieved peak load, is strongly affected by the geometry of the die. Indeed, the slope of the fitting model will be low in the case of optimized geometries [6], while it will be steeper in the case of "defect-generating" dies like those adopted in this work and in [12,18]. Also, the friction between the die and the flowing metal has a similar effect: in the presence of high friction forces, the flow is perturbed unless a proper selection of the plunger motion profile is chosen, thus exacerbating the defect generation with badly planned plunger motion.…”

The availability of tools for predicting quality in high pressure die casting is a challenging issue since a large amount of defects is detected in components with a consequent worsening of the mechanical behavior. In this paper, a tool for predicting the effect of the plunger motion on the properties of high pressure die cast aluminum alloys is explained and applied, by demonstrating its effectiveness. A comparison between two experiments executed through different cold chamber machines and the same geometry of the die and slightly different chemical compositions of the alloy is described. The effectiveness of the model is proved by showing the agreement between the prediction bounds and the measured data. The prediction model proposed is a general methodology independent of the machine and accounts for the effects of geometry and alloy through its coefficients.

PurposeCasting is one of the well-known manufacturing processes to make durable parts of goods and machinery. However, the quality of the casting parts depends on the proper choice of process variables related to properties of the materials used in making a mold and the product itself; hence, variables related to product/process designs are taken into consideration. Understanding casting techniques considering significant process variables is critical to achieving better quality castings and helps to improve the productivity of the casting processes. This study aims to understand the computational models developed for achieving better quality castings using various casting techniques.Design/methodology/approachA systematic literature review is conducted in the field of casting considering the period 2000–2020. The keyword co-occurrence network and word cloud from the bibliometric analysis and text mining of the articles reveal that optimization and simulation models are extensively developed for various casting techniques, including sand casting, investment casting, die casting and squeeze casting, to improve quality aspects of the casting's product. This study further investigates the optimization and simulation models and has identified various process variables involved in each casting technique that are significantly affecting the outcomes of the processes in terms of defects, mechanical properties, yield, dimensional accuracy and emissions.FindingsThis study has drawn out the need for developing smart casting environments with data-driven modeling that will enable dynamic fine-tuning of the casting processes and help in achieving desired outcomes in today's competitive markets. This study highlights the possible technology interventions across the metal casting processes, which can further enhance the quality of the metal casting products and productivity of the casting processes, which show the future scope of this field.Research limitations/implicationsThis paper investigates the body of literature on the contributions of various researchers in producing high-quality casting parts and performs bibliometric analysis on the articles. However, research articles from high-quality journals are considered for the literature analysis in identifying the critical parameters influencing quality of metal castings.Originality/valueThe systematic literature review reveals the analytical models developed using simulation and optimization techniques and the important quality characteristics of the casting products. Further, the study also explores critical influencing parameters involved in every casting process that significantly affects the quality characteristics of the metal castings.
