Despite the fact that cold-chamber die casting is the most widely used process for the mass production of light metal castings, it is also the most expensive method available. In order to realize a cost-effective lightweight design concept, the following factors, according to Magmasoft, must be taken into consideration. As of today, half of the world's production is made using this technology, which continues to grow in popularity as continuous quality improvement is introduced into the manufacturing of automotive components. Following the completion of a development project by the Italian design studio DSM, it was discovered that critical factors must be considered in order to realize a cost-effective lightweight construction concept while also ensuring process reliability for an aluminum die casting with high functional performance requirements in the automotive industry. Figure 1 in the image gallery provides an excellent illustration of what I'm talking about.

An initial virtual investigation has been launched as a preliminary step.

A cover with the highest level of operational reliability in terms of structural strength as well as a hydraulic seal to prevent oil leakage from the engine during operation is the component in question. It was decided by the Italian engineers to conduct a virtual preliminary study of how the tool performed during the manufacturing process in order to detect critical problems with the internal integrity of the component at an early stage (see Figure 2 in the photo gallery).

The virtual analysis of the initial configuration revealed several critical issues, including the fact that the solidification process did notcustom die castingproduce satisfactory results due to isolatedaluminum alloy die castingshrinkage in areas of the component that must maintain a hydraulic seal while in operation; the fact that the solidification process did not produce satisfactory results due to isolated shrinkage in areas of the component that must maintain a hydraulic sealaluminum die casting partswhile in operation; and the fact that the solidification process did not produce satisfactory results due to isolated shrinkage in areas of the component that must maintain a hydraulic seal while in operation. With the goal ofreducing shrinkage porosity to the absolute lowest possible level while also minimizing trapped air, it was decided to investigate various alternative designs for the gating system, with particular emphasis placed on the component's heaviest section. According to Figure 3, switching to a four-cavity mold has also resulted in a reduction in production costs, as well a reduction in tool maintenance costs.

Consequently, the number of critical aspects for internal integrity that were previously present in the heavy section has been significantly reduced as a result of the new layout. To complete the design, it was necessary to define an appropriate thermal control system (see Figure 4 of the image gallery) after a satisfactory layout was identified (see Figure 1 of this gallery).

Simulations must be carried out in order to verify a claim or hypothesis.

Through the use of these tools in conjunction with the corresponding simulations, it was possible to virtually validate both the dimensioning of cooling lines and the process parameters involved in those lines of work. The outcomes, as depicted in Figures 5 and 6, demonstrate that die casting the anticipated improvements, which allow for a direct transition from the design phase to the manufacturing phase, were confirmed by the results of the experiment.
