Working with Simulations to Avoid Scrap
Avoiding scrap isn’t just about fixing mistakes; it’s about ensuring they never occur in the first place. While reducing scrap is essential, avoiding it entirely is the king’s way of manufacturing excellence. Simulation, when used correctly, enables engineers to explore thousands of process variations and design alternatives virtually without producing a single defective part.
Key to this proactive approach is the Design of Experiments (DOE) methodology. Instead of running simulations one at a time, DOE enables multiple parameter combinations, gating layouts, overflow positions, and alloy types to be tested in one automated run. The outcome? A statistically analyzed recommendation of what works best, driving decisions with data rather than intuition.
But simulation alone isn’t enough. Horst Bramann warns: “Simulation is waste until you read a result and create a measure out of it.” The true value emerges only when results inform decisions by adjusting tool designs, optimizing process parameters, or justifying the addition of a sensor that would otherwise be considered unnecessary.
Challenges: Human Factors and Complexity
Despite the power of simulation tools like MAGMASOFT, implementation often hits a wall, not due to technical limitations but rather due to organizational inertia. One recurring bottleneck is communication. Too often, simulation results stay within the engineering department, failing to loop back to design or operations. To combat this, Magma developed Magma Interact, a free tool that allows easy sharing of simulation results across teams, including suppliers and customers.
Another challenge lies in competence. Simulation isn’t a one-button solution. It requires both the skill to input realistic parameters and the experience to interpret the results meaningfully. Foundries with experienced engineers tend to get more value from simulations, but as many experts retire, this expertise gap widens. Horst Bramann suggests that simulation must evolve to support less experienced users through AI-assisted tools and knowledge-sharing features that learn from previous simulations.
Turning Data into Knowledge
A Simulation generates mountains of data. The real challenge is converting this data into usable knowledge. As Horst Bramann notes, simulations provide not just validation but a virtual laboratory for learning. Foundries can study the effects of temperature changes on porosity, analyze metal flow under different gating setups, and predict die soldering or distortion, all without touching a casting.
Their Magma Economics module takes it a step further, allowing users to compare casting layouts not only for quality but also for cost and environmental impact. This is crucial in a world where sustainability and profitability are inextricably linked.
And while tools evolve, feedback remains essential. Magma collaborates with foundries to ensure simulation outcomes align with real-world results. Yet, true success comes when foundries establish internal feedback loops by connecting the shop floor with simulation teams to refine assumptions, update models, and continuously improve.
Simulation as a Culture, not Just a Tool
Simulation is central to casting excellence. But its true power lies not in the software itself but in how it’s embedded into an organization’s culture. When simulation informs design, influences tooling decisions, and supports risk mitigation throughout the development cycle, it becomes more than a digital tool; it becomes a strategic asset.
As Horst Bramann concludes, success will depend on two priorities: avoiding waste upfront and turning experience into repeatable knowledge. Simulation enables both, but only if organisations are willing to invest not just in licenses but also in people, processes, and a willingness to embrace the digital future of casting.
