Design for Manufacturing (DFM) in die casting is the process of optimizing part geometry to ensure it can be produced efficiently, with high quality, and at the lowest possible cost. When parts are designed with the casting process in mind, you reduce defects like porosity, warping, and "cold shuts."
Here is a comprehensive guide to the essential DFM principles for die casting.
Bosses are used as mounting points or standoffs. If designed incorrectly, they create heavy masses of metal.
Design Tip: Always "core out" a boss from the back so the wall thickness remains consistent with the rest of the part.
Connection: Connect bosses to side walls with ribs to improve metal flow and structural rigidity.
