Reducing customer scrap rates using technology
A custom die caster needed help producing a high-volume front cover casting, that was plagued with high scrap rates and impregnation costs.
Elba Tool and Magma were contacted to propose modifications that would reduce or eliminate problems caused by excessive porosity.
After several iterations of analyses the shrinkage porosity was significantly reduced. Part geometry modifications would be required to eliminate or reduce the remaining porosity.
Elba Tool modified the part model and 3D part geometry was submitted for approval by OEM prior to proceeding
Running process simulations again showed a significant reduction in porosity and hot spots. Although not completely eliminated, analysis of the data showed the results to be more than acceptable
Dies were redesigned with new casting and gating geometry and built accordingly. Cooling was placed strategically, and manifolds with valves were added to the tool to allow adjustments as conditions dictated.
Initial sampling showed the following results:
