Wall thickness has a significant impact on the pressure die-casting process. Thinner walls mean the part can cool and solidify faster, leading to lower cycle times. It requires a lot of control over the injection pressure and speed to make sure the mold is completely filled and no defects arise. There’s also the danger of porosity or shrinkage because the interior will solidify slower than the exterior.
Additionally, having uneven wall thicknesses can cause another batch of problems, like warping or residual stresses in the final part because of the different cooling rates. That’s why we usually recommend balancing your wall thickness. It will increase your chances of producing a stronger part, with less material usage, part weight, and defects, and creating an all-around high-quality casting.
