We are having finish issues with our die cast parts- we originally wanted a smooth surface for plating and were then told by our mfg that smooth was not possible and that a light matte finish was better for plating regardless.
Long story short- getting the manufacturer to get us the parts (two parts, need the finish to match) with a matching surface texture has been a nightmare since they had the dies (molds?) made at different shops - and our customers do not like the matte finish- would prefer polished or brushed.
Is it possible to die cast zinc (zmak 3?) with a smooth finish? Not a mirrored finish, but a smooth surface suitable for plating straight out of the die or with minimal manual labor afterwards? Right now, to get a smooth finish, a lot of material needs to be removed due to the texturing on the surface.
Any help is greatly appreciated.
