Plating bleed-out definition

Plating bleed-out. Marking on sheet metal where two surfaces in close contact have retained moisture from the plating process that causes streaking. Pin Push: Distortion or protrusion caused by ejector pin pushing into part more than normal. Pitting: Discontinuities in the material surface that result from the removal of roll inclusions and/or oxidation. The resultant surface, although discontinuous, is either removed or neutralized.
