Usually about 0.10mm (0.004″). We can plate much thicker than that (and often do), but as the coating thickness increases, so does the edge buildup on the ports and lead-in chamfers etc. There are also technical reasons to avoid excessive thicknesses, but there are sometimes economic reasons to plate cylinders regardless of thickness, for example if the cylinder can’t be replaced or if no pistons are available in the size that you need. Please contact us to talk about this if it is applicable.
