A platen (or platten) is typically a flat metal (or earlier, wooden) plate pressed against a medium (such as paper) to cause an impression in letterpress printing.he platen sits between two steel rolls which deliver the moving force to the sanding belt. Sanding heads with a platen are used on finish sanding with papers of finer grits, when the coarser ones are typically used with contact drum type sanding heads. Stock is fed into and out of the machine on a conveyor belt.
Silver plate or electroplate is formed when a thin layer of pure or sterling silver is deposited electrolytically on the surface of a base metal. EPNS stands for Electro Plated Nickel Silver. Nickel Silver (sometimes stainless steel) is the base metal onto which silver is plated. Despite its name, nickel silver contains no silver at all, but is an alloy of nickel, zinc & copper. A layer of pure silver is deposited electrolytically on the base metal to give a silver finish.
