Hot-Dip Tinning

In hot-dip tinning, the workpiece is dipped into molten tin, which deposits as a thin, metallurgically bonded layer on the surface. The layer protects the base material from corrosion, but can be damaged by excessive heat or mechanical stress. For practical purposes: the part must be clean and grease-free, otherwise the tin won't wet properly. Dip it briefly into the melt and withdraw it evenly to get a thin, uniform coating. If you stay in too long or work too hot, the coating can dissolve or become uneven.
