→Types of Stamped Parts
*Coated stamped parts
Stamped parts can be selectively or completely coated with precious metal containing materials based on gold, palladium, and silver as well as
non-precious materials such as tin, nickel and copper <xr id="fig:Dimensional_rangesPlated and contact containing pre-stamped strips and stamped parts"/> (Fig. 3.17). For stamped parts in high volumes like those used as electrical components in automobiles the carrier material is mostly coated in a reel-to-reel process starting with either solid or pre-stamped strips (see also chapter 7.1.1.3). Frequently the prestamped strip will be used directly in further automated assembly of the finished functional component. As an alternative finished stamped parts can be electroplated using barrel and rack plating methods.
Very thin coating layers with tight tolerances are deposited by electroplating. For many applications the high mechanical wear resistance is advantageous. Since even very thin layers are mostly pore-free, these coatings also act as an effective corrosion inhibitor. The type of coatings, the sequence of multiple layers, and the coating thickness, for example for connectors, are chosen according to the requirements for the end application.
