Electroplating adds versatility to metal parts. Zinc plating (galvanization) is a budget-friendly choice for rust prevention in automotive fasteners. Nickel plating enhances durability and conductivity for battery terminals, while 18k gold plating offers luxury finishes for jewelry or high-end electronics. Unlike anodizing, plating works on multiple substrates like steel or copper. However, it requires precise bath chemistry to avoid porosity or uneven layers. For example, chrome-plated hydraulic rods combine corrosion resistance with a polished look. Work with certified platers to ensure RoHS compliance and consistent quality across batches.
