Pot metal, also known as zamak or monkey metal, is a common material used in automotive and other industrial applications. While it may seem like a durable material, pot metal can be prone to pitting, scratches, and other types of damage over time. However, the good news is that pot metal can be restored through a process known as pot metal restoration.
The Pot Metal Restoration Process
The pot metal restoration process typically involves the following steps:
Stripping the old plating: The first step is to chemically or electrolytically remove the old plating from the pot metal part. This is done to expose the underlying metal and prepare it for the restoration process.
Cleaning and preparing the surface: Once the old plating has been removed, the surface of the pot metal part is cleaned and prepared for the next steps. This may involve sanding, grinding, or other techniques to remove any pitting, scratches, or other imperfections.
Applying a soft copper plating: After the surface has been prepared, a substantial soft copper plating is applied to the part. This copper plating helps to fill in any remaining pits or low areas and provides a smooth, even surface for the next steps.
Re-sanding and finishing: Once the copper plating has been applied, the part is re-sanded and polished to achieve a smooth, even finish. If there are any remaining pits, scratches, or low areas, they may be filled with silver solder during this step.
Applying the final plating: After the part has been sanded and polished, it is ready for the final plating, which is typically a layer of nickel or chrome. This final plating provides a durable, long-lasting finish that can withstand the wear and tear of everyday use.
