Design considerations for Gold plating

Gold plating can be a relatively expensive process, particularly when compared to other surface finishing techniques. This is because gold is a precious metal and the process requires specialized equipment and expertise.
Gold plating can be relatively soft compared to other surface finishes, which makes it susceptible to wear and damage over time.
The availability of gold can sometimes be limited, which can affect the cost and availability of the plating process.

The Justway Gold plating process

The process can improve the product's electrical conductivity and thermal conductivity, making it suitable for use in electrical and thermal applications. Let’s break down the basic steps for Gold plating a part:

Clean and prepare the material to be plated
The material is then treated with an acid or alkaline solution to activate the surface
The material is then immersed in a bath of gold plating solution and connected to a power source
Control of process parameters
Rinsing and drying
Buffing or polishing
Check the material for any defects or flaws
