Plating and Surface Treatment Options

Plating your compression springs can make a huge impact on their esthetic look and, sometimes, improve their performance. There are several reasons to why a spring might need plating, but you want to make sure you really need it before going through the extra expense. This is why we have provided the properties of the most common plating and finish types we offer; so that you can determine whether you really need it or not.

 

WHY PLATE YOUR SPRINGS

 

There are several reasons you might want to plate or coat your compression springs. The most common reasons are listed below.

  • To protect common steel wire springs from corrosion thus evading the cost of having them made of a stainless steel wire type.
  • To make non-conductive springs conductive or make conductive springs even more conductive (so they can transfer electrical energy, such as the springs in a battery compartment).
  • They are also plated for decorative measures, so you don’t only have the bare material.

 

If any of these is your case, keep reading to determine which plating option is best for you or contact our team of engineers to help you make this decision. If your spring is enclosed, not visible, or isn’t exposed to harsh environments, you do not need to go through this additional process.

  • Passivate (Stainless Steel Springs ONLY)

 

Note: The passivation process is not actually a plating or coating and it can only be done to Stainless Steel springs. This process chemically removes the free irons and forms a passive oxide “film” layer which further improves corrosion resistance and cleans the material. When exposed to air (oxygen), the stainless steel spring undergoing passivation will have a chemically inactive chromium oxide surface.
