Selecting the Best Hooks for Electrostatic Powder Coating

Updated: Jan 8, 2023

Electrostatic powder coating is a process in which a powder coating material is applied to a metal surface using electrostatic attraction. The powder is sprayed onto the metal using a spray gun, which involves a positive charge to the powder particles. The metal surface, which is grounded, attracts the positively charged powder particles, causing them to adhere to the surface.


One of the critical considerations in the electrostatic powder coating process is how to hang or support the coated parts. Typically this is done using hooks made from various materials, including steel, aluminum, and plastic. The hook type can impact the coating process's efficiency and quality.


Here are some of the different types of hooks commonly used in electrostatic powder coating:


  1. S-Hooks: S-hooks are shaped like the letter "S" and are made from a single piece of wire. They are simple and inexpensive, making them a popular choice for hanging parts during the powder coating process.

  2. J-Hooks: J-hooks are shaped like the letter "J" and are made from a single piece of wire. They are similar to S-hooks but are sturdy and can support heavier parts.

  3. C-Hooks: C-hooks are shaped like the letter "C" and are made from a single piece of wire bent into a circular shape. They are designed to hold parts with circular or cylindrical shapes, such as pipes and tubes.

  4. Swivel Hooks: Swivel hooks are a hook used in the powder coating process to hold and support flat or rectangular parts, such as sheet metal or plastic. These hooks allow the piece to rotate or swivel freely, which can help achieve an even, consistent finish. They can also hang parts at different angles or positions as needed. Swivel hooks are a versatile tool in the powder coating process, helping to ensure accurate and efficient coating.

  5. Custom Hooks: In some cases, standard hooks may not be suitable for a particular application. In these situations, custom hooks can be designed and fabricated to meet the application's specific needs.


In conclusion, there are a variety of hooks that can be used when electrostatically powder-coating parts. The type of hook used will depend on the shape and weight of the coated parts and the application's requirements.
