This application method employs a powder spray booth, powder feeder, electrostatic spray gun, and, depending on the type of gun used, a power unit.

Electrostatic deposition (ESD): For most metal parts, the coating material is applied via electrostatic spray deposition.

There are two main methods employed by manufacturers and finishing service providers- electrostatic deposition (ESD) and fluidized bed powder coating. The type of coating material being used in a coating application, in part, determines the application method. Application StageĪs discussed in the next section, there are two types of powder coating materials that can be applied. However, generally, they are constructed of paper or plastic film coated with a pressure-sensitive adhesive, which allows them to adhere to the substrate and protect the covered area from coming into contact with powder material during powder coating operations. These aforementioned products are available in a variety of standard and custom shapes and forms. If the component design requires certain sections to remain uncoated, masking products (e.g., masking dots ) are applied to the substrate prior to the application stage. Wash stations are capable of spraying parts with hot water, steam, detergent, and other pretreatment solutions to clean, chemically prepare, and rinse the surface before coating. Oil, grease, solvent, and residue can be removed from a part’s surface with weak alkali and neutral detergents in dip tanks or wash stations.

However, some of the steps that are commonly employed during this stage include cleaning, rinsing, etching, blasting, and drying, and the most widely used equipment includes wash stations, blast rooms, and dry-off ovens. A complete preparation treatment is mainly dependent on the material being coated. If a surface is not sufficiently prepared, any remaining residues and deposits could affect the adhesion of the powder and the quality of the final finish.

Preparation Stageīefore the application of any powder coating material, the surface of the substrate must be cleaned and treated to ensure that the part is free of dust, dirt, and debris. There are three stages: surface preparation, coating application, and heat curing. During the process, the powder is applied to a substrate’s pretreated surface, melted, and then dried and hardened into a protective/decorative coating.

In contrast to the liquid coating process, which utilizes a liquid coating suspension, powder coating is a dry finishing process that employs powdered coating material. Overview of Powder Coat Process and Equipment The method includes a preparation, application, and curing stage, and, at a minimum, utilizes a spray gun, spray booth, and curing oven. Powder coating is a multi-step surface finishing process suitable for metal and non-metal substrates. Additionally, the article explores the benefits and limitations of the process and provides some of the considerations manufacturers must keep in mind when choosing a coating service provider.

While each coating process has its advantages and disadvantages, this article focuses on powder coating, outlining the basics and the necessary components and mechanics of powder coating technology. The requirements and specifications demanded by a particular powder coat-e.g., application environment, substrate materials, sizing, costs, turnaround times, etc.-help determine the type of coating process most suitable for use. However, while powder coatings demonstrate some advantages over liquid coatings, especially in thick or high-traffic coating applications, they are not suitable for all manufacturing applications, such as for thin film or large part coatings. Either process can produce an even, hard finish which is generally more durable, cost-effective, and environmentally friendly than a comparable liquid coating. There are two main methods of powder coating-electrostatic spray deposition (ESD) and fluidized bed application. This finishing process is suitable for various materials, including metals, plastics, glass, and medium-density fiberboard (MDF), and can provide both functional and decorative surface coatings in a wide range of colors, finishes, and textures that are not readily achievable by conventional liquid coating methods. Powder coating is a finishing process in which dry, free-flowing, thermoplastic, or thermoset powder material is applied to a surface, melted, and hardened into an even coating.
