Our powder coating services provide a continuous, protective color finish on parts using evenly applied, heat-cured paint in several color options like red, orange, blue, black, and several other colors and in matte, gloss, and textured finishes. A powder coat provides a durable and vibrant finish to materials like aluminum, steel, and other metals that protect it from weathering, water, impacts, and other stresses. A variety of applications use powder coating, such as kitchen appliances, automotive painting, lawn and garden products, architectural and construction products, drum hardware, bicycle parts, and much more.

What is Powder Coating?

Powder coating is the process of applying protective coatings to surfaces by applying dry, electrostastically charged powders of typically thermoset or thermoplastic polymer onto a grounded surface using a specialized spray gun, forming a thin and even coat. Once applied, the coated surface is heated and/or cured to fuse the powder into a durable finish. Powder coating protects metals surfaces from corrosion, scratches, and other types of damage, and also provides a vibrant color finish.

    Powder Coating Process - How Does Powder Coating Work?

    Powder coat application, as opposed to traditional liquid coating, is achieved through a multi-step process. The steps of the powder coating process typically include:

    • Powder Preparation
    • Surface Preparation
    • Powder Application
    • Curing
    • Quality Control

    Powder Preparation

    The polymer, hardneners, colorants, and other additives are blended together in a mixer. This mixture is then extruded, hardened, and then converted into small pieces, which are then milled into a uniform, flour-like fine powder. 

    Surface Preparation

    The surface receiving the powder coat is cleaned and prepped by removing dirt, oils, and other contaminants. This may involve sandblasting, chemical degreasing, or other mechanical and chemical methods on a metal surface to ensure the surface is prepared for coating. It is essential to remove any contaminants to ensure a clean, smooth application. 

    Powder Application 

    The dry powder is applied to the surface, typically using a specialized spray gun that electrostatically charges the powder particles. The charged particles are attracted to the grounded surface and form a thin, even coat. A variety of nozzles help cater the powder coating process to unique part shapes, and in some instances the spray gun is replaced with a fluidized powder bed for commercial powder coating volumes.


    Once the powder has been applied, the surface is then cured by heating it to a high temperature, typically between 350 and 400 degrees Fahrenheit. This fuses the powder into a smooth, durable finish. Newer powder coating blends allow for UV curing, which hardens the powder coat in just a few minutes at lower temperatures using ultraviolet light. This method is suitable for a variety of heat-sensitive materials and is also more energy and time efficient.

    Quality Control

    After the curing process, the coated surface is inspected to ensure that the coating is smooth and even, and that there are no defects or imperfections. Any necessary repairs or touch-ups are made at this stage.

    It's important to note that these steps may vary slightly depending on the specific application and the type of powder being used. The specifications for each step will also depend on the specific requirements of the project, such as the type of surface being coated, the desired thickness of the coating, and the intended use of the finished product.

    Powder Coating Finishes

    The finish on powder coated parts come in the same range as conventional paint, and is capable of dead-matte to full-gloss appearances depending on the specific polymer blend and powder coating process used. Xometry’s powder coating services offers standard matte finishes for our powder coated parts, unless otherwise specified in notes attached to your quote. If you require a custom finish coating be sure to reach out during the quoting process and our fabricators will achieve the exact finish you need.

      Improved Durability & Lifespan

      Powder coating provides a protective layer on the surface of the material that is more durable and resistant to wear, abrasion, and corrosion than liquid coatings. Powder coating can also extend the lifespan of the material, as it is less prone to chipping, peeling, or fading than liquid coatings.

      Enhanced Aesthetics

      Powder coating can provide a smooth, even finish that enhances the appearance of the coated material and can be applied in a variety of colors and finishes.

      Environmental Friendliness

      Powder coating is a dry process that does not produce volatile organic compounds (VOCs) or other harmful emissions, making it a more environmentally friendly option than liquid coatings.


      Powder coating can be a more cost-effective option than liquid coatings, as it requires less material and produces less overspray, leading to lower material and disposal costs. 

      What Products Can Be Powder Coated?

      Powder coating can be applied to a wide variety of products, and is only held back by how evenly the dry particles adhere to a given surface. Some examples of products that are regularly powder coated include:

      • Automotive parts like car and truck wheels, bumpers, internals, and other components
      • Appliances such as refrigerators, washing machines, and dryers
      • Metal furniture such as tables, chairs, and outdoor patio furniture

      What Products Can't Be Powder Coated?

      It is important to note that the suitability of powder coating for a particular material may depend on its specific characteristics and the coating process being used. In some cases, it may be possible to apply a powder coating to a material that is not typically suitable, but this may require the use of special coatings or pretreatment processes. That being said, there are generally some product categories that cannot be powder coated, such as

      • Plastics, as the powder does not bond well to the surface and may cause the plastic to become brittle.
      • Wood, as the powder does not adhere well to the surface and may cause the wood to become damaged.
      • Glass, as the coating process may cause the glass to become brittle or shatter.
      • Non-metallic materials like rubber, fabric, or paper, as powder does not bond well to these surfaces.

      Design Considerations for Powder Coating

      When surface finishing a product with powder coating, there are some key design considerations that must be taken into account, such as:

      • Tolerances & coating thickness
      • Material surface
      • Color
      • Cost

      • Tolerances & coating thickness:  The thickness of a typical powder coat adds .006”-.012” of surface thickness, which can throw off some low-tolerance builds or through-hole diameters. The thickness of the powder coat should also be appropriate for the intended use of the part – too thin of a coat may not protect the part, while too thick of a coat may result in warped tolerances and uneven surfaces.
      • Material surface: parts with porous surfaces may require special primers or other treatments to ensure proper adhesion of the powder coat. Also, ensure that all surfaces are properly degreased, cleaned of contaminants, and are dry and smooth to achieve the best results. 
      • Color: color can impact the overall appearance of the finished part, so it is important to carefully consider the desired color and ensure every part is powder coated in the same method and with the same coating powder. Different powder blends will result in different end colors, which may cause unintended color mis-matching and an inconsistent look. 
      • Cost: though economical, powder coating and its cost can vary based on the size and complexity of the part, as well as the desired finish and color. Some complex parts will require more attention, and therefore labor and time to powder coat, where it may take less resources to simply plate the part.
