What Is the Powder-Coating Process?
Powder coating is a process that involves applying powder paint onto a component to prevent corrosion. Various options are available for powder coating, including color and texture choices.
Many companies are increasingly adopting powder coating as a high-quality and durable finish. Because it helps to maximize production, improve efficiency, and simplify environmental compliance. Powder coatings can serve functional (protective) and decorative purposes and are available in an almost limitless range of colors and textures. Technological advancements have also led to improved performance.
The Guidance On How to Powder Coat?
To apply powder-coating, electrostatically charged particles are spread over the substrate’s surface. A feeder unit regulates the powder flow, sending it to an electrostatic gun. The gun diffuses the powder into a cloud-like form. The particles are then charged through a low-amperage power unit, causing them to adhere to the substrate’s surface.
After applying the coating, the workpiece must be cured in a specially designed oven. This process results in a protective layer and promotes adhesion. Typically, The curing process requires a temperature of 400 degrees Fahrenheit for 30 minutes, but the specifics may vary based on the type of powder coating.
Preparing the surface cleaning thoroughly in advance is crucial to achieve a successful powder coating result. It includes removing grease, oil, dirt, or other materials through various chemical, physical, or mechanical methods to ensure a clean surface and optimal coating adhesion. By pretreating the workpiece with chemical compounds, the coating’s performance, durability, and resistance to corrosion can be significantly enhanced.
Powder Coating Materials
Powder coating offers endless possibilities. Virtually any material can be powder-coated, but metal reigns supreme in this industry.
At Enze, we recognize that each project is unique and has its own requirements. Our powder coating processes are designed to offer various material options, ensuring we can meet your specific needs with precision and expertise.
Steel is often used in powder coating due to its strength and durability. To ensure surface quality, pretreatment is necessary to remove oils and greases, followed by post-treatment using sandblasting or phosphating.
Aluminum’s lightweight and corrosion-resistant nature makes it ideal for powder coating in the aerospace, automotive, and architectural industries.
The process of aluminum pretreatment is crucial, involving cleaning, etching, and laying a chromate or non-chromate conversion coating. This surface treatment significantly improves adhesion and provides an additional layer of corrosion protection.
Copper and brass are expensive but famous for their unique aesthetic finishes. They are commonly used in decorative industries such as hardware, lighting fixtures, and architectural accents, where their visual appeal is crucial to the product’s design.
Copper and brass require thorough cleaning to remove tarnish and oxides before powder coating.
Plastics can be challenging to powder coat due to their lower melting points than metals; however, recent advances have greatly enlarged the possibilities.
MDF and wood are popular substrates for powder coating due to their smooth surface. They are used in cabinetry, furniture, and decorative projects, providing a durable finish resistant to scratches and moisture.
Powder Coating Finishes
The finish on powder-coated components can range from dead-matte to full-gloss, similar to conventional paint. This depends on the typical polymer blend and powder coating process operated. Enze provides standard matte finishes for powder-coated components unless specified otherwise in the attached notes to your quotation. If you need a custom treatment, please communicate during the price offering stage, and our team will ensure that you get the exact finish you require.
Design Tips for Powder Coating
You should consider the following elements during the powder coating process:
Thickness
Tolerances
Surface
Color
- Quantity
Cost
Thickness: Powder coating thickness measurements can be taken before and after curing. The best method is determined by substrate type, powder coating thickness range, component shape, and cost.
Tolerances: A typical powder coat adds between .006″ and .012″ thickness, affecting low-tolerance builds or through-hole diameters. The thickness of the powder coat should suit the part’s intended use – a coat that is too thin may not protect the part, while a coat that is too thick may cause warped tolerances and uneven surfaces.
Surface: For porous surfaces, use special primers for proper adhesion. Ensure all surfaces are cleaned, degreased, and dried for in excellent conditions.
Color: Color choice is critical in powder coating. Use the same method and powder for consistency to avoid color mismatches and an inconsistent finish. Manufacturers frequently use the RAL color as a basis for their selections.
Quantity: Depending on the quantity, manual or automatic coating is preferred. For samples, manual coating saves time and cost, while for bulk production, coating in automatic lines is a better choice.
Cost: Powder coating costs can vary based on part dimensions, complexity, finish, and color. Complex parts need more energy, workers, and time, while plating may require fewer resources.
Color Standards
Color Standards refer to a standard system for assigning numbers to different colors. The system allows for unified color management and application across various industries. The color standard international system includes Pantone, RAL (the German International Standard), and NCS (Natural Color System). These number systems are widely used in design, printing, powder painting, textiles, plastics, and other industries.Which provides specialists with unified color reference and communication tools.

Powder Coating FAQS
Dry powder coating is a versatile and easy-to-apply alternative to liquid paint. Its application method ensures a uniform coating, even on products with sharp edges or narrow recesses. This quick process minimizes waste, and any oversprayed powder can be reused. Unlike liquid paint, a satisfactory finish can be achieved with just a single coat of powder coating. With a wide range of coatings available for various applications, including RAL color matching, powder coatings can outperform liquid paint and provide many options for the end application.
Furthermore, powder coatings are more environmentally friendly than liquid paints.
Powder coating provides strong protection for parts and surfaces and enhances their appearance. Instead of merely painting over scratched metal surfaces, applying a powder coating over the entire part will result in an even finish. Powder coating is a quick, efficient, and long-lasting alternative to liquid paint that can provide years of protection. It’s an excellent solution for revitalizing scratched surfaces and restoring them to their original condition.
Powder coating can help metal resist corrosion.
Powder coating is a reliable, sturdy finish that effectively shields metal surfaces, parts, and products from corrosion. It is important to note that while powder coating cannot protect surfaces that already have rust, it can prevent rust from forming if applied and maintained correctly.
Two primary types of powder coating are available at Enze: thermoset and thermoplastic. Thermoset is durable and resistant to chemicals, while thermoplastic is flexible and easy to repair. The three standard options are
- epoxy (the most durable and expensive),
- polyester (less expensive but less durable), and
- urethane (least expensive and least durable).
Proper preparation, material selection, and usage conditions determine the longevity of powder coatings, which usually last 15-20 years.
