Automotive Powder Coating Services

A properly applied powder coating can last for many years, especially when the part is correctly pretreated and used in suitable conditions. Marcus uses degreasing, acid cleaning, and zinc phosphate pretreatment before coating, which helps improve adhesion and durability. The finished coating is designed for corrosion resistance, UV stability, and impact toughness, making it well suited for automotive components exposed to regular wear.

The cost to powder coat 20 inch rims depends on the number of wheels, their condition, the amount of stripping or prep required, colour choice, and finish type such as gloss, satin, or matte. Complex wheel designs usually require more labour and masking. Marcus offers in-house powder coating with controlled pretreatment and finish options, so pricing is typically based on part size, surface condition, and coating specification.

Powder coating is commonly used on metal automotive parts such as wheels, brackets, covers, housings, frames, mounts, and other fabricated or cast components. It is best suited to parts that can withstand curing temperatures and benefit from a durable protective finish. Marcus supports coated metal components used in automotive manufacturing, with in-house pretreatment and testing to help ensure finish performance and consistency.

Marcus offers thermoset polyester and epoxy powder coat options in any RAL colour, with gloss, satin, or matte textures available. This gives customers flexibility to match appearance, durability, and application requirements. Polyester powders are often selected where UV stability matters, while epoxy systems can be useful for specific performance needs. Finish selection is typically based on the part's environment, appearance goals, and end-use demands.

Surface preparation is one of the most important steps in achieving a durable coating. Marcus prepares parts through degreasing, acid cleaning, and zinc phosphate pretreatment before powder is applied. This process helps remove contaminants, improve coating adhesion, and support long-term corrosion resistance. Proper pretreatment is especially important for automotive components, where finish failure can begin if oils, oxidation, or residues remain on the surface.

Powder coating is often preferred for automotive metal parts when durability, impact resistance, and corrosion protection are priorities. It can provide a more robust finish than conventional wet paint, especially on components exposed to handling, road debris, or outdoor conditions. Marcus also offers other finishing processes, but powder coating is a strong choice when customers want a uniform, hard-wearing finish with texture and colour flexibility.

Marcus validates powder-coated parts through ASTM B117 salt spray testing, inline dry film thickness monitoring, and full batch certification. These checks help confirm coating consistency, corrosion resistance, and process control across production runs. Testing is important for automotive applications because finish performance affects both appearance and part protection. Documented quality checks also support traceability and confidence for OEM and industrial supply requirements.

Yes. Marcus operates an in-house powder coating facility as part of a broader manufacturing operation that includes die casting, CNC machining, tooling, and assembly support. That setup is well suited for customers who need repeatable production quality, coordinated finishing, and a single-source supply partner. Certified systems including IATF 16949:2016 and ISO 9001 further support structured quality control for automotive manufacturing programmes.
