Powder Coating
Automated powder system with controlled pretreatment, film build, and cure for appliance and automotive programs.
E-Coating
Nine-stage zinc-phosphate pretreatment with cathodic immersion. Corrosion and adhesion performance verified to OEM specs.
Powder Coating
Greenfield Finishing runs a powder coating operation built around controlled environments, automated application technology, and a complete multi-stage pretreatment system. The setup supports repeatable Class A finishes, efficient color management, and consistent adhesion across OEM production volumes.
Environmental Room
Temperature and humidity controlled Environmental Room conditions all materials before coating. This prevents contamination, stabilizes substrates, and supports Class A surface specifications. The line accommodates parts up to 72 inches in length.
Application System
Application areas utilize up to 10 reciprocating automatic guns, supported by manual spray operators for complex geometries. Interchangeable color modules enable fast color changes and optional material reclamation for efficient production.
Pretreatment
Pretreatment is performed in a stainless steel, six-stage wash system using Iron Phosphate and a Non-Chrome Sealer. This improves adhesion, enhances corrosion resistance, and reduces environmental impact while meeting OEM requirements.
E-Coating
Greenfield Finishing provides a high-volume E-Coat operation built around automated material handling, controlled pretreatment chemistry, and consistent epoxy application. The system is designed for efficiency, repeatability, and strong corrosion-resistant performance across large batch runs.
Automated Transfer
E-Coat is applied using fully automated slide-rail transfer systems that move multi-tier fixtures through each process stage. Fixtures travel in uniform, repeatable cycles through pretreatment, epoxy coating, rinsing, and curing, ensuring even coverage and stable throughput.
Pretreatment Stages
Lines incorporate nine stages of pretreatment chemistry, including Zinc Phosphate and a Non-Chrome Sealer. This sequence prepares the substrate for high-quality coating adhesion and long-term durability while maintaining environmentally conscious process control.
Epoxy Application
Greenfield Finishing applies PPG 8th Generation Epoxy, formulated for corrosion protection and consistent film build. The system is optimized for efficiently processing smaller part sizes at high volumes and competitive production costs.
