E-Coating with superior protection, uniform coverage, and high corrosion resistance, ideal for OEMs operating under the most demanding standards.
Processes engineered for the automotive industry
- 2 lines configured for series production.
- Thickness control aligned with technical specification, within ±2 microns.
- Zinc phosphate pretreatment engineered to maximize corrosion resistance.
Precision and control at every stage of E-Coating
The process begins with surface preparation and zinc phosphate pretreatment, followed by immersion of the parts in a cathodic electrocoating bath, where the coating is deposited uniformly on the metal surface through direct current.
Bath stability is maintained through continuous monitoring of critical parameters such as pH, conductivity, voltage, and temperature, ensuring precise coating thickness and consistent batch-to-batch repeatability.
Parts then move through rinsing and ultrafiltration systems before undergoing controlled thermal curing, ensuring complete coating polymerization and superior corrosion resistance.
Our processes are optimized for high-volume production
The E-Coating system operates through an immersion process that provides uniform coverage across the entire part — including cavities and complex geometries — ensuring long-term corrosion protection.
Zinc phosphate pretreatment creates a chemical foundation that enhances coating adhesion and strengthens corrosion resistance in line with project requirements.
The operation integrates seamlessly into high-volume production environments, with continuous monitoring and recording of critical parameters to ensure process stability and technical compliance.
Focused on high-volume production through rack-hanging systems
The process line is selected according to the technical characteristics of each part — including dimensions, weight, geometry, and production volume — ensuring operational feasibility and process efficiency.
E-Coating is standardized and controlled through critical process parameters that are monitored and recorded in real time, ensuring repeatability, stability, and consistency across production batches.
Rack design, configuration, and maintenance are developed and managed in-house, ensuring proper conductivity, uniform coating distribution, and process efficiency.

Frequently Asked Questions
Service is a fundamental part of our work. Please don’t hesitate to contact us with any questions about our solutions.
-
What level of corrosion resistance can you achieve?
Performance is validated according to the client’s technical specification, reaching up to 1,000 hours in salt-spray tests when the project requires it. E-Coat is commonly used on components operating in non-visible or hard-to-reach areas, where coating uniformity is critical for long-term protection.
-
What film thicknesses do you offer?
Thickness is controlled according to the client’s technical specification, typically operating between 15 and 30 microns, with continuous monitoring of process parameters.
-
Which materials can be processed in the E-Coating line?
Metal components such as carbon steel, galvanized steel, cast iron, and certain aluminum alloys, subject to prior technical validation.
-
Does the E-Coating process comply with automotive industry approval requirements?
The system operates under a structured new project management process and has experience with approval requirements such as PPAP. All required documentation and process validations are completed before production release.
-
Can E-Coating be integrated with other coating systems?
Yes — bilayer systems can be integrated by applying powder coating on top of E-Coat when the project requires enhanced corrosion performance or a specific finish.
