E-Coating is an immersion coating process used to apply a uniform, continuous film with high corrosion-resistant properties to metal components.
Following surface pre-treatment, the process can be incorporated as a primer coat in a multi-layer coating cycle or used as a topcoat, depending on the functional, protective and aesthetic requirements of the product.
E-coating is an industrial electrocoating process in which metal components are immersed in a water-based paint bath and subjected to an electric current. In this way, the paint is deposited evenly and precisely across the entire surface of the workpiece, ensuring uniform coverage even in the most hard-to-reach areas.
At Inver-Press, E-Coating is carried out using a state-of-the-art system, designed to deliver high technical performance, production reliability and environmental sustainability.
The process integrates pre-treatment and E-Coating, with constant monitoring of process parameters and high repeatability.
Complete removal of oils, greases, dust and surface contaminants resulting from mechanical processing.
Removal of chemical residues to prevent cross-contamination between the various stages of the process.
Removal of oxides, rust and impurities from the metal surface.
Preparation of the substrate to ensure uniform and controlled phosphating.
It improves paint adhesion and enhances corrosion protection.
Final surface protection prior to entering the e-coat bath.
Following pre-treatment, the components are dip-coated using the E-Coat process.
This process ensures complete and uniform coverage across the entire surface, including internal parts and hard-to-reach areas.
The E-Coating process is suitable for parts made from carbon steel, pressed sheet metal, welded components, metal fabrications and technical parts intended for subsequent finishing processes or for direct use in industrial environments.
E-Coat is a high-performance technological primer, suitable as a base for subsequent finishing treatments, including powder coating and liquid painting.
The uniformity of the film and the quality of the pre-treatment help to improve adhesion, the continuity of the protective system and the overall durability of the coating system.

The E-Coating process is supported by an in-house laboratory dedicated to the chemical analysis of the pre-treatment tanks and the monitoring of the characteristics of the applied coating.
The laboratory is equipped with the necessary instrumentation to carry out chemical titrations of the process solutions, aimed at controlling the main operating parameters of the pre-treatment tanks, including the concentration of active components, free and total acidity, and reagent balance.
Regular analytical monitoring ensures that the operating conditions of the baths remain stable, optimises the replenishment of chemicals and guarantees the repeatability of the treatment cycle.
The in-house laboratory also carries out checks on the E-Coat coating, including:
The laboratory also enables checks to be carried out on the conversion coating layer resulting from the pre-treatment, verifying the phosphate weight and the correct formation of the protective layer.
During the coating process, the main operating parameters of the E-Coat bath are monitored, including deposition voltage, current absorption and bath characteristics.
Finally, to assess the anti-corrosion performance of the treatment system, accelerated corrosion tests and salt spray tests are carried out at qualified external laboratories.
The combination of chemical control activities and coating inspections ensures process stability, production repeatability and consistent quality of the E-Coating treatment.
The entire E-Coating process is managed by monitoring key process parameters, with regular checks carried out during the pre-treatment, deposition and curing stages. This approach ensures operational stability, consistent production and a coating of consistent quality.
