Cataphoresis and anaphoresis – electrophoretic coating methods

In-house design and engineering

Cataphoresis – high-tech dipping coating method

Cataphoresis or electrophoretic coating in general is the most high-tech, economical and highly ecological way of coating. It is used as a surface treatment of metal products, especially for steel, galvanized and aluminium parts. We provide complete industrial lines for:

  • Cataphoretic coating;
  • Anaphoretic coating;
  • Rebuilding of anaphoretic lines to cataphoretic lines.

Cataphoresis – Why choose cataphoretic coating of metals

Currently, cataphoretic coating is technologically the most advanced method of anticorrosive surface treatment for metal products.

Cataphoretic coating is mainly used as a base layer, followed by other surface treatments (dipping or powder coating). However, it is also often used as final, single-layer, painting. The use of cataphoretic coating guarantees a significant increase in the corrosion resistance and utility properties of the products, which are significantly increasing its application on the market.

The benefits of cataphoresis from MEGA–TEC

  • High corrosion resistance even at low paint thickness;
  • Very good zabíhavost – cavity protection;
  • Uniform coating thickness over the entire surface including hard to reach places;
  • No drops or irregularities in the applied paint layer;
  • Constant reproducibility;
  • Low demands on operating personnel – automatic coating process;
  • High paint yield over 99% – economical closed circuit;
  • Fast coating process (180–240 sec.);
  • Eco-friendly operation – minimum emissions, wastewater, solid waste and minimum solvent content;
  • Safety – no special safety measures required.
Customized cataphoresis lines

Customized cataphoresis lines

Industrial lines for cataphoretic coating are designed according to customer requirements and needs. The lines are constructed depending on the type of assortment and with regard to the batch production of coated parts. The final concept of cataphoresis is always chosen according to the economic advantage for the customer.

The pressure on corrosion resistance combined with the advantages of the highly economical surface treatment process together with the environmentally friendly operation has made cataphoretic coating an important technology, especially for the automotive industry. However, this technology soon spread to other fields of engineering and consumer industry.

Anaphoretic coating & conversion to cataphoretic lines

Anaphoretic coating & conversion to cataphoretic lines

We also provide anaphoretic lines for our customers. Due to the current trends in surface treatment, we are also rebuilding anaphoretic lines to more state-of-the-art cataphoretic lines.

Our case studies

BWI GROUP complete EC line

BWI GROUP

Complete EC line

In 2016 MEGA-TEC has supplied a ccomplete EC line for the czech subsidiary of BWI GROUP. The tact line also includes afterburner and neutralization station and is used for industrial coating of autmotive shock absorbers.

The step by step line with pretreatment and electrocoating bath uses a "Walking beam" conveyor above each technological section. During a single tact all suspensions change their position while retaining variable function times of each operation.

Line parameters
Suspension dimensions: 1700 × 900 × 1300 mm (L × W × H)
Suspension weight: 350 kg, line tact 200 s

We care about you

MEGA–TEC saves your money.
Get all the care you need.

MEGA Care reduces downtimes to the necessary technological minimum by active monitoring, prevention and remote adjustments in advance. Periodical inspections at the point of installation provide three days of exhaustive evaluation during regular production, membrane samples are sent to MEGA laboratory for testing to show early signs of scaling or fouling. Inspections to gather hands-on data together with overall parameters monitoring bring necessary information to ensure reliable performance.
