Our Services

Ameya Finishing provides one of the largest CED coating facility in Pune and is a reliable partner when it comes to all your requirements for CED (Cathodic Electro Deposition) related services.

Our well equipped two facilities that fulfil all coating requirements you may have.

The advantages of CED over Powder Coating are:
  • You get Uniform DFT all over the component.
  • You get coating all over the part (inside the Box section and outside the box section) so probability of getting rusty, minimizes
  • You get a minimum 1000 hrs of SST life over 240-600 hrs in powder coating
Ameya Finishing Solutions was set up in 2014 with its members having more than 20 years of experience in this industry and with experienced manpower in this field. It boasts of being one of the largest CED coating facilities in Pune district.

Manpower is our primary asset. We have trained, educated, and experienced technicians on the floor who ensure top-most quality at all times.

CED is Effective

In a study done by researchers from the University of Belgrade*, the researchers found that the model of organic film growth on a cathode during the process of electrodeposition corresponds to a great extent to the real process of cathodic electrodeposition of an epoxy coating on steel and shows good agreement with the experimental results.

The important parameters for the success of this process are:
  • The film thickness
  • The rate constants on the applied voltage, bath temperature and resin concentration in the electrodeposition bath
The deposition parameters have been known to have a great effect on the cathodic electrodeposition process and the protective properties of the coatings.

The study suggests that electrolyte penetration through an organic coating occurs in two steps.
  1. The first step is related to water uptake, when molecules of pure water diffuse into the micropores of the polymer net according to Fick’s law and is independent of the type and dimensions of the ions in the corrosive electrolyte.
  2. The second step is related to the penetration of water and ions through the macropores, which leads to contact between the electrolyte and the metal surface and the beginning of electrochemical processes at the metallic interface.
The researchers did statistical analysis of the different layers of the coating through its thickness using optical microscopy and image analysis. This enabled the pore number, pore size distribution, mean pore diameter, mean pore area and mean percentage of the surface covered by pores to be determined.

These results provide the shape and dimensions of the macropores through the coating. Knowing the number of the pores in each layer can help calculate the quantity of electrolyte inside the macropores.

The study concludes that conduction through the coating depends only on conduction through the macropores, although the quantity of electrolyte in the micropores of the polymer net is about one order of magnitude greater than that inside the conducting macropores.
