Many customers often ask us what the function of a row of holes in the fork is. Is it intended to be the special mark of the fork? Actually, this is the electrophoretic hole we cut on the fork to facilitate the flow of the electrophoretic fluid inside the fork.

Electrophoresis is one of the most effective methods for coating metal workpieces. Electrophoretic painting is to have been painted on the conductivity of the material in the full of water to dilute the concentration of low electrophoretic coating as anode or cathode in the tank, the other set in the tank and its corresponding cathode (or anode), in the indirect communication between dc after a period of time, in the coated surface sedimentary out even close, not dissolved by water coating method of a kind of special coating.

Electrophoretic hole is marked

in red circle as shown above.

Electrophoresis primer for cutting fork platform and guardrail

Main advantages of electrophoretic primers over other primers:

The electrophoretic coating has high permeability and can permeate into the interior and gap of the coating.

The paint film is uniform, fine and tight.

Strong corrosion resistance;

High hardness, impact and wear resistance;

Corrosion and color resistance, aging resistance;

The low solvent content of electrophoretic coatings is beneficial to environmental protection and production safety.

Most of the structural parts of the cutting fork, small parts of the arm car and thin plate parts are made of electrophoretic primer, which greatly improves the corrosion resistance and rust resistance of the structural parts and maximizes the safety and service life of your equipment.
