Abstract
A method for manufacturing an electro-filter for separating a mixture of gas and oil drops including: at least one body including at least one oil/gas separation chamber, at least one emitter electrode, and at least one collector electrode made of an electrically-conductive plastic material. The manufacturing method includes at least the following steps: implementation of a first injection cycle having at least one step of injecting the collector electrode, implementation of an overmolding cycle having at least the following steps: displacement of the injected collector electrode into a second cavity of the same mold or into the cavity of another mold, overmolding at least the oil/gas separation chamber of the body at least on the collector electrode, with an electrically-insulating plastic material.
