Warm extruding, or forging, is done on billets brought to temperature ranges between 800 and 1800 degrees F. Hot extrusions are performed on aluminum which has been fully plasticized by heat and is often performed in a vacuum to avoid oxidation. After an aluminum profile has been extruded, it is straightened by a stretcher.
 electrophoretic coating high rate of lysis in the water completely dissolved or emulsified, prepared into the bath viscosity is very low, it is easy to penetrate into the bag-like structure and the gap, especially for the special-shaped conductive material surface coating Installed.
