Lubricated extrusion () can greatly reduce the extrusion pressure, improving the speed and improve organizational performance extrusion products. Some people think that, because of the aluminum mold surface sticky layer of iron particles react with high-temperature aluminum oxide on the surface of aluminum oxide which is generated, which can then stick by its effective set of metal flow in aluminum extrusion machine prices three more formed of aluminum oxide. Therefore, ferric oxide is a cause mold sticky aluminum. From this point of view can be fully explained in lubrication squeeze (), the lubricious coating can prevent direct contact with the aluminum mold, tool and die to reduce the role of surface oxidation, which played a sticking friction reduction, improved products surface quality of the effect.
