Excessive wear of the extrusion cylinder and extrusion pad, improper fit of the extrusion cylinder and extrusion pad, and the difference in the diameter of the gasket used exceeds the allowable value;
Before welding, we should do some simple liquidation work to remove some oxide films and mistakes on the weld or the surface of the welding wire. We can use chemical cleaning methods. This method has a high rate and stable quality. It can be used to clear the welding wire and workpieces that are not large in size and are consumed in batches. It can be dipped and scrubbed.
Aluminum tube is a kind of non-ferrous metal tube, which refers to a metal tubular material that is made of pure aluminum or aluminum alloy by extrusion processing to be hollow along its full length in the longitudinal direction.
The interior of the painting room is required to be clean and clean, to achieve dust-proof, insect-proof and certain ventilation functions to ensure that the surface quality of the aluminum plate is not polluted. At the same time, the process conditions are changed in time because of the temperature change.
profil aluminum supplier china needs to be cooled after being extruded by a die, in order to improve the mechanical and physical properties of the material. Coolant needs to be used in the cooling process, and different materials have different effects. Common ones are water or oil-based coolants. If water is used for cooling or the proportion of copper in the cooling liquid is too much, it is easy to cause yellowing of the surface of the profile. The reason is that aluminum is an active chemical metal element, and it is prone to chemical reactions when it comes in contact with materials in the air and water.
