In the development of society today, it is indispensable to the use of aluminum alloy profile, aluminum extrusion profile
processed finished product surface scratch what elimination method?
Aluminum extrusion profile processing commonly such as aluminum radiator, automobile motor shell, etc. It is the use of extrusion molding process, that is, aluminum ingot and other raw materials in the furnace after melting, through the extruder extrusion mold flow molding, it can also extrude a variety of different sections of the profile.
Aluminum extrusion profile if there is longitudinal or lateral extrusion on the surface after processing, a scratch or a raised scratch at the corner of the product, or a scratch or scratch in loading, handling, etc. These are common surface defects in the aluminum extrusion profile extrusion process, it is mainly eliminated chemical and physical two methods:
1. Chemical method: Refers to the selection of chemical reagents to polish, briefly speaking is the selection of chemical reagents to corrosion a layer of aluminum surface, scratches because there is a sharp edge, corrosion speed, light scratches can be completely eliminated after chemical polishing, chemical polishing data appearance bright, beautiful.
2. Physical method: That is, mechanical grinding, sand blasting, wire drawing, etc., generally on the deeper scratches choose this method.
Usually the two methods together, aluminum appearance can achieve excellent decoration effect.
