How about the finished of rapid prototyping CNC aluminum parts(CNC machining aluminum alloy)


Aluminum of rapid prototyping after CNC processing, need to go through a series of surface treatment, so as to get a bright and good surface.
So what is the surface treatment effect of aluminum alloy rapid prototyping in the end?


1, sandblasting: the main role is to clean the surface, before sandblasting can increase the surface roughness, it is good to improve the adhesion, sandblasting has coarse sand fine sand, commonly used 120 mesh and 100 purposes.
2, conductive oxidation: aluminum parts conductive oxidation has a certain corrosion resistance and conductivity, electronic equipment with more rapid prototyping, aluminum conductive oxidation can prevent the interference of electromagnetic signals.
3, anodizing: anodizing treatment method is the use of the principle of electrolysis, forming a layer of oxide film on the surface of the hand plate, in order to increase the ability to resist corrosion and make the appearance of beautiful method.
4, spray: also known as electrostatic powder spraying, the advantages of the technology is reflected in advanced technology, energy saving and efficient, safe and reliable, bright color and other aspects.
Its working principle is to charge the plastic powder through the high voltage electrostatic equipment, under the action of the electric field, the coating will be sprayed to the surface of the Parts, the powder will be uniformly adsorbed on the surface of the Parts, forming a powdery coating.
5, electroplating: the Parts as the cathode, the formation of the coating material as the anode, put both in the bath bath in the tank, and then through direct current or AC and DC, the formation of the coating material ionization and from the bath to the surface of the Parts, firmly attached to the formation of different thickness of the coating method.
Aluminum alloy handboard with more is anodic oxidation (mostly natural oxidation), spray (rich color, cheap and good quality, with the most), electrophoresis (mainly is the bright K gold, K silver, champagne color), thermal transfer (mainly wood grain transfer printing, showing wood texture, beautiful).

The surface treatment of aluminum alloy rapid prototyping is finally to enhance the surface hardness and wear resistance of aluminum alloy, expand its application scope, prolong the service life, surface treatment has become an indispensable link in the use of aluminum alloy, and anodic oxidation is the most common application of aluminum alloy rapid prototyping.
