We all know that the composition of die-cast aluminum is different from that of profile aluminum. Therefore, the surface treatment methods of die-cast aluminum alloy and profile aluminum will also be different, which often leads to the difficulty of determining the surface treatment method of die-cast aluminum alloy or it is impossible to determine directly Today, Bengbu Longhua Die Casting Machine will introduce some die-casting aluminum alloy surface treatment methods to everyone, hoping to have inspiration for everyone.
There are many kinds of surface treatment methods for die-casting aluminum. Which process method is used to treat die-casting aluminum alloy depends on the quality requirements of the product. Currently, there are more common surface treatment methods:
1, if the surface quality requires an aluminum alloy metal color, you can use polishing or passivation anti-corrosion protection treatment process;
2, if the surface does not require the true color of the aluminum alloy metal, a cleaning or passivation anti-corrosion protection treatment process can be used;
3, if the surface needs various decorative effect colors, it can be treated by cleaning, passivation, painting or electrophoresis;
4, if the surface must be protected by plating metal, cleaning and plating can be used;
5, if the product requires high corrosion resistance, you can use cleaning, activation, passivation treatment, or passivation treatment by sealing and spraying treatment;
6. At present, in the industry of aluminum die-casting treatment, metal conductive oxidation treatment is also used. Now, basically using the above six die-casting aluminum surface treatment methods, I believe that with the development of technology, there will be more and more die-casting aluminum surface treatment methods.
