Die casting surface treatment process detailed
First, die casting surface treatment needs
With the continuous development of industrial production, die casting as an important component is more and more widely used in various fields. However, the surface of die-casting parts often has imperfect situations such as pores, inclusions, and shrinkage holes, which not only affects its appearance, but also reduces its material properties and service life. Therefore, it is very necessary to treat the surface of the die casting.
Second, commonly used die casting surface treatment process
1. Electroplating
Electroplating is a process in which a metal is plated on the surface of a device by electrolysis of the electrodes and the use of ions to deposit the metal. Common die casting electroplating
Art has chrome plating, zinc plating, silver plating and so on. The surface after electroplating is not only beautiful, but also has excellent corrosion resistance and hardness.
2. Spray
Spraying is the process of spraying paint on the surface of the device, which is suitable for die casting parts of various materials, including aluminum and zinc alloys. Common spraying materials are paint, powder,coating, resin, etc., the surface after spray treatment has good anti-corrosion, anti-oxidation and other properties, but also can change the color and texture of the device surface.
3. Anodizing
Anodizing is to place the metal product in an appropriate solution and use its own characteristics of anodizing potential to oxidize its surface to form an oxide film
Art. Common anodizing materials are aluminum, magnesium, zinc and other alloys. The anodized surface has good corrosion resistance, wear resistance and electrical conductivity.It can also change the color and gloss of the device surface.
Third, the choice of die casting surface treatment process
When choosing the surface treatment process of die casting parts, it is necessary to consider a variety of factors, such as materials, costs, and the use environment. In general, steel, copper and other metal materials are more suitable for electroplating treatment, while lightweight alloy materials are commonly sprayed or anodized. At the same time, under the premise of ensuring product quality, it is also the consensus of the industry to control costs as much as possible.
