Because of these characteristics, the surfaces of the components are dense and smooth; their dimensions are accurate; they have low processing costs; they have high production efficiency; and because of these characteristics, they are appropriate for mass production. When Junying manufactures components in China, it does so using the technology of zinc alloy die-casting. This is due to the fact that it is more cost-effective. In spite of the fact that the benefits described above are associated with the process of zinc alloy die-casting, the material itself is not very chemically stable, it oxidizes rapidly when it is exposed to air, and it suffers from a reduction in surface gloss because of these characteristics. 

These issues have surfaced due to the inability of the material to form crystalline structures, which is the root cause of the problem. Zinc alloy die-casting parts have poor chemical stability and easily dissolve in acids and alkalis when they are exposed to those chemicals. This is because zinc alloy has a high zinc content. It is for this reason that zinc alloy die-casting parts can no longer be utilized in the processes of die-casting. As a consequence of this, the plating solution would become contaminated, and as a consequence of this, the bonding force between the plating layer and the substrate would be altered.

1. an examination that does not bring about the production of any results

Before proceeding with zinc alloy die castings, the blanks need to be inspected, and any Junying parts that do not satisfy the requirements of the electroplating process should be chosen for elimination. This should be done before moving on to the next step. Before moving on to the next step, this should be finished up first. For example, the surface of the parts has bubbles, cracks, cold lines, pinholes, and obvious intergranular aluminum die casting parts segregation; it is difficult to level these imperfections using mechanical polishing, or leveling them will cause future problems with the quality of the electroplating layer. Additionally, there is obvious intergranular segregation. In addition to that, the intergranular segregations can be observed with very little difficulty. There are also other examples such as.

2. A typical step in the polishing process consists of beginning the grinding process on a grinding wheel that has butter polishing paste applied to it before continuing with the grinding. This particular kind of wheel is also known as a polishing wheel, which is a name that accurately describes the purpose for which it is utilized the vast majority of the time. The surface of the component that was obtained in these conditions appears to be relatively flat and smooth rather than having any rough grinding lines. Instead, the surface appears to have been obtained through a process that involves grinding. This not only lays a solid foundation for the polishing process that comes later, but it also plays a significant role in enhancing the overall decorative effect. Ultimately, this contributes significantly to the overall aesthetic value. At the end of the day, this makes a significant contribution to the attractiveness of the finished product. This is done in order to eliminate any minuscule remnants that may still be present after everything else has been cleaned up. When it comes to polishing, the very first thing that Junying needs to make sure that she does correctly is to apply the appropriate amount of polishing paste.

This is the most important thing that Junying needs to make sure that she does. In the event that this cannot be accomplished, it is recommended that two distinct processes of polishing be utilized rather than combining the two processes into a single one. The cloth wheel needs to be loosened up after the initial rough polishing, a small amount of white oil polishing paste and white powder needs to be applied, and then the cloth wheel needs to be lightly polished in an orderly manner one more time. The polishing paste can be removed from the surface of the component after it has been polished, which can be done after the component has been polished. This is an activity that needs to be finished up during the portion of the project that is referred to as the roughing phase. In the event that this concern is not addressed, the subsequent finishing process will be challenging to carry out. If the area is not protected from the grease, there is a good chance that it will become deeply embedded in the surface, which will make it very difficult to clean. If the surface is not protected from the grease, however, there is a good chance that it will not become deeply embedded.

On the other hand, there is a good chance that the grease will not become deeply embedded if the surface is not protected from it. When it comes to the process of grinding and polishing zinc alloy die castings, this is of the utmost significance.

When a component is polished, the polishing paste will invariably become embedded in various areas, including screw holes, slits, and other areas. This is an unavoidable side effect of the polishing process. During the polishing process, this is an inevitable and unavoidable side effect. Because of the nature of the situation, this is the case regardless of the method that is used to degrease the components, whether it be electrochemical degreasing zinc die castings, chemical degreasing, or organic solvents. This is the case because of the nature of the situation. Because this is the only method that can be used, the polishing paste can only be removed from these components by first cutting into them with a knife. This is the only option that is available. It is not possible to plate components that have already had polishing paste applied to their surface because the polishing paste would interfere with the plating process.

4. Removal of grease through the application of an organic solvent

Die castings made of zinc alloy cannot be degreased in an alkaline solution for an extended period of time without the casting suffering some form of damage. The second method that can be used and is available to be used is brushing on the gasoline, which is done in order to apply it. This method is also available to be used. If you want the best results, you shouldn't let the hair sit in water for a long period of time; rather, you should brush the hair or use equipment that produces ultrasonic waves.

5. Electrochemical degreasing takes a much shorter amount of time to achieve the same level of degreasing effect as compared to chemical degreasing, which requires a much longer amount of time to complete. This is because electrochemical degreasing uses electricity rather than chemicals. When compared to the amount of time that is necessary for electrochemical degreasing, the amount of time that is necessary for chemical degreasing is significantly longer.
