Die casting surface treatment technology is of great significance for improving product performance and prolonging service life. In recent years, with the continuous progress of science and technology, the surface treatment technology of die casting has also made remarkable research progress.

On the one hand, traditional surface treatment technologies such as spraying and electroplating have been further optimized and improved. The application of new coatings and electroplating materials makes the surface of die-casting parts have better corrosion resistance, wear resistance and decoration. At the same time, the control of the spraying and plating process is more precise, enabling more uniform coating thickness and higher adhesion.

On the other hand, emerging surface treatment technologies such as laser treatment and micro-arc oxidation also bring new possibilities for die casting surface treatment. Laser treatment technology can improve the microstructure and properties of die casting parts by micromachining the surface with high energy laser beam. The micro-arc oxidation technology can form a dense and hard oxide film on the surface of the die casting, and improve the hardness and wear resistance of the surface.

In addition, some comprehensive surface treatment technologies have also been studied and applied. For example, the combination of various technologies such as spraying, electroplating and laser treatment to form a composite surface treatment process can give full play to the advantages of various technologies to further improve the performance of the die casting surface.

With the deepening of research and continuous innovation of technology, die-casting surface treatment technology will continue to make new breakthroughs and progress. In the future, we can expect more efficient, environmentally friendly and intelligent surface treatment technology to be applied to the production of die casting parts, providing strong support for improving product quality and competitiveness.
