Die-casting molds ion coating technology

In the die-casting industry, the high product scrap rate, low production efficiency, and even mold damage caused by mold sticking, erosion, and corrosion during the die-casting process have always been a long-standing problem that has plagued die-casting companies.
Now modern surface engineering technology is applied to the surface treatment of die-casting molds, which greatly improves the surface performance of die-casting molds. It is long-lasting and solves problems that traditional processes cannot solve. In the words of insiders, it has pioneered the surface treatment of die-casting molds.
This method is to use ion coating technology to deposit a layer of metal ceramic film on the surface of the mold. This film has the functions of wear resistance and corrosion resistance. Since the material used in this film is not affinity or reaction with metal solutions such as aluminum and zinc, it can greatly improve the mold release performance of the die-casting without sticking. For example, a certain manufacturer has an aluminum alloy die-casting with very high product quality requirements. Due to the sticking phenomenon, the mold has to be polished once every hour of pressing. After surface treatment, the mold is not removed until eight hours later, and it is very easy to clean.
In zinc alloy die-casting, since the zinc alloy solution can easily react with the mold steel, some molds will be corroded during the mold trial stage. After the mold is surface treated, since the zinc alloy solution does not come into direct contact with the mold, this situation is completely eliminated, thus extending the service life of the mold and improving production efficiency and product quality.
