Chi Nano Science and Technology Division PVD coated titanium plant firmly believe that "the development of production quality and the competitiveness of the first" business philosophy. The center together with the well-known, more competitive company PVD coated nano-functional production process, focus on the development of a series of significant improvements in industrial productivity of the nano-mold film PVD coating system, and strive to achieve the critical economic situation breakthroughs.

Nano-PVD coating technology is a range of materials science, physics, electronics, chemistry, environmental science and other new social technologies. Core technologies used in metal processing, manufacturing, etc., which aims to promote modern cutting tools and the rapid development of manufacturing and processing industries.

Die-casting mold In the die casting industry since the beginning of each casting cycle, the mold cavity hot molten alloy to withstand acute thermal effect, the work surface will have a compression heat stress; die-casting in the mold after the end of spray lubricant, to quench, which has on its surface tensile stress. In this alternating thermal stress, the mold surface will produce thermal fatigue micro-cracks, with the increase in the number of die-casting cycle, the rapid expansion of micro-cracks, and some extensions to the Ministry of the heart, the formation of crack turtle. If there are cracks around the molten alloy is accompanied by erosion and corrosion of the mold cavity, the mold surface will be further damaged, eventually leading to cracking or even die early retirement. Stick die casting process, erosion, corrosion caused by the product rejection rate, low productivity, and even damage caused by mold and other issues has been troubled by the casting company's long-standing problem.

Therefore, taking into account the large volume, low-cost, efficient production of alloy die castings, while reducing maintenance time to be mold, Ch
