Die-casting mold is a kind of mold. With the rapid development of automobile and motorcycle industry in China, the Die Casting industry has ushered in a new period of development. Meanwhile, higher requirements have been put forward for the comprehensive mechanical properties and life of die casting molds.Secretary general of the international mold association,it is still difficult to meet the requirements of continuous improvement of service performance only relying on the application of new mold materials,and various surface treatment technologies must be applied to surface treatment of die casting molds to meet the requirements of high efficiency,high precision and high life of die casting molds.

The first is to comply with the transfer of international industrial chains and grasp the opportunity for development. From the mid-1980s to the 1990s, the world's shipbuilding and ship-repairing industry completed its transfer to East Asia. By the beginning of this century, East Asia had accounted for more than 80% of the world's shipbuilding market share, of which Korea and Japan accounted for 30% to 35%, and China accounted for 8% to 10%. China’s shipbuilding industry produced 4.6 million tons in 2003, 8.4 million tons in 2004, and 10 million tons in 2005. It is expected to reach more than 20 million tons in 2010, and catch up or surpass South Korea and Japan to become the world's largest shipbuilding nation. The corresponding production of marine coatings has also shifted to East Asia, especially to China. In the early 1990s, after the international coating IP was settled in Shanghai, in recent years, the world’s major ship coating multinationals such as Jordan, Hemple, Sigma, Kansai Kansai, Nippon, Kcc, Ameron, ICI, etc. all landed in the Yangtze River Delta and the Pearl River Delta. In the region, a production capacity of over 200,000 tons/year has been formed. If China considers the use of paint for ship repair every year, the total capacity of the marine paint market will reach 300,000 to 350,000 tons/year by 2010, and multinational companies will expand their production capacity in China.
The second is the construction of infrastructure to promote the development of heavy anti-corrosion coatings. For more than a decade, China’s expressways have grown from zero to the second largest country in the world, and railway construction has grown at an annual rate of more than 10%. The heavy anti-corrosion systems of the bridges (steel structures and concrete) and highway guardrail facilities that are provided with them have made considerable progress; the corresponding bridge industry standards have also been revised, and both the paint system and product performance are required to be gradually in line with international standards; The installation standards began to introduce environmentally-friendly waterborne coating systems. For example, the heavy-duty anti-corrosion system adopted by the Hangzhou Bay Bridge reflects today's international standards. At the same time, there are thousands of kilometers of bridges in our country that have entered the repainting maintenance period. Urban infrastructure such as overpasses, light rail, subways, water and gas pipelines, and large venues, especially those for the 2008 Olympics, the 2010 Shanghai World Expo and the Guangzhou Asian Games, all require high-quality, high-performance, and environmentally-friendly heavy-duty materials. Coating system.
The third is the "world manufacturing base" to promote the rapid growth of China's floor coatings. The construction of industrial parks and general factory buildings has promoted the development of epoxy industrial floors at a rate of 30% to 40% in recent years, becoming one of the highlights of the coatings industry. In addition to general-purpose epoxy floor, functional industrial floor - conductive, non-slip, chemical resistant floor is developing.
Fourth, the concept of the overall solution for paint coating has become increasingly popular, promoting the development of coatings and product upgrades. Since the 1980s, ship painting has promoted the pretreatment of steel plates with inorganic zinc-rich pretreatment, which has promoted the upgrading of shop primers. In recent years, in order to reduce the coating cost and the cost of sandblasting the substrate, a low-treatment surface universal primer has emerged; wet blasting and high pressure water derusting have spawned the development of wet rust surface primers, new paints. At the same time, the assembly process puts forward higher requirements on the coating performance and promotes the improvement of the performance of heavy-duty coatings.
Fifth, environmental protection regulations promote new product development and progress. The Organic VOC Regulations and HAPS (Hazardous Air Pollutants Emissions Regulations) promote the development of heavy-duty coatings in the direction of high solids, solvent-free, and water-based. Although traditional low solid content anticorrosive coatings still account for more than half of the market in China, and it is difficult to completely withdraw from the market in a considerable period of time, environmental protection coatings will surely become mainstream in the high-end market and coastal economically developed regions. In the early 90s of last century, the Ministry of Public Security issued mandatory regulations for coating steel structure fire-retardant coatings and related coating standards, which promoted the development of fire-retardant coatings and quickly promoted the use in China, although there are currently irregular regulations and applications. , imperfections, but the direction of its development is good.
In addition, the research, development and exchange of multi-disciplinary heavy-duty anti-corrosion coatings are unprecedentedly active. Multinational corporations have gradually shifted their R&D centers to China. Research institutes and universities have become more involved in the field of heavy anti-corrosion, injecting new technologies into the development of new materials and technologies. vitality.
Five factors to promote the development of heavy anti-corrosion coatings
From the late 1980s until now, China's heavy-duty coatings and coating industries have entered a golden period of rapid growth under the impetus of rapid economic development, becoming the fastest growing paint industry, the earliest international integration, and the largest market share of industrial coatings. field. So, what drives the development of heavy-duty coatings? The author thinks that there are the following reasons:
