China's die-casting industry in terms of production power, die-casting machine quality, and production skills is still relatively behind compared with advanced countries in terms of die-casting. However, China has certain advantages in terms of quantity and employment; There is ample space for large-scale development. The rapid pace of development in recent years has also provided the possibility for China to quickly approach and surpass the advanced world level. After the Southeast Asian countries experienced the 1997 financial crisis, the die-casting industry has also undergone certain changes. Mr. Jiang Yongzheng of the Hong Kong Productivity Promotion Bureau, based on the development and current status of the Southeast Asian die-casting industry, analyzed the connections between various industries and the die-casting industry and the impact of the economic situation on it. It is thought that the financial crisis has caused the output value of die castings in Southeast Asian countries to decline sharply. However, Southeast Asian countries have opened up new parts to attract foreign direct investment, or to make financial activities faster to recover the economy. These preferential policies have provided opportunities for economic growth, and have also brought about the recovery of the die-casting industry. The development of gravity casting technology for kneading and forging aluminum alloys is also the focus of this meeting. From the history of kneading skills in China, the development of kneading and forging equipment, the development of kneading and forging products, and the progress of the research on the skills of squeezing and kneading and forging in China, The current situation of kneading and forging in China is summarized. We have not only seen the results obtained by kneading the forging industry in China in recent years, but also the gaps in industrialization and use. I believe that to continue the kneading and forging of our country, we must strengthen the following three aspects:
① Vigorously expand the mall space for kneading forged products, and continue to develop new products with high quality and low price
② Renovate the skills of backward kneading and forging equipment to improve skill stability and output power;
③ Improve the skill level, improve the planning and processing level of molds, and develop supply potential for enterprises.
Magnesium alloy is an alloy material that has been paid more attention internationally in recent years. The research and development of magnesium alloys, especially the research on aluminum alloy low-pressure casting , kneading and forging, and semi-solid processing skills, have even blossomed. Mr. Jiang Yongzheng of the Hong Kong Productivity Promotion Bureau summarized and analyzed the rapid development of the magnesium die casting industry in Hong Kong and the Pearl River Delta region in recent years. It is speculated that magnesium die casting still has excellent development potential in this region. The reasons are primarily:
① After China's entry into the WTO, it has a high and stable economic development speed, which provides opportunities for the development of the magnesium die casting industry in Hong Kong and the Pearl River Delta region;
② This region is in an outstanding geographical position in Asia, which facilitates the global transportation of magnesium die-casting products.
③ The developed basic industries such as metal processing and mold manufacturing in the region have created conditions for the rapid adjustment of the structure of the magnesium die-casting industry and the reduction of costs;
④ The long history of die-casting and low operating cost have improved the competitiveness of the magnesium die-casting industry in this region.
2 In-depth development of magnesium alloys and their forming skills
In recent years, the research on magnesium alloys has mainly focused on the development of new alloys and new forming skills, with the intention of expanding the applicable scale of magnesium alloys. The poor heat resistance of magnesium alloys is one of the first questions that limit its use.
Improved heat resistance can expand the scale of use. For this reason, many countries around the world have carried out many research assignments. Now, the most basic way to improve the heat resistance of magnesium alloys is to add rare earth elements to the alloy.
