The Future Development Trend of Die Casting

Die casting technology is the most important modern casting technology, which has many advantages compared to other casting methods: small volume and light weight of castings; Low cost; High efficiency. The die-casting industry in China started relatively late, but has developed rapidly. Since the 1990s, China's die-casting machinery has developed rapidly, and a certain scale of enterprises such as automobiles, mechanical equipment, and electronic appliances have been formed in China. With China's accession to the WTO, the demand for die-casting machines at home and abroad continues to increase, and domestic production and manufacturing equipment is also constantly improving and improving. Some large-scale die-casting machines with high production efficiency and automation have also begun to appear. At the same time, it also brings opportunities to the development of the entire world economy. Under the pressure of enormous potential and development opportunities in the future, China is launching challenges to world powers.

1. Developing towards high technology

China's automotive industry and automotive component die-casting industry have entered the world's advanced level, but the structure of mechanical equipment is still relatively backward, and many mechanical properties cannot meet the requirements of automotive lightweight in the automotive manufacturing process. Therefore, China is moving towards the direction of automotive lightweight. And China's mold manufacturing and die-casting industry is also moving towards a high-tech development path. At present, China is rapidly developing towards the mold and die-casting industry. In the coming years, the country will continue to maintain an annual growth rate of 20% and an average annual growth rate of around 20%. With the continuous improvement and development of the technological level of the mold industry and die-casting industry, the market potential of China's mold industry will be increasing. In addition, China will actively develop and utilize new energy, environmentally friendly energy, new materials and technologies, and further improve the layout and construction of China's manufacturing industry. In terms of electric energy, the transformation from hydropower to wind and solar power generation can be achieved; In terms of new materials, high-tech industries such as new functional materials, biopharmaceutical materials, and high-end instruments can be developed; In the field of new energy, solar power generation and air source heat pumps can be developed.

2. Developing towards market demand

At present, many enterprises in China are actively exploring the market, which also brings development opportunities to the ingot equipment manufacturing industry. In the production of automotive parts, manufacturers generally use software technologies such as CAD, CAE, computer-aided design, automatic control and automation, CAM, etc. to replace traditional handmade molds when selecting forging molds. The development and manufacturing of these molds is an important technological trend in the automotive manufacturing industry. Higher requirements have also been put forward for casting equipment. In order to meet market demand, some manufacturers have also put forward new requirements for die-casting equipment: reducing density, reducing mold hole size, increasing mold hole stroke, reducing pressure and cylinder power, improving wear resistance, and improving product performance. Due to the outdated mold design adopted by domestic enterprises compared to foreign enterprises, the use of hydraulic motor driven servo motors is currently one of the key technologies widely adopted both domestically and internationally. In the future, with the continuous development of technology, hydraulic motor driven servo motors will also be gradually adopted. At present, hydraulic motors are still the mainstay in the domestic market, and in the future, they will gradually develop towards other drive motors.

3. Developing towards automation improvement

Die-casting machines generally have a continuous and self controlled casting automatic pouring line. When the pouring volume decreases or when more castings are needed, automatic pouring can be carried out according to process parameters. With the development of hydraulic technology, some die-casting machines can achieve automated pouring with a high degree of automation. For example, a Japanese company has changed its die-casting production line to an automated die-casting system. In addition to the low pouring volume, there are other reasons: such as slow cooling speed; Or there are defects in the installation process of the die-casting machine. Therefore, foreign countries have gradually adopted fully automatic die-casting machines and pouring machines - high-efficiency production equipment to improve die-casting quality and production efficiency. This automated equipment not only greatly reduces the number of workers, but also has the advantages of automatically controlling the pouring amount, automatically tracking and detecting the mold status, and automatically adjusting the mold thickness during the production process, thereby greatly reducing production costs and process conversion time.
