Market analysis and application of mold industry
1.Current status and prospects of die casting market
(1) Market size
Demand for die casting continues to grow. The global die casting market size is US$84.9 billion in 2023 and is expected to reach US$139.95 billion by 2031, with a compound annual growth rate of 6.54% from 2024 to 2031.
(2) Market prospects
Die casting is widely used in many industries, among which the demand in the automotive industry is particularly significant. Aluminum alloy has become one of the ideal materials for lightweighting automobiles with its moderate cost and excellent performance. It has high corrosion resistance, low density, good forming and cutting performance, significant weight reduction performance and cost-effectiveness. Energy conservation and emission reduction policies promote the development of light vehicles. The state strictly regulates the fuel consumption and emissions of fuel vehicles.
Lightweight technology can improve fuel efficiency, improve handling and safety, and increase comfort. The demand for lightweighting of new energy vehicles continues to grow. Although the three-electric system and intelligent equipment make the vehicle heavier, lighter weight can increase the cruising range. At present, the application of aluminum alloys in parts such as new energy vehicle body structures has growth opportunities and market potential. With the deepening of the application of aluminum alloys in the automotive industry, the penetration rate of aluminum automotive parts will increase and the market size will continue to expand.
2.Introduction to die casting process
Die casting is an automated process of pressing molten alloy into a mold under high pressure and high speed. Once the alloy is heated to a high temperature and melted, it is injected into the mold under high pressure. The morphology is divided into two halves, one is static and the other is movable. After the molten metal is injected and solidified, the casting has an accurate shape and a smooth surface. A set of molds can be used multiple times and is suitable for mass casting.
3.Industries using die casting
