Die-casting aluminum and automobile lightweight

Die-casting aluminum and automobile lightweight

1. "Fuel saving and emission reduction" has spawned more lightweight demand

Under the background of the "carbon peak, carbon neutral" strategy, the automobile industry has ushered in the most stringent fuel consumption and emission standards in history. According to the data, for every 100kg reduction in vehicle curb weight, fuel consumption per 100 kilometers can be reduced by 0.3-0.6L. Strict fuel consumption and emission standards will lead to a huge lightweight application market.

2. The penetration rate of new energy vehicles continues to increase, and the lightweight accelerates

Aluminum alloy is the most commonly used lightweight material for automobiles, and the number of bicycles will continue to increase in the future. At present, mainstream automotive lightweight materials include high-strength steel, aluminum alloy, magnesium alloy and carbon fiber. Among them, aluminum alloy has the characteristics of light weight, high tensile strength, good recyclability, corrosion resistance, strong plasticity, and relatively mature technology. The material density It is significantly lower than high-strength steel, and its cost and process difficulty are better than magnesium alloy and carbon fiber. It is the most cost-effective and feasible lightweight material under the current technology. At present, aluminum alloys have been widely used in steering knuckles, control arms, subframes, motor housings, battery boxes, braking systems, wiper motors and other auto parts. It is expected that under the general trend of automobile lightweight, more aluminum alloy parts Components will replace traditional steel components, and the amount of aluminum alloy used in bicycles continues to increase.

Aluminum alloy parts will replace traditional steel parts, and the amount of aluminum alloy used in bicycles continues to increase.

3. Integrated die-casting technology makes the all-aluminum body more cost-effective

Die-casting technology is a special casting technology. At present, die-casting aluminum alloy products account for about 54% to 70% of the aluminum used in automobiles. Integrated die-casting technology is a new revolution in die-casting technology. By redesigning multiple independent parts that need to be assembled in the original design, and using a super-large die-casting machine for one-time die-casting, complete parts can be directly obtained to realize the original functions.

4. Application advantages of integrated die-casting technology

Precision die-casting processing is one of the most used metal product manufacturing processes at present. Precision die-casting parts have good bearing capacity, high dimensional accuracy and smooth surface. Therefore, precision die-casting processing is widely used in automobile manufacturing, mechanical parts processing, hardware tools, Toys, decorations and other industries.

5. The integrated die-casting market has a huge space

The automobile industry is an important downstream customer of the die casting industry. With the increasingly high requirements for lightweight automobiles, aluminum alloy castings are gradually replacing gray iron castings, and the demand for aluminum alloy die castings continues to increase. With the rapid development of the global die-casting industry, the demand for aluminum alloy die-casting parts in all walks of life is also increasing, and the development prospect of the die-casting machine industry is very broad.
