The Importance of Automotive Castings in Automotive Industry

Process involved in producing automotive parts using die casting

Hot Chamber Die Casting : In this technique, a gooseneck machine uses a built-in furnace to heat the metal until it melts. A hydraulically powered piston uses a nozzle and gooseneck to push the molten metal out of the furnace into the die chamber. The molten metal is then held under pressure in the die cavity until solidified. Die casting involves heating a metal until it melts, then forcing that liquid metal into the shape of a mold. It has a characteristic melting point. It works best with metals with low melting points, such as zinc or magnesium; aluminum is unsuitable for this process because of its high melting point.

Cold Chamber Die Casting : To fill a die cavity with molten metal, an operator pours the metal into a shot sleeve placed over the injection cylinder. The plunger forces the molten metal into the die cavity without heating the sleeve. Cold chamber die casting uses pressures of 30 MPa to 150 MPa. This process uses high melting point aluminum alloys. Cold chamber die casting is a successful method of producing automotive components. The process results in dense metal castings and stronger automotive parts. It's easy to perform, requires less maintenance than other processes, and has excellent dimensional accuracy.

The Development Trend of Automobile Castings and Its Manufacturing Technology

Casting is one of the oldest metal forming methods. Approximately 15% to 20% of auto parts are castings produced by different casting methods. These castings are mainly key components of the power system and important structural components. At present, the production technology of automobile castings in developed countries in the European and American automobile industries is advanced, with good product quality, high production efficiency and low environmental pollution. Casting raw and auxiliary materials have been serialized and standardized, and the entire production process has been mechanized, automated, and intelligent. These countries generally use digital technology to improve the level of casting process design. The casting rejection rate is about 2% to 5%, and a transnational service system has been established and network technical support has been implemented. In contrast, although the output of automobile castings in my country is relatively large, most of them are black castings with relatively low added value and technical content, and relatively simple structure, which is far from the foreign level. This article mainly discusses the development direction of automobile castings and automobile technology from the development needs of automobile energy saving and environmental protection.

Integrated Design Of Automobile Castings　
With the increasing requirements for energy conservation and environmental protection of automobiles and reduction of production costs, we will make full use of the advantages of casting to realize the casting of integrated parts through reasonable design and structural optimization of several parts formed by stamping, welding, forging and casting. Forming can effectively reduce the weight of parts and reduce unnecessary processing processes, thereby achieving lightweight and high-performance parts.　

The development trend of integration of automobile castings is more obvious in the development of non-ferrous alloy castings. In order to make full use of the characteristics of the casting process that can achieve the production of complex structure castings, integrated design of high-pressure castings such as door inner panels, seat frames, instrument panel frames, front-end frames and firewalls have emerged. The dimensions are significantly larger than those currently produced. For castings, a die casting machine with a tonnage of 4 000 to 5 000 tons or even greater is required for production.

Lightweight Of Automobile Castings
On the premise of ensuring the strength and safety of the car, reduce the curb weight of the car as much as possible to achieve light weight, thereby improving the power of the car, reducing fuel consumption, and reducing exhaust pollution. For every 100 kg reduction in vehicle kerb weight, fuel consumption per 100 kilometers can be reduced by 0.3 to 0.6 L. If the vehicle weight is reduced by 10%, fuel efficiency can be increased by 6% to 8%. With the need for environmental protection and energy saving, the lightweight of automobiles has become the trend of the world's automobile development, and the lightweight of automobile castings has also become one of the important development directions of automobile castings.　

High Performance Of Automotive Casting Materials　
Improving the performance of the material, so that the unit weight of the part can withstand higher loads, is one of the methods to effectively reduce the weight of the casting. Bracket type structural castings account for a large proportion of automobile castings, so the development of its castings has become one of the focuses of attention. Through heat treatment and other measures, the microstructure of the material is changed, thereby improving the strength, rigidity or toughness of the parts, which can effectively reduce the weight of the parts.　

Austempered ductile iron not only has higher strength than ordinary cast steel materials, but also has a lower density than steel. Its density is 7.1 g/cm3, while the density of cast steel is 7.8 g/cm3, which is a widely recommended material in recent years. . It adopts austempered ductile iron, which is 10% lighter than steel castings under the same size of castings. Dongfeng Motor Corporation has carried out a lightweight verification work on a certain type of commercial vehicle using austempered ductile iron instead of steel castings. In view of the high strength characteristics of austempered ductile iron parts, 14 suspension parts were redesigned in the expert forum. Generally speaking, the material replacement of automobile castings often accompanies the lightweight design of the parts.　　

Different Types of Casting Wheels

When it comes to casting wheels, there are two main types: gravity casting and low pressure cast wheels. Let's look at the differences between them.

Low-Pressure Casting
Low pressure casting wheels is a type of die-casting process that uses the force of pressure to fill the mold with molten metal. This method is commonly used for producing smaller, lighter parts and wheels due to its ability to create more intricate shapes than gravity casting.

The process involves injecting molten metal into a heated chamber at low pressures, which allows it to flow into an open mold below under precise control. Low-pressure casting makes use of external pressure and vacuum systems in order to achieve accurate results, making it well-suited for complex designs where precision and detail are essential.

Additionally, this type of casting offers greater strength and durability compared to other types of casting methods as the high pressure ensures that all air pockets and voids are eliminated from the finished product.

Gravity Casting
Gravity casting wheels is a type of die-casting process that uses the force of gravity to fill the mold with molten metal. It is typically used to create large wheels and parts, such as those found in automotive applications.

In this method, the molten metal is poured into a heated chamber where it falls into an open mold below due to gravitational forces. This allows for more precise shapes and better control over the finished product's dimensions compared to other casting processes.

The advantage of this method lies in its simplicity – no external pressure or vacuum system needs to be employed in order to achieve accurate results.

Additionally, it offers greater flexibility when creating complex designs since there are fewer restrictions on what can be achieved with gravity casting than with other types of casting methods.

Advantages of Casting Wheels

Casting wheels offer a range of advantages compared to other types of wheels and can be an ideal option for vehicles that require greater performance.
