The Development of Die Casting in the Automotive Industry

In the automotive industry, die-casting is the most commonly used casting method, which can reduce mold weight, reduce costs, and shorten delivery time. Although the strength of die castings is low, they have good mechanical strength and elongation. It is widely used in automobiles, such as various structural components such as engine blocks, engine covers, cylinder blocks, and shells, as well as plastic parts used for car casings and bodies. In recent years, the application of die casting in the automotive industry has become increasingly widespread, and it will maintain a growth trend in the future.

1. Important parts in automotive manufacturing

For a long time, car manufacturing has been ongoing around the world. In the automotive manufacturing industry, many industries cannot do without components, which are important factors affecting the entire automotive manufacturing process and quality. For example, if a car is scrapped during the production process, its components will be recycled and reused; If a car loses most of its parts, its maintenance costs will increase. Automobile manufacturers have strict control and quality requirements for their product production process, but automotive components are closely related to the automotive production process. Therefore, in order to ensure the smooth delivery of automobiles, production enterprises must strictly implement quality control plans, ensure that vehicle quality meets emission standards and obtain approval, and the prerequisite for obtaining approval is to obtain reliable component product manufacturers.

2. Internal structure of the car

The larger the interior space of a car, the more die-casting parts are required. The internal space of the car is relatively small, so more functional components are needed, such as radiator covers, seats, dashboard, sunroof, steering wheel, and other lighter structural accessories, such as aluminum alloy parts, stainless steel parts, etc. Due to the unique advantages of automotive design, such as cost and space savings, and the ability to meet personalized needs, these components are applied in the automotive manufacturing industry. These die castings can be produced according to automotive production standards and material quality requirements. Therefore, they have high added value and can achieve standardized mass production.

3. Die cast parts and automotive assembly

In the automotive industry, many parts are made by die casting, including engine camshafts, connecting rods, and engine tailcaps. After installing these parts on the vehicle, they can effectively improve the strength and rigidity of the vehicle body. In the future, die-casting parts will continue to play an important role in the automotive industry. With the advancement of technology and the continuous development of the automotive industry, there will be more demand for die-casting parts in the future.

4. Die casting and shot peening treatment

Die casting forming refers to the process of using a die casting machine to press an alloy into a die casting mold, so that the wall of the die casting mold does not deform or deforms to form a formed part. The use of die-casting in the automotive industry can be divided into two forms: forming method and shot peening treatment. Shot peening treatment can be divided into two types: direct die-casting and indirect die-casting. Direct die-casting is suitable for most materials, such as stainless steel and its alloys, and aluminum die-casting molds, while indirect die-casting is suitable for certain materials and their casting methods. The direct die-casting referred to in this article refers to the process of compressing the die-casting mold into a vacuum state to form a part. This forming process can press the die-casting material and die-casting mold together into the interior of the die-casting machine to form a formed part.

5. Die casting forming technology

Die castings are usually formed using mold pressure and mold size. When the mold is pressed into the material, the expansion pressure generated during the forming process of the die-casting part has a high value compared to the deformation pressure. This pressure reduces defects by hardening the surface of the material, which is the pressure required for the die-casting molding process, and the die-casting needs to be tightly attached to the substrate.
