Industry Introduction

The automotive industry is a vast and dynamic sector encompassing a range of companies and organizations involved in designing, developing, manufacturing, marketing, and selling motor vehicles and their various parts and accessories. With tens of thousands of parts making up a single car, these parts can be divided into different categories: engine, transmission, braking, steering, suspension, and electrical systems. Most commonly, manufacturers deal with the production of auto parts for cars, trucks, motorcycles, and other heavy equipment.

Based on the raw materials, auto parts can be categorized as metal, plastic, and electronic components. However, aluminum, magnesium alloy, zinc alloy, and copper alloy castings are some of the popular metal materials used in the manufacturing of automobiles. Downstream users particularly favor aluminum alloy castings due to their lightweight, high specific strength, good corrosion resistance, and casting process.

Manufacturing Needs

The automobile industry has complex and multifaceted manufacturing needs that require attention to several key areas. As the automobile industry evolves, there is an increasing need for lightweight and energy-efficient vehicles driven by customers’ demands for better performance. Therefore, the industry is exploring various lightweight materials and manufacturing processes to attain outstanding safety performance. Among several materials, aluminum alloys have emerged as a preferred lightweight material for auto parts with low density, high strength, and easy formability. Usually, die-casting is a preferred manufacturing process for aluminum alloy parts, as it offers excellent precision and high production volumes. Die-casting parts are commonly used in the power system, chassis system, and vehicle body.

Integrated die-casting is another latest manufacturing process that acts as a game-changer in the automotive industry. This process replaces traditional stamping and welding processes, which can be complex and time-consuming. This process lets manufacturers die-cast multiple aluminum alloy parts into one or two large aluminum castings. This process simplifies the vehicle body’s structure and improves auto parts’ integration. Tesla is one of the companies leading the way in integrated die-casting technology, using giant die-casting machines to achieve one-time molding. Thus, by adopting this technology, companies can gain competitive advantages and meet the evolving needs of customers and the industry.
