What Materials Are Typically Used for Sheet Metal Parts at Daihatsu Parts?

In the production process of Daihatsu Parts, the selection of materials for sheet metal parts is crucial, directly affecting the strength, weight, durability, and cost-effectiveness of the components. Generally, Daihatsu Parts uses the following main materials for its sheet metal parts:

High-Strength Steel (HSS) and Ultra-High-Strength Steel (UHSS): With increasing safety requirements, Daihatsu Parts uses more and more high-strength steel (HSS) and ultra-high-strength steel (UHSS). These materials have extremely high tensile strength and impact resistance, providing additional protection during collisions and ensuring the stability of the vehicle body structure under extreme conditions. Furthermore, ultra-high-strength steel can effectively reduce the thickness and weight of the vehicle body while maintaining sufficient strength, thus improving safety.

Aluminum Alloy: To achieve lightweighting, Daihatsu Parts uses aluminum alloys in some sheet metal parts. Aluminum alloys are not only lightweight but also possess excellent corrosion resistance, making them particularly suitable for manufacturing large sheet metal parts such as the body and roof. The use of aluminum alloys not only reduces overall vehicle weight but also improves fuel efficiency and dynamic performance.

Magnesium Alloys: In some high-end and specialty models, Daihatsu Parts may use magnesium alloys to further reduce weight. Magnesium alloys have a lower density than aluminum, providing a more significant weight reduction effect without sacrificing strength.

Stainless Steel: To improve the corrosion resistance of sheet metal parts, Daihatsu Parts also uses some stainless steel materials, especially in highly protective components (such as the exhaust system and underbody protection plates). These effectively prevent rust and extend service life.

Behind the selection of these materials, Daihatsu Parts considers not only the physical properties of the components but also the cost-effectiveness of the production process and the market's demand for environmental protection and lightweighting. By optimizing material selection, Daihatsu Parts ensures safety while also improving fuel efficiency and the vehicle's environmental performance.

How ​​do Daihatsu Parts address lightweighting and energy efficiency requirements for sheet metal components?

At Daihatsu Parts, lightweight design has become a key industry requirement. With increasing global focus on environmental protection and energy conservation, automakers, especially brands like Daihatsu that primarily produce small and economy cars, must consider how lightweight design can improve fuel efficiency and reduce emissions.

Application of Aluminum Alloys and High-Strength Steel: To achieve lightweighting, Daihatsu Parts extensively uses aluminum alloys and high-strength steel (HSS) in the body and structural components. These materials are lighter than traditional steel while possessing similar or higher strength, effectively reducing the overall vehicle weight. A lightweight body can significantly reduce vehicle energy consumption, especially during city driving and short-distance trips.

Design Optimization and Structural Lightweighting: In addition to material selection, Daihatsu Parts also emphasizes the structural optimization of sheet metal components. Utilizing advanced engineering tools such as Finite Element Analysis (FEA), Daihatsu can design lighter structures by eliminating unnecessary materials while maintaining component strength and functionality. For example, the sheet metal design of the body frame and doors can employ distributed stiffeners and hollow structures to achieve weight reduction.

Recyclable Materials: Daihatsu Parts emphasizes the use of recyclable metal materials, such as aluminum alloys and steel. These materials not only provide lightweighting during production but can also be recycled after the vehicle is scrapped, aligning with sustainable development principles. This recycling of materials reduces resource consumption and environmental burden.

Powertrain Optimization: In addition to lightweighting, Daihatsu Parts further reduces overall vehicle energy consumption in line with the development of electrification and hybrid systems. For example, electric and hybrid vehicles typically feature lighter sheet metal components to support more efficient powertrains.

Through these measures, Daihatsu Parts is able to reduce vehicle weight while ensuring vehicle performance and safety, meeting modern consumers' demands for fuel economy and environmental friendliness.
