Summary: Toyota plans to introduce a large-scale “Gigacast” casting equipment for integrated casting of body parts at its own factory in Aichi Prefecture as early as 2024. This will be the largest casting equipment in Japan, and it is planned to be used for the trial production of parts for electric vehicles (EVs). The integrated casting technology, which improves the cost competitiveness of electric vehicles, is being adopted by companies such as Tesla in the United States. Toyota is preparing to fully launch electric vehicle production by accelerating the introduction of the latest equipment.
Integrated casting is a technology in which molten aluminum alloy is injected into a mold at high speed and high pressure at high temperatures, to integrate parts such as body parts. It is expected to help reduce the weight of the body and improve production efficiency, as it can produce large parts with complex shapes in one go.
Toyota will install a large-scale casting equipment manufactured by UBE Machinery (Ube City, Yamaguchi Prefecture) with a clamping force of 9,000 tons. The stronger the clamping force of the equipment, the larger the parts that can be manufactured. Although there is no clear definition of integrated casting, it generally refers to equipment with a clamping force of 6,000 tons or more.
Toyota said it will begin using integrated casting technology for its next-generation “LF-ZC” electric vehicle for the luxury brand “Lexus” to be launched in 2026. The plan is to divide the body into three parts, front, middle and rear, and use integrated casting technology for the rear and front. It is said that the prototype has integrated 86 parts and 33 processes in the rear into one part and one process.
