In the electric vehicle, 'Giga Casting' manufacturing method was adopted by Toyota and Volvo Chinese Geographic Motors, followed by Tesla in improving cost reduction performance.
Gigacasting is an innovative method in which a house -sized giga press is a mold press, and then it is replaced with a mold, and then cooled quickly, and usually more than 100 individual metal parts are welded together to make the body.
Toyota has applied its application to the manufacturing of electric vehicles, and the leader was added to Tesligo Volvo and Chinese geography.
Tesla used the first aluminum die -casting machine adopted Giga Press in the production of electric vehicles in the US, China and German factories.
Tesla's Elon Musk said that the EV Model 3 removed 600 robots from the giga press assembly using a single component on the front and rear of the vehicle.
Reuters said on the 14th that it is decisive to reduce the weight of the vehicle of the electric vehicle, especially the importance of electric vehicles that can exceed 700 kg of battery packs.
In the development of aluminum alloys, which traditionally omit heat treatment, which traditionally omit the heat treatment, which is traditionally processed, Tesla is made of 80 kg (176LB) of melting aluminum shots into the mold, molded it into parts, and then released to cool it.
Toyota said on the 12th, "We expect that the use of aluminum die casting will be used to remove dozens of sheet metal parts and reduce waste from assembly."
Reuters are limited to China's Italy China, which produces the initial investment costs of $ tens of millions of dollars.
Tesla has been a press from IDRA, headquartered in Italy, a subsidiary of LK Industries, China since 2008.
The rivals of IDRA in Italy and LK in China are limited to European Buhler Group, Japan's UBE and SHIBAURA MACHINE, China's Yizumi and Haitian.
The automotive companies that approach Giga Casting include Zeekr of Volvo (GEELY) and Chinese Geographic Motors in China, and are planning to plan polestar in the US GM, Hyundai Motor, and China's Geographic subsidiaries. Reuters said.
Zeekr, a Chinese automotive company, has begun to use a huge aluminum die cast for a multi -purpose van in China and told Reuters that it will introduce this technology to other models.
Volvo has invested more than $ 90 billion in last year to upgrade the factory near the Swedish Yothburi to Mega Press technology.
Reuters reported that existing automakers have already had complex product lineups and depreciation factory machines, making it more difficult to make tens of millions of dollars in new casting technologies.
Analysts said, “A car with a single piece of car can be more difficult to repair after an accident or more expensive, which can increase the operating cost of electric cars.” "It's often treated, because there are many cases where there is no way to repair a slightly damaged battery pack."
Toyota's 'Giga Cast' said, “We can contribute to the development cost of vehicle development and factory investment, which is the future of manufacturing by realizing the massive integration of parts.”
Toyota said in a description of the electric vehicle production on the day, "The use of 'gigacast' large casting parts has been expanded to 3.5 million units worldwide before 2030."
Toyota's Giga Cast applies a single component single process production through a single casting of the lower parts of the vehicle body, which was produced with 86 parts connections in the existing 33 processes.
The original name ‘Giga Press’ is an aluminum die-casting machine that Tesla first operated at factories in the US, China and Germany, and the common ‘Giga’ came from Tesla’s custom of naming its factories “Giga Factories.”
Other automakers call it "megapress", meaning a huge machine.
