Recently, Gaohe Automobile and Tuopu Group jointly announced that the first integrated super die-casting body rear cabin based on the forward development of a 7200-ton giant die-casting machine in China was officially mass-produced. That is, at the end of last year, Huaren Express Gaohe Automobile and Shanghai Jiao Tong University Light Alloy National Engineering Center launched the mass production application of Low Carbon Aluminum Alloy Material for Super Castings in TechCastTM.
Huaren Express Gaohe Automobile is a technology enterprise with subversive product research and development ideas and car manufacturing capabilities, and Tuopu Group is a leading domestic auto parts research and development and manufacturing enterprise, and the two sides jointly explore the mass production application of forward-looking technologies such as vehicle body, chassis, thermal management and air conditioning systems in intelligent vehicles. This time, the integrated super large die-cast body structure parts launched by the United Nations will further consolidate the forward-looking technology leadership of both sides in the field of intelligent vehicles, and will be applied in large quantities in the subsequent models of Gaohe Automobile, and Gaohe Automobile will continue to create a techluxe technology luxury experience for users with leading technology.
Through continuous iterative virtual simulation and bench test verification, Huaren Yuntong Gaohe Automobile and Tuopu Group will finally mass-produce the integrated super large die-casting body structure parts developed and manufactured based on the 7200-ton giant die-casting machine, which marks the first domestic automaker in China to mass-produce and land the technology.
In automobile manufacturing, aluminum alloy parts can generally replace steel structures with 20% to 30% weight reduction, thereby achieving lightweighting, reducing energy consumption, and improving vehicle mileage; integrated die-casting technology has the characteristics of efficient integration and flexible design compared with the traditional body process; integrated die-casting molding, without the complex process of stamping first and then welding, realizing the reduction of the number of parts and the simplification of the connection process. Moreover, the recycling rate of integrated mold materials is close to 100%, which is more low-carbon and environmentally friendly.
The mass production of the structural parts of the rear compartment of the integrated super die-casting vehicle will become an "innovation code" to improve production efficiency and achieve a high degree of lightweight, and promote the integrated design of the integrated parts of the whole vehicle in the industrial chain, the independent research and development of transformative materials, and the iterative upgrading of giant die-casting equipment.
The integrated super large die-casting body of the off-line is based on the low-carbon aluminum alloy material of the TechCastTM super casting made by Huaren Express Gaohe Automobile at the end of last year and the World Premiere of the National Engineering Center for Light Alloys of Shanghai Jiao Tong University. TechCastTM high-carbon aluminum alloy material for oversized castings is a heat-free alloy material, which is a major breakthrough in low-carbon alloy technology at the manufacturing end of the automotive industry, bringing pioneering car-side applications to the industry. The fluidity of the material is more than 15% higher than that of the same level of material, and the strong plastic product is more than 30%, which ensures that the performance of the whole vehicle collision reaches a higher dimension.
