On April 18, 2022, the 9000T large-scale integrated rear bottom die-casting mold developed and manufactured by Ningbo Saiweida Machinery Co., Ltd. was successfully delivered, achieving another leap in the history of die-casting mold research and development.
On the same day, the mold developed by Sevida was jointly developed by Wencan Group Co., Ltd. in Tianjin Xiongbang Die Casting Co., Ltd. 9000TThe large-scale integrated body rear bottom plate was die-casted, and the first batch of products were successfully rolled off the production line. After testing, the product performance met customer requirements and reached the international leading level.
According to reports,9000TLarge-scale integrated die-casting body rear floor components, the length and width dimensions are approximately1600mm×1400mmwill be used for a new car-making head enterpriseSUVmodel.
At present, integrated die-casting has become one of the development trends of the industry, and it is the first to be applied to new energy vehicles, with huge potential and broad prospects. In recent years, my country’s new energy vehicle industry has developed rapidly. According to data released by the China Association of Automobile Manufacturers,2021year,2022In the first quarter of this year, my country’s new energy vehicle production and sales increased year-on-year1.6times,1.4times, and the market share is13.4%,19.3%.expected2022Annual sales of new energy vehicles are expected to break through50010,000 vehicles.
In this context, Sevida, which undertakes the important task of developing die-casting molds, is actively preparing for the war.already2019Yearly planning and construction ready for production6000T-20000Tof heavy duty tooling workshops, equipped with6Mi Longmen CNC,3.5Milongmen three coordinates,160T+80Tdriving,800TClamping machine, digital, constant temperature five-axis machining workshop, this year, added several more3Meter five-axis gantry CNC,80T+50TCrane, so far, has realized closed-loop production from super-large mold base processing, super-large mold core processing, super-large mold clamping and testing, and the whole process of the factory.50set6000TThe only factory in the world with a production capacity above the mold. At the same time, we will actively provide automotive lightweight overall solutions for domestic and foreign OEMs, from product design, structural optimization, risk identification, to mold design and production, participation in high-pressure casting, providing die-casting technical support, and product machining. Loading verification, etc.
In 2019, Sevida developed the world’s first 6000T large-scale one-piece rear floor structural part mold; in February 2022, it developed the world’s first 7200T large-scale one-piece rear floor structural part mold. After a lapse of two months, a 9000T large-scale integrated die-casting body rear floor die-casting mold was developed.
Chairman Ren Sailiang said that, as the preferred supplier in the global automotive lightweight field, the industrial chain and economic chain surrounding the automotive manufacturing industry are constantly being upgraded and improved. Severda will continue to vigorously develop and manufacture large-scale die-casting molds to meet the needs of the automotive manufacturing industry chain. To meet the needs of technological transformation and upgrading of enterprises, work with partners to jointly promote the high-quality development of the global automobile manufacturing industry.
It is reported that Sevida is currently developing 12000T-20000T one-piece body structure molds.
