Increased profitability, megacasting solutions for China

Bühler, Uzwil (CH), is supplying four new Carat 92 megacasting solutions to the Chinese automotive supplier Duoli Technology, Wuxi, China. The company also increased its profitability in 2023 with growing sales, higher order intake and an 8.9% increase in EBIT.

Duoli produces large castings for many well-known global OEMs in the automotive industry. The supplier entered the die casting business in December 2020 and started its collaboration with Bühler with the installation of the Carat 610 megacasting solution in 2021. Thanks to the reliability and consistent quality of the Carat 610, Duoli won further orders and had to increase its production capacity. The purchase of a first Carat 920 and two more Carat 610s was the next logical step. On December 18, 2023, Duoli celebrated the start of production with the Carat 920 at its plant in Yancheng.

The Carat series is Bühler's answer to the accelerating global trend towards larger structural castings in modern vehicle architectures. The two-platen technology with clamping forces of 10,500 to 92,000 kilonewtons (kN) is specially designed for the production of large and complex parts such as front and rear underbodies in one piece.
