Effects such as reduction of manufacturing costs, improvement of quality and performance, and increased productivity!

As a VA/VE case, we will introduce the elimination of the welding process through cold forging. The conventional method of joining two pieces (stamped parts + fully machined parts) by welding has challenges such as high costs, the need for inspections, and limitations on production capacity. The new technology and method of cold forging as a single unit offers benefits such as reduced manufacturing costs due to the elimination of the welding process, improved quality and performance, and increased productivity. 【Customer Challenges with Conventional Method】 ■ Labor involved in the welding process: High costs ■ Stabilization of quality and performance due to the welding process: Inspections required ■ Production lead time due to the welding process: Limitations on production capacity *For detailed information on the case, please refer to the related link. For more details, feel free to download the PDF or contact us.
