Our Story
Company Development History
Our journey began in 2007, when Mr. Wang founded a stamping and machining business, focusing on delivering reliable metal processing solutions to industrial clients. With a strong commitment to quality and continuous improvement, the company quickly built a solid foundation in the field of metal fabrication.
As market demand grew, we steadily expanded our production capabilities by investing in advanced equipment and skilled technicians. We gradually extended our product range to include mandrel bending, exhaust pipes, and welded components, serving industries such as automotive, truck exhaust systems, and machinery manufacturing.
In 2015, we established Ningbo Guxuan Auto Parts Co., Ltd., marking an important step into the automotive parts sector, especially in the development and production of exhaust-related products.
To further integrate resources and enhance our manufacturing capacity, we launched Ningbo Infengde Machinery Co., Ltd. in 2019, focusing on a broader range of tubular components, mandrel bends, and custom metal fabrication services.
In March 2026, the company was officially renamed to INFENDE INDUSTRIES CO., LTD, reflecting our evolution into a more diversified and international-oriented manufacturing enterprise.
