Infende Industries – Pipe bending expert in China
Infende industries, We are a professional pipe bending OEM manufacturing company specializing in metal tube fabrication and machine components. We committed to delivering high-quality products and reliable production services to customers worldwide.
Our journey began in 2007, when Mr. Wang founded a stamping 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, stamping, 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, CNC machining and custom metal fabrication services.
In March 2026, officially rename company to INFENDE INDUSTRIES CO., LTD, reflecting our evolution into a more diversified manufacturing enterprise.
