Introduction to Tsukuba Iron Works, specializing in hydraulic piping manufacturing and pipe bending processing products.
Tsukuba Iron Works' "1D bending process" is a processing technology that allows pipes to be bent with a pipe diameter and bending radius (R) that are nearly equal to 1. Bending a pipe with a diameter and bending radius of approximately 1 to 1 is referred to as 1D bending (extremely small R bending). When R becomes small, it becomes difficult to bend the pipe without causing cracks. At Tsukuba Iron Works, thanks to years of know-how and experience, we can perform 1D bending processing on small to large diameters ranging from φ34 to φ114.3. Additionally, we possess various molds for 2D, 3D, and other bending processes, allowing us to accommodate any conditions. 【Processing Examples】 ■φ76.3/R80 ■φ48.6/R50 *For more details, please refer to our catalog or feel free to contact us.

Company information
Founded in 1950. Manufacturing hydraulic piping for large construction machinery in Ota City, Tokyo. We handle everything in-house from material procurement, cutting, pipe bending, secondary processing, welding, to painting. To meet a wide range of needs, we possess numerous bending molds, including 1D bends (minimum R) with a maximum diameter of φ114.3. In June 2018, we established a new factory in Joso City, Ibaraki Prefecture for zinc phosphate coating (Parkerizing) and painting. By being able to perform surface treatment in-house, we have successfully reduced delivery times and costs significantly. With a 7m³ tank, we can also process relatively large products.
