Challenging cost reduction through shipping transformation and material savings! A technology invented in Japan for the world.
"Bulge forming" is a hollow forming process for metal pipes in which a pipe set in a mold is filled with ultra-high-pressure liquid while compressing both ends of the pipe axially, allowing it to be processed all at once into the shape engraved in the mold. It is also called hydroforming and involves plastic processing of pipes made from carbon steel, stainless steel (SUS), aluminum, copper, brass, and various alloys. This method contributes to reducing environmental impact and lowering product costs through material savings. We can accommodate custom-made products according to the design and development concept, so please feel free to consult with us. 【Benefits】 ○ Lightweight and thin-walled ○ Reduction in the number of parts ○ Transition in materials and manufacturing methods ○ Realization of cost reduction For more details, please contact us or download the catalog.

basic information
【Processing Range of Bulge Forming / Hydroforming in Japanese Industrial Manufacturing】 ○ Pipe Diameter: 15mm to 100mm ○ Wall Thickness: 0.8mm to 4mm ○ Product Length: 40mm to 700mm 【Approximate Calculation Formula for Combination Processing Limits based on Outer Diameter (D), Wall Thickness (T), and Length (L)】 ○ D×T×L < C (constant) ○ C: Steel 30,000, SUS 25,000, Copper/Brass/Aluminum 35,000 ○ Calculation Examples → Outer Diameter = 60mm, Wall Thickness = 3mm, Total Length = 150mm 60×3×150 = 27,000 27,000 < 30,000 ⇒ Production Possible → Outer Diameter = 30mm, Wall Thickness = 2mm, Total Length = 400mm 30×2×400 = 24,000 24,000 < 30,000 ⇒ Production Possible → Outer Diameter = 100mm, Wall Thickness = 2.5mm, Total Length = 200mm 100×2.5×200 = 50,000 50,000 > 30,000 ⇒ Production Not Possible ● For more details, please contact us or download the catalog.

Company information
Nikko Industry Co., Ltd. specializes in hydraulic bulge forming (hydroforming) using materials such as metal pipes and plates as its core technology, enabling the shaping of three-dimensional forms that are difficult to achieve with traditional casting and pressing techniques. Our commitment to bulge processing began with the use of a patent invented by the Industrial Technology Institute in 1963, and we have felt a growing demand for further application development due to the remarkable advancements of this method in the recent automotive industry in Europe and the United States. Leveraging our extensive experience and rich track record, we utilize a variety of uniquely developed plastic processing technologies for pipes, both hard and soft, and by adopting bulge forming that leads to a shift in thinking, we aim to propose improvements in safety and quality, as well as the potential for cost reduction through weight reduction and significant labor savings to various users. We are committed to making efforts toward realizing product development that meets your expectations.
