Nichigo Industry Co., Ltd. Technology Introduction "Bulge Forming"

Nichigo Industry Co., Ltd. Technology Introduction "Bulge Forming"

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.
