NIKKO SANGYO CO., LTD.
Bulge-formed components
Description of business
Nikko Sangyo’s core technology is hydraulic bulge formation (hydroforming) using metal pipes and plates as materials, which enables three-dimensional shapes to be formed that may be difficult when only using conventional casting and pressing technologies. Nikko Sangyo also offers proposals on reducing welding costs through burring in post processing.
Typical processed products of Nikko Sangyo
Bicycle frame fittings. Integral molding of bulging + burring. Material: STKM11A φ34 × 2.0t
Civil engineering/building materials. Integral molding of bulging + burring. Material: STKM11A φ76.3 × 1.6t

Products and Technologies
Joint fittings for bicycle frames
Bulge molding + burring + laser cut
● Fittings for handmade bicycle frames
Laser cut operation with an emphasis on design.
Blanks can also be shipped separately before cutting.
Material: STKM11A φ 31.8 × 2.0t
SUS branch pipes
Bulge molding + burring
● Bulge-molded products using stainless deep drawing as material
Burring is performed after bulge formation. Finishing can reduce the number of welding steps.
Material: SUS304 φ49 × 1.4t
Engine products
Swaging through bulging, Inconel 718 molded products
Material: STKM11A φ15×2.8ｔ
● Swaging process to integrate multiple parts
This engine camshaft is swaged through bulging by passing the pipe through the cut-out cam.
It is lighter compared to conventional camshafts because it uses a pipe for the shaft.
Material: ALLOY718 φ17.5×1.6ｔ
● Compressed air piping for air jet engines
Bulging products with excellent heat resistance of difficult-to-cut Inconel 718.
