"Special large-scale processing that was declined by other companies" - Single item processing of large round shapes and flange shapes.
Where to ask for... If you're troubled by large round parts and flange-shaped individual machining, we can solve it with 55 years of design and machining expertise that leads to practical processing methods.
With this size and shape, which processing company would even accept it...? Have you been searching for hours online for subcontractors? - Existing partner companies have been reluctant, saying it's 'too big' or 'too complicated for a round object.' - I want to do not only new production but also some minor additional processing or repairs, but I have no one to ask. - There are many design changes, and I want someone who can respond quickly to prototypes and small lots. 'Not knowing where to ask'—Iwai Koki will fundamentally solve all those issues. 【Three strengths that solve your problems】 - Technical capability that 'doesn't say no': With over 55 years of experience, we can shape works that other companies give up on, saying 'it's difficult to set up.' - Perfect fit for large diameters, thick materials, and round objects: Equipped with large lathes and machining centers, we cover the optimal environment for processing large flanges and rings. - Flexible for additional processing and prototypes: We can handle not only new production from scratch but also additional processing requests like 'I just want this part shaved down a bit' for existing components. We fully understand the pressure of a site where 'equipment absolutely cannot be stopped'! *For more details, please download our catalog or feel free to contact us.

Applications/Examples of results
Verification process in the "design phase" or "prototype phase": A quick prototype machining to create just one piece of large equipment parts or large diameter round prototypes before mass production. "Domestic additional processing" of parts from other companies or overseas: A process to perform additional processing or modifications such as drilling, tapping, and grooving on already finished large flanges or rings. "Minor changes" to equipment and lines: The production of individual items such as mounting brackets for existing industrial machinery, dedicated jigs, and custom thick washers due to changes in the production line within the factory. An emergency situation where "the existing processing supplier is at capacity": A procurement scene where, despite tight deadlines, the usual outsourcing partner is overwhelmed, and there is an urgent request for "help just this once." Wide-ranging support regardless of industry: Addressing the niche needs of any industry that requires robust and large round metal components, including steelmaking, plants, shipbuilding, construction machinery, and the foundations of large semiconductor manufacturing equipment.
