To procurement and maintenance personnel who have been turned down for old drawings or small orders! Solve it with our 55 years of expertise in large round material processing in Chiba, and achieve zero procurement anxiety.

There are many processing companies, but I want to work with a company that has a proven track record and can be trusted to handle large, round individual items with confidence... Are you feeling uncertain about the quality of your outsourcing partner? - I chose an outsourcing partner based solely on price, which led to delays and dimensional defects, causing me to struggle with rework. - Since these are critical components essential for equipment maintenance, I want to rely on a company with extensive experience and trustworthiness. - I am looking for a partner for large-scale processing in the Chiba and Kanto area where I can have close meetings and consultations. Iwai Koki, which has supported the difficult processing of plants and steelworks for over 55 years since the Showa era, will fundamentally resolve these concerns. [Three Strengths to Solve Your Challenges] - Overwhelming trust and track record of more than 55 years: Extensive experience in processing infrastructure components where mistakes are absolutely not allowed, such as plants, steelmaking, and rotating machinery. - Advanced collaboration in large-scale lathes and machining: Processing of large diameter workpieces, round items, flange shapes, ring shapes, and thick components through optimal routes. - Numerous successful consultations for drawing updates and physical updates: Many successful replacements from situations like "only the physical item exists" or "the drawings are in tatters." *For more details, please download the catalog or feel free to contact us.

Applications/Examples of results

Plant, steelmaking, and energy-related equipment management processes: Manufacturing of large repair parts that require high durability, used in harsh environments (steelmaking equipment, chemical plants, power plants) where 24-hour operation is assumed. Processes looking for suppliers in the "Kanto area, Chiba": Acting as a procurement contact for companies around the Tokyo metropolitan area and the Keiyo industrial region that want to "discuss processing methods directly" and "meet while viewing the actual items." "Extending the lifespan and modernization of production equipment": The process of reproducing and newly manufacturing large round flanges, rings, and shafts that were discontinued 30 to 40 years ago when updating industrial machinery. Cases where "in-house processing and existing outsourcing are insufficient in specifications": Large and thick metal processing requiring a chuck diameter that cannot be handled by the company's machine tools or typical small factories. Response area: Optimized for small lot production of 1 to about 10 pieces, providing high satisfaction not only for repeat items but also for completely custom-made products.
