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.
