Support for stable procurement of heavy machinery and construction equipment parts. A second source for large-scale processing.

For BCP measures in the Chiba and Ibaraki areas. In-house integrated processing with a large lathe of φ1,600 and high-strength welding. Achieving stable supply of custom products with 50 years of experience.

"Orders are concentrated on existing partner factories, increasing delivery risks." "We want to distribute orders for small-lot parts with special specifications to reliable local vendors." Iwai Koki responds to these challenges in the purchasing and procurement departments with solid technology. Based in Chiba, our company possesses numerous large turning centers, various NC lathes, and machining centers. We specialize in the lathe processing of "large and high-strength" parts used in heavy machinery and construction equipment, as well as integrated production from welding. With a stable management foundation that has been in place for over 50 years and a strict self-inspection system by our quality control department, we meet the stringent audit standards of major manufacturers. We are utilized by many customers as a strong second source to mitigate risks during disasters (BCP measures) or to supplement capacity shortages at primary factories. In addition to iron and high-tensile steel, we have extensive processing experience with castings and stainless steel, and we can finish complex optional parts and custom-made products in the prototype stage in a short delivery time. Our regionally focused delivery system using our own trucks (Chiba, Ibaraki, Kanagawa, Tokyo) contributes to reducing transportation costs and improving delivery accuracy. We resolve purchasing managers' "procurement anxieties" with our supply capabilities and stability.

In addition, in our sales activities, we have established a network with reliable partner factories to respond to requests for individual machine parts as well as complete assemblies, providing a one-stop service to our users.
