Zero "compromise" for designers. A prototype partner for 5-axis machining and large-scale welding.
Balancing welding structures and precision machining. Completing high-difficulty prototypes and small lots with a large lathe (φ1,600), 5-axis machining, and long-length processing (1,000mm).
"While keeping costs down with welded structures, we want to achieve high precision tolerances on the reference surfaces through machining." Are you looking for a partner to realize such design philosophy? Iwai Koki combines the skilled technology cultivated over half a century with the latest equipment, such as 5-axis machining centers and large turning centers (up to φ1,600mm). We specialize in prototype projects for industrial machinery and automation device frames, chambers, and large brackets, focusing on "small lot production of various types with short delivery times." With us, you can advance from complex welded shapes to subsequent reference setting and precise drilling all in-house, allowing us to respond flexibly to sudden corrections due to design changes and strict geometric tolerance requirements. We can handle various materials, including aluminum, stainless steel, and castings. We also have processing capabilities for lengths up to 1,000mm, making us particularly adept at "large and complex custom products" that other companies may decline. For manufacturers in the Chiba, Ibaraki, Kanagawa, and Tokyo areas, we can offer flexible delivery options using our own transportation. We provide enthusiastic and sincere support from initial lots before mass production to development projects requiring technical consultation. To accelerate your development speed, please make use of Iwai Koki.

Distributors
Our company was founded in 1970 as "Iwai Iron Works Co., Ltd.," which is the predecessor of our current business, and has been engaged in machining for many years. Although we did not have our own products, from the time of our establishment, we have worked to accommodate a wide variety of small lots and short delivery times, focusing on improving both our equipment and the skills of our employees. 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.
