TECHNOLOGY

Mitsuchi’s cold-forging technology, composed of forging formers and forging presses — it makes possible large-volume product with machining in short times and at reduced cost, and achieves high wear resistance and high durability through processing that does not damage the metal fiber flow. The experience accumulated over many years by our on-site operators serves as the basis for die design using expertise cultivated through in-house production, process design backed by our track record of manufacturing several thousand components, and also taking total advantage of CAE analysis and other techniques, through which we maintain high levels of manufacturing precision.

We can accommodate a wide range of cutting operations, including lathe machining, milling, and other forms of machining. We can select the optimal cutting methods according to such factors as machining method and product configuration and carry out processing accordingly.

Making full use of the technology in rolling-tool design and machine adjustment that we have cultivated heretofore, we are capable of heat-treating high-strength bolts of over 12-ton class, then performing thread-rolling, thereby improving product performance.

Quick joints are patented and utility-model products of Mitsuchi’s own innovative design. Because they can form a link simply pressing them in, they achieve automation in assembly and labor savings in operations, contributing to shorter work times. This technology with a proven record of performance of over 30 years in the construction industry finds use in such applications as shield-method tunnel projects.
