From mold design and manufacturing to mass production, we provide a one-stop solution for multi-process, multi-component, and multi-sourced products.

Our company, with years of cultivated experience and precision forging technology, provides a seamless service from mold design and manufacturing to mass production. We can produce high value-added products generated from improvements, even in small lots. We offer one-stop solutions for multi-process, multi-component, and multi-sourced products, contributing to reduced man-hours, shortened time, and cost reduction. This document introduces examples such as creating drawings from actual agricultural special vehicle parts without existing blueprints and carrying out mass production, as well as a case where we were consulted about whether a product originally composed of four parts could be forged all at once. [Contents (partial)] ■ Story of the solution case.01 - Hypoid B&P set (bevel gear & pinion gear) ■ Story of the solution case.02 - Straight B&P set (gear and shaft for a machine that removes weeds from rice fields) *The collection of solution cases can be viewed via the "PDF Download" link below.
