豊国工業 Company Overview

As a precision cutting manufacturer, we contribute to a wide range of industrial fields. We perform mass production processing of small quantities and various types, as well as single-item processing, capable of handling difficult-to-cut materials and high-precision geometric tolerances.

We are committed to precision cutting and develop and manufacture our own machine tools, inspection equipment, and automation. We propose stable and optimal manufacturing processes tailored to production volume, from materials and products to mass-produced items and single-item processing. **Specialized Technologies** 1. Mass production of difficult-to-cut materials (small, variable, and large quantities) 2. Process design and measurement design to accommodate high precision in geometric tolerances 3. Thin-walled processing, deep hole processing, angled hole processing, intersecting hole processing, burr-free processing We have dedicated lines designed in-house for mass production of automotive fuel injection system components, as well as production processes for short lead times and various small quantities. We are also certified under JIS Q 9100 (AS 9100: quality standard for aerospace components) and can ensure traceability. Additionally, by performing anodizing surface treatment in-house, we can provide integrated production from processing to surface treatment. With the slogan "Think Every Day," our production site, full of creativity and ingenuity, is a source of pride for all employees. We invite you to visit our company.
