Yumoto Electric Co., Ltd. (Headquarters: Osaka City, Osaka Prefecture, Representative Director: Hideaki Yumoto), which conducts contract manufacturing of custom parts at the prototyping and development stages, fully operationalized all lines of its new factory completed in February 2026, starting in April. This facility introduces a total of 9 processing machines, including a state-of-the-art 5-axis machining center equipped with 32 pallets. Two months of production line optimization since the start of operation have been completed, establishing a stable supply system for complex shapes made from difficult-to-cut materials.

## [Background] The Reshoring of the Manufacturing Industry and the Strengthening of Supply Chains in Prototype Development
In recent years, against the backdrop of rising geopolitical risks and supply chain disruptions, the 'reshoring' (domestic return) of crucial components is accelerating in the Japanese manufacturing industry. Particularly in the prototype and development phase, which determines the added value of a product, the importance of stably procuring high-quality machined parts domestically is being reaffirmed.
However, in domestic manufacturing sites, there is a lack of supply capacity capable of handling difficult-to-cut materials such as titanium and PEEK, as well as advanced 5-axis machining, resulting in a chronic issue where designers 'cannot find the optimal processing partner domestically.' Such bottlenecks in the domestic supply chain are a major factor stagnating the speed of Japan's research and development.
Yumoto Electric launched the 'Shin-Machikoba Project' in 2022, aiming to re-strengthen the domestic manufacturing foundation in response to these social demands and customer needs. To break away from overseas dependence and build a system that completes highly difficult cutting processes domestically, they spent four years promoting the introduction of state-of-the-art automated equipment and accumulating technical know-how. Following its completion in February 2026 and two months of thorough actual machine testing, all production lines are now in full-scale operation.

## Enhancing Capability for High-Difficulty Projects with a 32-Pallet, 24-Hour Operational Line
At the new factory, the following systems were constructed for new business expanding the correspondence area:
- Establishing a stable supply system for 'complex shape processing of difficult-to-cut materials' like Titanium and PEEK
A dedicated line was built specifically for cutting difficult-to-cut materials such as titanium, which is seeing a rapid increase in demand in the aerospace, medical, and advanced energy fields, as well as complex shapes. Highly difficult and complex-shaped projects that were previously impossible to handle can now be accommodated.
- Seamless transition from prototyping to mass-production prototyping using a '32-pallet x 5-axis machining center'
Introduced a '5-axis machining center equipped with a pallet changer' capable of stocking 32 workpieces each for metals and resins. In addition to high-mix low-volume single-item prototyping, unmanned operation has realized shorter lead times even in 'pre-mass production prototyping' where both speed and quantity are simultaneously required.
- Securing flexible capacity through an 'Automated Line'
By building an automated line that does not rely on manual labor, capacity was secured to flexibly respond to sudden design changes and short-delivery requests from in-house engineers. This secured time to create added value beyond just making parts according to drawings, such as design proposals considering processing that balances cost reduction and performance improvement.
