[Daiichi Jitsugyo] Promoting DX and Labor Saving in Casting Sites: Exhibiting at the Japan Foundry Engineering Society 187th National Conference

Daiichi Jitsugyo Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; President and CEO: Yuji Funato), a comprehensive machinery trading firm, will exhibit at the 'Japan Foundry Engineering Society 187th National Conference' to be held for two days on May 23 (Sat) and 24 (Sun), 2026, at Light Cube Utsunomiya (Utsunomiya City, Tochigi Prefecture). The conference is organized by the Japan Foundry Engineering Society under the theme of 'Casting Industry 10-Year Strategy' with the aim of advancing technology in the casting sector.

At the booth, the company will introduce the latest sand 3D printers and advanced automated finishing technologies, focusing on solving issues in the casting industry such as 'addressing labor shortages,' 'reducing the burden of heavy physical work,' and 'lowering environmental impact.'

## Sand 3D Printers (Ex-One / voxeljet AG)

With the integration of the 'voxeljet' and 'ExOne' brands currently underway, the lineup and application areas for binder jet technology for casting are expanding. This year, the company began handling products from both brands, establishing a comprehensive proposal structure in the sand 3D printing field. Recently, the application of sand 3D printers is accelerating from prototyping to mass production processes. It is attracting attention as a next-generation production method in the casting manufacturing sector, which requires complex component shapes and short lead times.

Moving forward, the company will provide optimal AM (Additive Manufacturing) solutions tailored to customers' production challenges, leveraging the advanced technology and know-how possessed by both brands.

## Solution for Casting Finishing Process (FINESYSTEM Co., Ltd.)

This solution achieves automation and high efficiency in the finishing process of cast products using FINESYSTEM's proprietary 'Air Float System.'

Cast products tend to have individual differences in shape and dimensions, making stable quality maintenance a challenge for conventional automated equipment.

By enhancing work followability through the company's unique air float technology, it flexibly responds to individual differences inherent in castings, achieving high-quality finishing processing.

In the finishing process, which highly relies on skilled craftsmanship, the solution contributes to labor saving, reduction of work load, and quality stabilization, thereby supporting improved productivity at casting sites.
