新潟三吉工業 List of Products and Services

We would like to introduce our "Quality Assurance System." Starting with five three-dimensional measuring machines, as well as projectors, measuring microscopes, and shape measuring instruments, we conduct rigorous inspections daily using a wide range of measuring equipment at full capacity. Our comprehensive system includes certified inspections during new launches, initial flow inspections until quality stabilization, incoming inspections upon receipt of parts, process inspections during production, and shipping inspections at the time of dispatch. 【Equipment Owned】 ■ Three-dimensional measuring machines: 3 Mitutoyo, 2 Tokyo Seimitsu ■ Non-contact three-dimensional measuring machine: 1 OGP ■ Roughness measuring instrument: 1 Tokyo Seimitsu *For more details, please refer to the PDF document or feel free to contact us.

Our company has received approval for the "Fiscal Year 2007 Strategic Base Technology Advancement Support Project" and is working on the development of metal separators used in fuel cell cells, with the Japan Metal Press Industry Association as the managing organization. Metal separators require high-density grooves that allow air and hydrogen to pass through, and the depth of these grooves is several times the thickness of the plate, which can cause warping and distortion during press processing. Miyoshi has solved these issues of warping, distortion, and thinning cracks with its unique methods. By mass-producing through press processing, we can address the cost issues of fuel cells and contribute to the establishment of a hydrogen energy society. [What is a fuel cell separator?] - A type of power generation device that generates electricity through the chemical reaction of hydrogen and oxygen. - The main body of the fuel cell consists of stacked plates. - The amount of electricity generated by a single cell is minimal. - By stacking them, a significant amount of electricity can be obtained. *For more details, please refer to the PDF document or feel free to contact us.

Our "Sheet Metal Assembly" finishes various sheet metal parts into the desired enclosures through welding methods and riveting assembly processes. We can also produce units (assemblies), significantly reducing the management workload for our customers. Prototype procurement is also possible for parts from different industries (plastic, shafts, rubber, electrical components, etc.). 【Features】 ■ Finishes various sheet metal parts into the desired enclosures through welding methods and riveting assembly processes. ■ Prototype procurement is possible for parts from different industries (plastic, shafts, rubber, electrical components, etc.). ■ Can also produce units (assemblies), significantly reducing the management workload for our customers. *For more details, please refer to the PDF document or feel free to contact us.

Our company specializes in precision sheet metal processing. We have a comprehensive system and equipment that covers everything from prototyping to mass production. We can provide technical proposals from the prototyping stage of new model development. For short lead-time prototypes, we also utilize traditional methods such as kicking to ensure stable bending with minimal variation. *For more details, please feel free to contact us.

Our company is engaged in the design and manufacturing of precision metal press molds, as well as mass processing of press parts. We have processing experience with iron-based materials such as SPCC and SECC, as well as stainless steel, aluminum, copper, and titanium, with thicknesses ranging from t=0.05 to t=5.0. For products processed with single-stage molds, we have implemented robotic lines to reduce costs, leading to a decrease in product prices. Please feel free to contact us with any inquiries. 【Features】 ■ Design using CAD/CAM ■ Mold manufacturing ■ For large lot products, we respond with progressive molds *For more details, please download the PDF or feel free to contact us.
