Our “240 Faces Object” received the Minister of Health, Labour and Welfare Award, and we, Nadayoshi are extremely pleased with surprise and appreciation. Thank you very much indeed.

We had an image of the finished product and we therefore, dared to create this complicated shape from one piece of unfolded sheet.

The most difficult part on this product was to find the bend angle data. We created the 3D CAD drawing and built angle gauge based on this drawing. The design was reviewed and revised many times for one piece of unfolded sheet to fit in 4x8 size sheet. The slit was processed on the sheet to bend manually as bending machine could not take the one piece of sheet, but, it was very difficult because elongation was different depending on the angle and it didn’t work out as calculated. When welding, even the slightest size discrepancy would lead to misfit at the next welding line which would result in failure, so we welded one by one by checking the angle. Furthermore, since angle adjustments weren’t allowed once the parts were welded together, so very high angle precision was required.

We owe this great award to the collective efforts of all our employees and our families’ support. We get also valuable advice from and learn together at the Kyushu Sheet-metal Industrial Association members, whom I would like to express our gratitude. From now onward, we will work to create products that would provide manufacturing hints to everyone while nurturing young professionals.
