[Production Example] Some exterior parts of a fuel cell bus
A case where technical proposals were made for issues during prototype production, resulting in changes to the drawings during mass production startup!
We would like to introduce a case where we manufactured some exterior parts for a fuel cell bus. Initially, spot welding posed no issues and ensured strength; however, from the perspective of exterior parts, the finish of the welds did not meet the standards. Since the painting method did not resolve the issue, a redesign was necessary. Based on our past experience in manufacturing aluminum parts, we proposed a riveting method for joining. This resulted in a solution that satisfied the customer in terms of both appearance and strength, allowing for a design change in the joining method. 【Case Overview】 ■Challenges - The finish of the welds did not meet the standards from the perspective of exterior parts. - The painting method did not lead to a solution. ■Results - Compared to spot welding, quality control became easier. - This led to stable quality during production and reduced manufacturing costs. *For more details, please download the PDF or feel free to contact us.
