[Case Study] Mass Production of Thin Stainless Steel
Solve issues such as variations in quality during mass production and complicated management!
At Seiko Industrial, we provide a consistent response from sheet stainless steel processing and welding to inspection and shipping, establishing a mass production system that balances stable quality and productivity. We address challenges such as variations in quality during mass production and distortions or dimensional discrepancies occurring from processing to welding. By optimizing processes, we contribute to stable supply with reduced variations and a decrease in subsequent processes. 【Customer Challenges and Requests (Partial)】 ■ Variations in quality occur during mass production ■ Distortions and dimensional discrepancies occur from processing to welding ■ Many defects and rework during assembly ■ Prototypes were good, but quality is not stable in mass production ■ Management is complicated due to different outsourcing partners for each process ■ Unable to respond to delivery delays or sudden increases in production *For more details, please download the PDF or feel free to contact us.

Our company primarily focuses on welding processing of stainless steel sheets ranging from 0.3mm to 1.5mm, making it the core of our technology, and we have been dedicated to producing products that require precision and quality. We particularly excel in TIG welding of thin stainless steel and are optimizing both welding conditions and process design to address challenges such as distortion due to heat, melting, and appearance defects. In thin sheet welding, fine adjustments to conditions based on material properties, shapes, and required functions significantly influence quality. We conduct welding management that emphasizes the melting state and bead shape, achieving a balance between appearance quality and functional quality. We also ensure stable quality for areas requiring airtightness and durability. Additionally, we provide proposals from a manufacturing perspective that considers weldability from the design stage, suggesting optimal structures that take into account not only quality but also processability and reproducibility. We consistently support our customers' product development and manufacturing as a partner focused on solving technical challenges, from prototyping to mass production.
