HOW WE WORK
SKILLED HANDS.
THOUGHTFUL ENGINEERING.
We combine digital tools with the practical judgment of experienced craftspeople. Welding, straightening, and finishing depend on skills developed through hands-on work.
Our approach is to understand what a product needs to do, review the drawing and manufacturing method, and work toward the agreed quality, cost, and delivery requirements.
OUR HISTORY
ROOTED IN MAKING.
Kiyoyuki Murashita starts the business, initially focused on architectural metalwork.
SEIKO CO., LTD. is established to expand into sheet metal fabrication.
Masaki Murashita becomes president in October, continuing the company’s manufacturing work into its next chapter.
