MOVIE BY YUICHIRO FUJISHIRO
The “CHARMANT-MADE” Production Line
Before production begins, design data is finalized through extensive discussion, verification, and process planning. Based on these specifications, the molds and jigs required for manufacturing are prepared. Once preparations are complete, frame production begins. The manufacturing of metal frames typically involves around 200 individual processes.
However, The production of Excellence Titan frames may involve 300 or more processes. On the CHARMANT-MADE production line, parts move continuously through forming, joining, treatment, and assembly stages. A specialized
management team monitors each step to ensure that production proceeds smoothly and meets CHARMANT’s strict quality standards.
