From first drawing to stable mass production.
Tooling design, high-speed stamping, assembly and inspection run under one roof. One team owns your part from DFM review to repeatable volume, so tolerances hold from the first sample to the millionth piece.
-
Engineering support
DFM review, lamination design and prototype samples aligned to your motor specification.
-
Precision stamping
High-speed progressive stamping of electrical steel with stable burr and flatness control.
