Stamping, Casting & Coining
Our factory operates multiple metal forming processes including die stamping, die casting, and coin striking. These techniques allow us to produce metal components with clear relief details and stable structure. Stamping is commonly used for items such as medals, lapel pins, and metal tags, while coin striking creates the deep relief found on challenge coins and commemorative coins. Each production line is carefully controlled to ensure uniform thickness and precise shaping.
