Copper, Iron, or Aluminum | Clear Embossing | Precise Pattern Outlines
Die stamping is a technique that uses gravity or pressure to shape and pattern metal sheets into specific forms. This process can be understood as "shape punching" and "pattern pressing." First, appropriate metal materials such as copper, iron, or aluminum are selected. Each material has unique properties: copper is soft, ideal for intricate patterns; iron is hard and economical, making it a mainstream choice; aluminum is lightweight and strong, suitable for special metal products.
In the "shape punching" step, a press or mold applies gravity or pressure to form the metal sheet into the desired shape. This step involves precise mold design and efficient pressure control to ensure accuracy and consistency in forming the metal sheet. The precision of the mold directly affects the quality of the final product, so careful attention to detail and tolerance control is essential in mold design and manufacturing.
Next is the "pattern pressing" step, where a pre-carved mold is used to press the designed pattern onto the metal surface. This step requires highly precise molds to ensure the pattern details are perfectly rendered. The pressure applied must be uniform and appropriate to avoid deformation or distortion of the pattern. This step results in a clear relief on the metal surface, creating the desired intricate patterns.
After stamping, the metal products can undergo polishing to smooth the surface or be electroplated with different finishes such as gold, silver, or nickel to enhance aesthetics, durability, and corrosion resistance. This technique is especially suitable for small metal souvenirs and gifts that require clear relief and defined contours, such as badges and keychains. However, for larger, more complex, or irregular shapes, stamping might not be ideal, and die casting may be necessary.
