Die Stamped Brass Custom Coins - Brass coins are typically crafted through die stamping. We use hydraulic machines to die stamp the patterns onto brass coins. In contrast, the designs of zinc alloy coins are produced by die casting injection molding. Please refer to the following video for more information on brass die stamping and zinc alloy injection.

Zinc Alloy Injection - This video on the zinc alloy injection process clearly differentiate die stamping brass and zinc alloy injection methods. The molten zinc alloy is injected into molds at high pressure, allowing for complex shapes to be formed with ease. This method not only enhances production speed but also results in durable and high-quality products.

Diamond Cut Rim on Brass Coins - Diamond cut on a coin rim is an exquisite craft that enhances the overall effect of a coin. The diamond-cut rim is done after the electroplating procedure and is the final step for brass coins. Diamond cutting exposes the true metal color of the coin, which is different from the coin's plating color, creating a two-tone illusion.

Diamond Cut Rim on Zinc Alloy Coins - The diamond cut made on zinc alloy coins will always be the same color as the coins because they are electroplated after the diamond cut. The exposed zinc alloy through the diamond cut must be electroplated soon to prevent oxidation, which could otherwise tarnish their surface. The diamond cut design, coupled with the electroplating technique, not only enhances the visual appeal of the coins but also safeguards their quality for years to come.

Lathed Coin Edge - When the edge of challenge coins will be stamped with letters or URL, the coin edge must be lathed to get a clean and smooth surface. This process of lathe-turning the coin edge is crucial to ensure that the letters or URLs stamped onto the edge are easily readable and aesthetically pleasing.

Challenge Coin Edge Lettering - The process of adding edge text to a challenge coin is meticulous and requires attention to detail and precision. By incorporating edge text, the coin gains an extra level of individuality and charm. The creation of a separate mold dedicated to the edge text ensures that the text is seamlessly integrated into the design of the challenge coin. Watching the video will provide you with a visual demonstration of how this intricate process is carried out.
