Selecting the right manufacturing method for custom metal products—whether pins, medals, keychains, or coins—directly affects cost, quality, lead time, and design possibilities. At Lifeng Crafts, we offer three primary methods: die casting, stamping, and 3D printing. Here’s how they compare.

Die Casting
Die casting involves forcing molten metal (typically zinc alloy) into a pre-formed steel mold under high pressure. This method is ideal for thick, heavy, or highly detailed 3D designs, such as challenge coins with sculpted elements or chunky keychains.
– Pros: Excellent detail reproduction, deep relief possible, durable.
– Cons: Higher mold cost, longer setup time, best for large runs (500+ pieces).
– Best for: Thick challenge coins (3mm+), sculpted medallions, premium lapel pins.

Stamping
Stamping uses a steel die to press flat metal sheets (brass, copper, iron) into shape. It’s the traditional method for thin, lightweight medals and military-style pins.
– Pros: Lower mold cost, faster production, ideal for soft enamel designs.
– Cons: Limited to 0.5–2mm thickness, less suitable for complex 3D relief.
– Best for: Soft enamel pins, thin medals (e.g., for marathons), flat keychains.

3D Printing (Metal)
Metal 3D printing (direct metal laser sintering) builds objects layer by layer from metal powder. While innovative, it is rarely cost-effective for mass production.
– Pros: No mold required, perfect for prototypes or one-off designs, unlimited complexity.
– Cons: Very high per-unit cost, rougher surface finish, limited material choices.
– Best for: Rapid prototypes, artistic pieces, very low volumes (<50 units).

How Lifeng Crafts Helps You Choose
Our experienced team evaluates your artwork, quantity, budget, and timeline to recommend the optimal method. For most commercial orders (500–10,000 pieces), we recommend die-casting for premium 3D items and stamping for cost-effective flat designs. We also offer combination techniques (e.g., stamped base with die-cast attachments).

Need a prototype?
We can produce a small batch using temporary tooling or even 3D-printed resin masters to confirm your design before committing to mass production. Contact Lifeng Crafts to discuss your project, and we will send you a free manufacturing recommendation.
