First: Clarify requirements and design

1：Determine the use

       ①The use determines the material, size and process (e.g., precious metals may be used for commemorative coins, wear-resistant alloys for game coins, and promotional coins may be more cost-conscious).

       ②Whether additional features are required (e.g. magnetic attraction, anti-counterfeit marking, numbering, etc.).

2：Design Pattern

       ①Double-sided pattern: Both sides can be customized with pattern, text, logo, high-definition vector drawing (such as AI, CDR format) is required.

       ②Size and thickness: common diameter 30-70mm, thickness 3-5mm (adjusted according to material and usage).

       ③Edge design: glossy edge, toothed edge, engraved edge, etc. (e.g. non-slip toothed edge common for coins).

3：Select Material

       ①Metallic materials: copper, zinc alloy, stainless steel, iron, silver, gold (in ascending order of cost).

       ②Non-metallic materials: ABS plastic, acrylic, epoxy resin (suitable for low-cost or lightweight needs).

       ③Surface technology: electroplating (gold, silver, bronze), antique, color printing, embossed effect, etc.


Second: Choosing a customized manufacturer

1: Finding suppliers

      ①Contact professional mint-we are specialized in customized double-sided coins, medals, keychains and so on.

      ②Prefer makers with experience in making and view cases.

2: Communication and proofing

      ①Provide the design, confirm the material, size and process details.

      ②Check the pattern clarity, material texture, etc. of the samples.

3: Confirm order details

      ①Quotation: Calculated according to the material, quantity and complexity of the process (MOQ is usually more than 100-          1000pcs).

      ②Delivery time: generally 7-15 days (may be extended for complex processes or large quantities).

      ③Contract: Clearly define the quality requirements, acceptance standards, payment methods and after-sales terms.

Third: The production process

1: Mold making

      ①Use a carving machine or 3D printing to create steel molds to ensure pattern accuracy and detail.

2: Material Processing

      ①Metal material: molding by stamping and die-casting; plastic material: injection molding.

3: Surface treatment

      ①Plating, spraying, laser engraving, color printing and other processes to enhance the visual effect.

      ②Add special coating (e.g. anti-oxidation, anti-scratch).

4: Quality inspection and packaging

      ①Manufacturer conducts sampling inspection on appearance, size and weight.

      ②Packaging: bulk, plastic, gift box (customized boxes are available)

Fourth: Precautions

1: Copyright and Law

      ①Ensure that the design pattern does not infringe the intellectual property rights of others, especially the corporate logo           or art pattern.

      ②If used in circulation scenarios (e.g. tokens), they need to comply with local laws and regulations.

2: Budget Control

      ①Material and process are the main cost factors, zinc alloy is cost-effective, and precious metals (e.g. silver) are suitable               for high-end needs.

      ②The larger the quantity, the lower the unit price.

3: Acceptance Criteria

      ①Upon receipt of large shipment, check for defects (e.g. pattern misalignment, plating off, edge burrs).

Fifth: Frequently Asked Questions

Q: What is the minimum order quantity?

A: Usually the minimum order is 100-1000 coins, small batch customization is more costly.

Q: Can you make shaped coins (not round)?

A: Yes, but the mold cost is higher and the production cycle is longer.

Q: How long is the customization cycle?

A: 7-10 days for simple process, complex process (such as color printing + embossing) may take 15-30 days.
