From a customer’s artwork to a finished metal product, custom manufacturing involves far more than simply creating a mold and casting metal. Every project has its own requirements for dimensions, materials, relief, plating, enamel, attachments, packaging, and quality control.
At ChallengeCoinBadges, we manufacture custom medals, challenge coins, police badges, military badges, lapel pins, keychains, cufflinks, and other metal products for organizations, brands, event companies, distributors, and institutional buyers.
With 20+ years of custom metal manufacturing experience and a team of 100+ employees, our production process is designed to turn customer artwork or concepts into manufacturable products while controlling quality at each stage.
This article explains how a typical custom metal product moves from artwork to engineering, tooling, production, finishing, inspection, and packaging, as well as where these products are commonly used.
1. The Process Starts With Customer Artwork
Every custom project begins with a design.
Customers may provide:
- AI or EPS vector artwork
- PDF files
- CAD drawings
- PNG or JPG images
- Existing product samples
- Sketches
- Logos
- Written design concepts
The artwork does not have to be perfect before contacting the manufacturer.
For example, a customer may provide a simple concept showing:
A department logo + organization name + year + 3D center emblem
The engineering team can then determine how the concept should be converted into a manufacturable metal product.
Why Artwork Preparation Matters
A design that looks excellent on a computer screen may not automatically work as a physical metal product.
The manufacturer may need to adjust:
- Extremely thin lines
- Small lettering
- Narrow gaps
- Tiny enamel areas
- Relief depth
- Border thickness
- Sharp corners
These adjustments are not intended to change the customer’s design concept. They are intended to make the design physically manufacturable and visually clear.
2. Engineering Review Before Tooling
After receiving the artwork, the engineering team evaluates the design.
This is one of the most important stages because a mistake discovered after tooling can create unnecessary delays and costs.
The engineering review may include:
Dimensions
- Diameter
- Length
- Width
- Thickness
Structure
- 2D
- 3D
- Multi-level relief
- Recessed areas
- Raised areas
Colors
- Soft enamel
- Hard enamel
- Multiple colors
- Plating combinations
Attachments
- Pin
- Clutch
- Screw-back
- Magnet
- Key ring
- Ribbon
Text
The team checks whether the lettering can be reproduced clearly at the selected product size.
3. Choosing the Right Metal
The material is selected according to the product’s design, application, production method, and budget.
Common materials include:
Zinc Alloy
A popular choice for complex 3D designs.
It is particularly suitable for:
- 3D challenge coins
- Sculpted badges
- Detailed emblems
- Multi-level designs
Brass
Brass is widely used for:
- Challenge coins
- Medals
- Lapel pins
- Traditional badges
Copper
Copper can provide a distinctive premium metal appearance and is suitable for certain detailed products.
Iron
Iron is often considered for cost-sensitive projects and certain badge or promotional applications.
There is no universal “best” material.
The correct choice depends on the relationship between:
Design + Size + Thickness + Production Method + Finish + Quantity + Budget
4. Creating the Mold
Once the design and engineering specifications are approved, tooling can begin.
The mold determines important physical characteristics of the finished product, including:
- Shape
- Relief
- Borders
- Recessed areas
- Raised details
- Text
- Logo structure
For a simple 2D product, tooling may be relatively straightforward.
A complicated 3D challenge coin can require considerably more engineering because the mold must reproduce different levels of relief and sculpted details.
2D vs. 3D Manufacturing
2D products generally emphasize flat artwork, borders, text, and enamel.
3D products introduce depth, sculpting, raised surfaces, and recessed areas.
For example, a firefighter challenge coin may contain:
- A raised firefighter helmet
- A recessed background
- A raised Maltese cross
- Department lettering
- Antique plating
Each element needs to be considered during tooling.
5. Metal Forming
After tooling is completed, the metal product enters the forming stage.
Depending on the product, manufacturing may involve:
- Stamping
- Die casting
- Molding
- Cutting
- CNC machining
- Other forming processes
Stamping
Often used for products with relatively flat structures.
Typical applications include:
- Lapel pins
- Simple medals
- Flat badges
- Certain challenge coins
Die Casting
Useful for more complicated three-dimensional products.
Applications include:
- 3D challenge coins
- Sculpted badges
- Complex emblems
- Decorative metal products
The production method is selected according to the product structure rather than applying one process to every project.
6. Removing Burrs and Improving the Surface
Freshly formed metal products are not necessarily ready for plating.
They may require:
Deburring → Grinding → Polishing → Surface Preparation
This stage is important because the surface condition directly affects the final appearance.
The production team checks for:
- Burrs
- Sharp edges
- Casting marks
- Scratches
- Uneven surfaces
- Surface imperfections
For a product with a highly polished finish, surface preparation becomes especially important.
7. Polishing
Polishing can dramatically change the appearance of a custom metal product.
Depending on the design, different areas may require different surface treatments.
For example, a challenge coin may combine:
- Polished raised metal
- Antique recessed areas
- Matte sections
- Colored enamel
This combination creates visual contrast between different parts of the design.
For a police badge, polishing can help emphasize the raised lettering and central emblem.
For a medal, polishing can create a cleaner appearance around the main design.
8. Plating and Surface Finishing
After the metal surface has been prepared, the product can receive its selected finish.
Common options include:
- Gold
- Silver
- Nickel
- Black nickel
- Antique gold
- Antique silver
- Antique bronze
- Copper
- Dual plating
Bright Finish
Creates a clean, reflective appearance.
Antique Finish
Darkens recessed areas and emphasizes raised details.
Dual Finish
Combines different metal colors to create contrast.
For example:
Antique silver + gold plating
can make the central emblem visually stand out from the surrounding metal.
9. Adding Soft Enamel or Hard Enamel
Color is another major part of custom metal manufacturing.
Soft Enamel
The enamel sits slightly below the surrounding metal borders.
It creates a textured surface and strong contrast between metal and color.
Common applications include:
- Lapel pins
- Challenge coins
- Police pins
- Military insignia
- Promotional products
Hard Enamel
Hard enamel is filled to the metal borders and polished to create a smoother surface.
It is commonly selected for:
- Premium challenge coins
- Corporate pins
- Recognition products
- High-end commemorative products
The choice depends on the customer’s desired appearance, budget, and application.
10. Manufacturing Custom Medals
Custom medals require several additional considerations because they are frequently produced for events.
A medal may include:
- Front artwork
- Back artwork
- 2D or 3D relief
- Plating
- Enamel
- Ribbon
- Ring
- Custom packaging
Custom medals are widely used for:
- Marathons
- Running races
- Soccer tournaments
- Basketball competitions
- Swimming events
- School competitions
- Academic recognition
- Military ceremonies
- Corporate awards
- Anniversary events
- Charity events
- Employee recognition
For large sporting events, production consistency is especially important because participants expect the same medal design and finish.
11. Manufacturing Custom Challenge Coins
Challenge coins are among the most versatile custom metal products.
A coin can be:
- 2D

The ability to combine different relief levels, finishes, colors, and edge designs makes challenge coins highly customizable.
12. Manufacturing Custom Police Badges
Police badges require especially careful artwork and production review because they represent an organization.
A custom police badge may include:
- Department name
- Department emblem
- Rank
- Badge number
- State or city reference
- Eagle or other symbol
- Custom border
- Plating
- Attachment system
Custom police badges can be produced for:
- Police departments
- Sheriff organizations
- Security organizations
- Law-enforcement associations
- Retirement presentations
- Recognition programs
- Commemorative events
- Training organizations
- Historical displays
For official-use products, the customer should verify that all names, symbols, ranks, and badge numbers have been approved by the relevant organization before production.
13. Quality Control During Production
Quality control does not happen only at the end.
A reliable production process checks different characteristics at different stages.
Artwork Stage
Check:
- Logo
- Text
- Dimensions
- Colors
- Structure
Tooling Stage
Check:
- Relief
- Mold details
- Borders
- Text
- Design proportions
Metal Production
Check:
- Dimensions
- Surface
- Casting/stamping quality
- Weight where applicable
Finishing
Check:
- Plating
- Color
- Enamel
- Polishing
Assembly
Check:
- Pins
- Clutches
- Ribbons
- Rings
- Attachments
Final Inspection
Check:
- Appearance
- Quantity
- Packaging
- Product consistency
14. How Quality Data Can Affect Large Orders
Consider a hypothetical order of 10,000 custom medals.
| Hypothetical Defect Rate | Potentially Defective Pieces |
|---|---|
| 5% | 500 |
| 3% | 300 |
| 2% | 200 |
| 1% | 100 |
| 0.5% | 50 |
| 0.1% | 10 |
The difference between a hypothetical 3% and 0.5% defect rate is 250 pieces.
This illustrates why quality control becomes increasingly important as order quantities increase.
These figures are mathematical examples rather than a claim about ChallengeCoinBadges’ actual defect rate.
15. Inspection Before Packaging
Before products are packed, the production team should verify the finished appearance.
Typical checks include:
Medal
- Correct size
- Correct artwork
- Plating
- Enamel
- Ribbon
- Attachment
Challenge Coin
- Diameter
- Thickness
- Relief
- Front/back artwork
- Plating
- Enamel
- Edge
Police Badge
- Shape
- Logo
- Department name
- Number
- Plating
- Attachment
If the product does not meet the approved specification, corrective action should be taken before shipment.
16. Packaging and Shipment
Packaging protects the products after manufacturing.
Depending on the project, options may include:
- Individual polybags
- Backing cards
- Plastic boxes
- Gift boxes
- Foam inserts
- Presentation cases
Packaging requirements often depend on the application.
For example:
Sports medals: individual protection + ribbon organization
Premium challenge coins: presentation box or protective case
Police badges: protective individual packaging
Retail products: branded packaging and barcode labels
The objective is to make sure the product reaches the customer in the same condition in which it left the factory.
17. From Prototype to Mass Production
A typical custom project can be viewed as five major phases:
Phase 1 — Design
Customer provides artwork or concept.
Phase 2 — Engineering
Factory evaluates manufacturability and prepares production specifications.
Phase 3 — Tooling & Sample
Mold is created and a physical sample is produced.
Phase 4 — Mass Production
Approved specifications are transferred into production.
Phase 5 — Finishing & Delivery
Products receive plating, enamel, assembly, inspection, packaging, and shipment.
This workflow helps reduce misunderstandings because each stage has a clear purpose.
18. What Makes a Custom Metal Manufacturer Reliable?
When comparing manufacturers, buyers should look beyond price.
Consider:
Manufacturing Experience
How long has the factory produced custom metal products?
Engineering
Can the factory identify problems in the artwork?
Equipment
Does the factory have the appropriate production capabilities?
Finishing
Can it provide the required plating and enamel?
Quality Control
Are inspections performed throughout production?
Communication
Can the team explain technical issues clearly?
Production Capacity
Can the factory handle your required quantity?
OEM/ODM Capability
Can the manufacturer work from either finished artwork or an initial concept?
A factory’s ability to communicate manufacturing limitations can be just as important as its equipment.

24. Final Thoughts
A custom metal product is the result of many individual manufacturing decisions.
The process begins with:
Customer Artwork
and develops through:
Engineering → Tooling → Metal Forming → Polishing → Plating → Enamel → Assembly → Quality Control → Packaging
For custom medals, challenge coins, and police badges, the manufacturing process must also reflect the intended application.
A marathon medal needs reliable ribbon attachment and consistent event artwork.
A military challenge coin needs accurate insignia, strong relief, and consistent finishing.
A police badge requires careful attention to organizational details, lettering, numbers, shape, and attachment.
Corporate products may place greater emphasis on branding, packaging, and premium presentation.
