Project Overview
The Snape & Charlie hard enamel lapel pin is a premium collectible developed as part of a limited edition series. With a finished size of 2.5 inches, this pin was intentionally designed larger than standard lapel pins to accommodate a detailed narrative illustration and create a strong visual presence.
The project required translating a complex, emotionally driven artwork into metal while preserving character expression, color depth, and fine line detail. To achieve this, multiple production techniques were combined, including hard enamel filling, printed detail layers, and gold electroplating.
This case study documents how illustration, material selection, and manufacturing control were aligned to produce a durable, high-end collectible suitable for both wearing and long-term collection.
Product Positioning and Use Case
This product was positioned as a collector-focused lapel pin rather than a mass-market accessory. The larger size, complex color system, and custom backstamp clearly signal its limited edition status.
Such pins are commonly used for brand collaborations, fan-oriented merchandise, event exclusives, and story-driven product lines. In this case, the emphasis was placed on emotional storytelling and visual richness, making the pin suitable for display as well as wear.

Artwork and Color System Analysis
The front design incorporates a highly controlled color system consisting of standard solid enamels, pearlescent enamels, and transparent sandblast enamel. Each enamel type was selected based on the visual role it plays within the illustration.
Solid hard enamel was used for primary character shapes and background elements to ensure color stability and surface durability. Pearlescent enamels were applied selectively to introduce subtle highlights and depth, enhancing the overall dimensionality of the artwork.
Transparent sandblast enamel was used to allow underlying metal texture to interact with color, adding visual interest without overwhelming the main illustration. Gold metal lines function as both visual separators and structural barriers, ensuring clean color boundaries during filling.
Printed layers were added after enamel curing to reproduce fine details such as facial expressions, shadows, and tonal transitions that cannot be achieved through enamel alone.
Manufacturing Process Breakdown
Manufacturing began with CNC mold creation based on finalized vector artwork. Line thickness, corner angles, and enamel cell depth were carefully adjusted to balance visual accuracy with production feasibility.
After stamping and trimming, the pin bases underwent gold electroplating followed by surface polishing. Hard enamel colors were then hand-filled, cured at high temperature, and polished flat to achieve a smooth, glass-like finish.
Screen printing was applied as a secondary process to add fine details and gradients. Once printing was completed, attachments were installed and each piece was prepared for inspection.
Backstamp and Structural Details
The back of the pin features a fully customized backstamp including text, decorative elements, and brand identification. The backstamp layout differs from other products in the same collection, reinforcing its unique edition status.
Two pin posts were strategically placed to distribute weight evenly and prevent rotation during wear. This structural decision is particularly important for pins exceeding standard size and weight thresholds.
Quality Control and Packaging
Quality control was implemented throughout production, beginning with digital artwork approval and color confirmation. A first article sample was reviewed to verify plating quality, enamel smoothness, and print alignment.
Final inspection included a visual check of every pin to ensure consistent color fill, clean metal lines, and secure attachment installation. Each pin was individually packaged in a PVC bubble bag to protect the surface during shipping and storage.
Production Challenges and Solutions
One of the primary challenges involved maintaining color consistency across multiple enamel types, particularly pearlescent and transparent fills. This was addressed through controlled test fills and curing adjustments.
Another challenge was achieving accurate print alignment on a curved enamel surface. Custom positioning fixtures were used during printing to ensure precise placement of fine details.

Conclusion
The Snape & Charlie hard enamel lapel pin exemplifies how detailed illustration and advanced manufacturing techniques can be combined to create a premium collectible product. Through careful planning of materials, color systems, and production workflow, the final result achieves both visual depth and long-term durability.
This case demonstrates best practices for transforming complex artwork into metal form, making it a valuable reference for future limited edition pin projects and custom collectible development.
