1. Project Overview
Gudetamaorama is a premium hard enamel lapel pin designed as a collectible metal art piece…
“Gudetamaorama” is a custom-designed hard enamel lapel pin developed as a premium collectible item, combining sculptural metalwork, layered enamel coloring, and fine-detail printing. The product was designed to balance visual storytelling with durable construction, targeting collectors who value both aesthetics and craftsmanship.
This project involved multiple production processes, including hard enamel filling, partial printing, transparent sandblast effects, gradient pearl finishes, and gold electroplating. The final pin is sized at approximately 2.5 inches, making it visually prominent while remaining wearable.
The objective of this case was to translate a detailed illustration into a manufacturable metal pin without losing character expression, color depth, or surface hierarchy.
Design Concept & Visual Structure
2. Design Concept & Visual Structure
The visual structure of the pin is built around a layered composition…
The central motif features a seated fairy-like character perched on a dimensional letter block, framed by a circular backdrop. The design intentionally uses vertical depth, separating foreground, midground, and background elements through metal height differences and color contrast.
Key visual decisions include:
Raised metal outlines to preserve character definition
A circular background acting as a visual halo
Letter block geometry providing structural balance
Soft facial expressions offset by bold color accents
This layered composition allows the pin to read clearly from a distance while rewarding close inspection with fine details.
Materials & Manufacturing Techniques
3. Materials & Manufacturing Techniques
The pin is produced using zinc alloy with a target thickness of approximately 2.5 mm. Zinc alloy was selected to support complex internal cuts and layered depth while maintaining structural stability.
Primary manufacturing processes include:
CNC mold creation with internal cutting
Hard enamel filling for solid color areas
Printed detailing for facial features and highlights
Gold electroplating for a warm, premium finish
All samples were approved through a first-article inspection process prior to bulk production, ensuring consistency between artwork and physical output.
Color System & Surface Treatments
4. Color System & Surface Treatments
Color application plays a critical role in this product. The palette combines opaque enamel, transparent effects, and printed gradients to achieve dimensional richness.
Notable treatments include:
Transparent sandblast enamel for light diffusion
Stained-glass style transparent colors with subtle glitter
Gradient pearl powder for iridescent background tones
UV printing for soft blush and facial shading
These finishes were carefully sequenced to avoid contamination between enamel fills and printed layers.
Backside Design & Functional Details
5. Backside Design & Functional Details
The backside of the pin is intentionally minimalist, featuring a sandblasted matte gold surface. Branding text and illustration are recessed to maintain legibility without in
Two rubber clutches are used for attachment, selected for stability due to the pin’s size and weight. The dual-clutch configuration prevents rotation and ensures the pin remains level when worn.
Packaging consists of individual PVC bags with bubble protection to prevent surface abrasion during transit.
Production Challenges & Solutions
6. Production Challenges & Solutions
One of the primary challenges was managing the interaction between printed details and hard enamel surfaces. Printing too early risked distortion during enamel curing, while printing too late reduced adhesion.
The solution involved:
Completing all enamel fills first
Polishing and cleaning the surface
Applying print layers as a final controlled step
Another challenge was maintaining clarity in transparent sandblast areas. This was resolved by adjusting bla

FAQ
Q1: Why combine hard enamel with printing instead of enamel only?
Printing allows for soft gradients, facial expressions, and fine details that are difficult to achieve with enamel alone.
Q2: Is the transparent sandblast effect durable?
Yes. When sealed correctly, transparent sandblast enamel maintains durability comparable to standard hard enamel.
Q3: Why use zinc alloy instead of iron or brass?
Zinc alloy supports deeper internal cuts and layered molding, which are essential for this design’s dimensional structure.
Q4: Can this design be scaled smaller?
Yes, but some printed details may require simplification at smaller sizes.
Conclusion
“Gudetamaorama” demonstrates how thoughtful integration of illustration, material choice, and manufacturing techniques can elevate a lapel pin from a simple accessory to a collectible art object. By combining hard enamel, advanced surface treatments, and precise printing, this project achieves both visual depth and long-term durability.
The case highlights the importance of production planning, especially when multiple finishes and processes intersect. From mold design to final inspection, each stage contributes to preserving the original artistic intent while meeting manufacturing constraints.
This product serves as a strong example of how complex artwork can be successfully translated into metal without sacrificing character, color, or craftsmanship.
