Custom Hard Enamel Pins | Direct Factory Manufacturer

Description :

Mirror-flat flush surface with authentic jewelry hand-feel. Every hard enamel fill cures rock-solid before running through multi-stage Carborundum flat-stone wet lapping. Raised metal containment borders and hardened enamel colors are leveled onto an identical optical plane, creating a glass-smooth surface that feels completely flat under a thumb.
Dense H65 brass metallurgy and scratch-resistant 3H hardness. Stamped from dense H65 brass (8.4-8.5 g/cm³) rather than porous lightweight castings. The cured mineral resin reaches 3H to 4H hardness, resisting surface fingernail scratches, everyday fabric abrasion, and 48-hour ASTM B117 neutral salt spray without clouding or peeling.
Rapid 2-4 working hours proofs and 2-year free die retention. Receive fully dimensioned 3D CAD engineering proofs specifying exact 0.35 mm metal containment borders within 2 to 4 working hours. Your hardened steel coining dies stay cataloged in climate-controlled storage for 2 full years with $0.00 die fees on future reorders.

Hard Enamel (Flush Cloisonné) vs. Soft Enamel (Recessed Relief)

Choosing between hard enamel and soft enamel is the most decisive aesthetic choice in custom pin manufacturing. While both utilize precision-tooled metal dies, their finishing order dictates touch, visual reflection, and structural longevity.

• Synthetic Hard Enamel (Featured)

Best for: Corporate executive pins, luxury fashion branding, high-end anime and gaming collector merch, and commemorative milestone crests.

Completely flush mirror-flat surface: Overfilled enamel resin is hand-stoned level with metal boundary walls, producing a continuous glass-like plane that catches clean linear highlights without trapping dirt.
Scratch-resistant jewelry durability: Baked at 160°C to 200°C and wet-lapped to 3H-4H hardness, the face resists abrasive fabric wear on bags, suits, and denim jackets without requiring an epoxy dome.
Crisp geometric separation: Polished flush metal lines provide sharp visual borders, lending formal authority to intricate corporate logos and collector crests.

• Traditional Soft Enamel (Recessed Relief)

Best for: Event giveaways, sports team trading pins, band merchandise, and illustrations with fine 0.25 mm metal line details Custom Soft Enamel Pins.

Tactile three-dimensional relief: Color sits recessed below raised metal rims, providing an unmistakable dimensional texture that can be traced with fingertips.
Tighter line tolerances: Because soft enamel skips aggressive stone-lapping, metal lines can hold as thin as 0.25 mm (0.010″) for highly detailed artwork.
Commercial volume efficiency: Eliminating the hand wet-grinding stage makes soft enamel the cost-efficient choice for 500 to 50,000+ piece runs.

💡 Practical Craft Selection Tip: Select Hard Enamel when your design demands a flush, jewelry-grade polish that will not snag on clothing or dull over years of daily wear. Choose Soft Enamel when you want an unmistakable textured 3D ridge feel, thinner 0.25 mm metal outlines, or lower unit costs on high-volume promotional runs.

From Concept to Creation: Direct-Factory Production & Quality Assurance

1. High-Tonnage Hydraulic Coining	Master CNC-engraved steel dies stamp solid H65 brass blanks under 300 to 500 tons of hydraulic pressure, coining crisp 0.35 mm containment lines.
2. Perimeter Die Trimming & Post Brazing	Hardened punch dies trim outer flash while brass spur pins are silver-brazed onto the reverse face under calibrated 5.0 kgf shear testing.
3. Hand-Applied Overfill Enamel Dispensing	Mineral resin pigments mixed to Pantone PMS Solid Coated are manually dispensed with micro-needles, intentionally overfilling each metal cell.
4. Thermal Oven Curing	Racked badges bake in conveyorized ovens between 160°C and 200°C, polymerizing the enamel resin into a durable solid with 3H-4H hardness.
5. Carborundum Flat-Stone Wet Lapping	Medals pass across continuous water-lubricated stone wheels, grinding excess enamel down until color and metal share a single flush plane.
6. Final Mirror Buffing & Galvanic Plating	Badges undergo multi-stage sisal and cotton wheel buffing before entering rack electroplating to apply 24K gold or nickel over the flush metal rims.

Director of Quality & Engineering, Gold Valley Manufacturing: Every production run of custom hard enamel pins is audited against strict jewelry-grade benchmarks. From raw H65 brass spectrographic validation to 100% surface planar inspection under 10x optical magnification, our Dongguan manufacturing facility operates in strict compliance with Disney FAMA (Facility ID: FAC-086164) and NBCUniversal technical standards.

Custom Hard Enamel Pins: Ordering & Production FAQ

What is the minimum order quantity (MOQ) for custom hard enamel pins?

A: Our production standard starts at 100 pieces per custom mold design, making it accessible for corporate anniversaries, independent illustrators, and boutique retail brands. Volume tiered discounts apply automatically at 300, 500, 1,000, and 5,000+ units, significantly reducing per-unit tooling amortization.

Why do hard enamel pins require wider metal lines than soft enamel?

A: Because hard enamel pins undergo aggressive flat-stone wet grinding to level the hardened resin flush with the metal walls. Raised metal borders must be designed at a minimum of 0.35 mm (0.014″) wide to withstand stone friction without collapsing. If your artwork contains ultra-fine lines below 0.30 mm, contact our engineering team to review whether localized soft enamel or screen-printed overlays are better suited.

Do hard enamel pins require an epoxy dome coating to protect the surface?

A: No. Hard enamel achieves a durable 3H to 4H surface hardness through thermal baking at 160°C to 200°C. The stone-polished mineral resin is naturally scratch-resistant and will not yellow, haze, or soften over time like organic epoxy domes. Adding an epoxy coating over hard enamel is neither necessary nor recommended.

How quickly will we receive digital proofs, and can we revise Pantone colors?

A: After you submit vector artwork (.AI, .EPS, .PDF, or .SVG), our engineering team returns fully dimensioned 3D CAD production proofs within 2 to 4 working hours. Proofs clearly annotate exact metal plating finishes, line thicknesses, Pantone PMS color swatches, and clutch placements. Revisions are updated same-day until your team formally signs off.

How long are custom coining dies archived for future repeat orders?

A: All hardened steel dies are numbered and cataloged in our climate-controlled warehouse for 2 full years following your most recent production run. Placing repeat orders within this 2-year window incurs a $0.00 tooling fee. When you plan repeat production, submit your project specifications with your previous PO number for immediate production scheduling.

Can we inspect a physical pre-production sample before full mass stamping?

A: Yes. Following digital 3D proof approval, we produce physical pre-production counter-samples within 5 to 7 working days. High-resolution multi-angle macro photos and video inspections are shared immediately, or physical samples can be dispatched via international express (DHL/FedEx) for hands-on review prior to mass manufacturing.
