Chanel Classic Perfume Bottle Cap On-Demand Zamak Die Casting Production

Precision Zamak Casting for High-End Cosmetic Packaging

Zamak (zinc-aluminum alloy) is the material of choice for premium packaging parts requiring tactile weight, fine detail reproduction, and smooth finishing. Zamak 3 and Zamak 5 are commonly used for perfume caps due to their excellent flow characteristics and surface definition.

Technical specifications:

• Minimum wall thickness: 1.2 mm

• Casting tolerance: ±0.05 mm (ISO 8062 CT6)

• Surface porosity: <0.3%

• Reproducible edge detail: ≤0.1 mm

The casting process is optimized for low-to-mid volume runs using zinc die casting methods, ensuring cost-efficiency without compromising quality.

Mold Design and Detail Reproduction

To replicate brand-defining geometries, the mold includes:

• Mirror-polished cavity inserts (Ra ≤ 0.4 µm)

• Micro-venting channels for air evacuation

• Controlled fill rate (<0.2 sec) to reduce flow marks

Multiple design variants are supported with interchangeable core inserts. Polishing and deburring are conducted post-ejection to prepare for finishing.

Surface Finishing: Electroplating and Hand Polishing

Perfume cap surfaces must deliver flawless aesthetic appeal. After casting, the parts undergo:

• Vibratory tumbling for edge smoothing

• Manual polishing to achieve mirror gloss

• Electroplating in chrome, gold, or nickel finishes

Performance criteria:

• Plating thickness: 8–12 µm

• Surface roughness post-finish: Ra < 0.05 µm

• Cross-hatch adhesion test: >4B (ASTM D3359)

Optional finishing includes UV coating or matte lacquers. Each finish type is validated through abrasion, salt spray, and humidity tests to meet premium retail standards.

Flexible On-Demand Manufacturing for Short Runs

Luxury goods often require limited production runs, seasonal variants, or personalized product editions. On-demand casting supports:

• Batch sizes from 500 to 10,000 units

• 10-day tooling changeover cycles

• Just-in-time (JIT) delivery models

• Minimal material waste (<5%)

For high-mix, low-volume models, low volume manufacturing offers rapid market response and SKU flexibility without excessive upfront investment.

Inspection and Packaging Standards for Luxury Goods

Each batch of perfume caps undergoes:

• Visual defect classification under 600 lux lighting

• CMM inspection for key feature dimensions

• Plating adhesion and corrosion resistance testing

• Cleanroom packaging with custom velvet-lined trays

Parts are handled using nitrile gloves to prevent fingerprinting, and shipping includes desiccant protection to maintain luster during transit.
