Automatic Inside Spray Painting Machine for Perfume Bottles | Min. 5mm Neck & Dual-Gun Design

Automatic inner wall spray coating machine for 5mm diameter glass bottles

• Ultra-Small Opening Compatibility: Breaking industry limits, automatic internal spraying available for bottlenecks as small as 5mm.
• Zero Dead Zones on Bottle Shoulders: Dual guns with precisely calculated angles solve the challenges of irregular-shaped bottles.

• High Consistency: Mechanical operation eliminates color differences and uneven coating thickness.

• 1. Challenges in the Industry (The Pain Points)

• Narrow bottlenecks: Standard spray nozzles cannot enter, resulting in uneven inner-wall coating.
• Shoulder dead zones: The shoulder area of bottles often goes uncoated, leading to low yield rates.
• Low efficiency: Manual internal spraying is not only slow but also causes severe paint waste and large atomized particles.

• Difficult cleaning: Internal spraying components are extremely hard to maintain and clean.

2. Our Specialized Solution (The Innovation)

• Ultra-fine nozzle technology: Specially designed for small openings, compatible with bottlenecks as small as 5mm, for precise internal spraying.

• Dual-gun full coverage: Unique dual-gun switching & linkage design to eliminate dead zones on bottle shoulders and achieve full 360° coverage.

• Precision control system: Ensures even distribution of every drop of paint on the inner wall, reducing paint consumption by over 30%.

3. Real Results for Your Business (The Value)

• Zero-Defect Production: Boost your yield rate from 60% to over 98%, meeting the highest quality standards for luxury packaging.

• 25% Paint Savings: Precision targeting reduces overspray and material waste compared to traditional "flood" coating methods.

• Mass Production Ready: Fully automated cycles allow for high-volume output (thousands of units per day), replacing 3-5 manual operators.
