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

IMLUCKY Machinery offers specialized inner wall spray painting machines for glass bottles. Our technology supports a minimum inner diameter of 5mm—perfect for Perfume bottles, medicine bottles, essential oil bottles, cosmetic bottles, thermos bottles, water bottles, and laboratory glassware.

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

  Standard spraying equipment often fails when dealing with narrow-neck containers. Our customers usually face:

  • Access Limitations: Bottles with openings as small as 5-10mm are impossible for standard nozzles to enter, leaving the bottom uncoated.

  • Paint Accumulation & Sagging: Poor airflow inside narrow bottles leads to paint pooling at the bottom or uneven "running" marks on the sides.

  • High Defect Rates: Manual or imprecise coating results in inconsistent transparency and color, which is unacceptable for luxury perfume or pharmaceutical brands

2. Our Specialized Solution (The Innovation)

We have engineered a specialized system to overcome the limits of micro-diameter coating:

• Ultra-Slim Needle Nozzle: Our proprietary spray lance is designed to enter openings with a minimum inner diameter of 5mm, ensuring the coating starts from the very bottom.

• Synchronized Rotary System: The bottle rotates at a precise speed while the nozzle performs a controlled vertical stroke, achieving a 360° uniform finish without dead zones.

• Advanced Atomization Control: High-precision pressure regulation prevents "paint bounce-back," ensuring a smooth, mist-free application even in confined spaces.

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.

• We provide customized nozzle lengths based on your bottle height
