latest company case about Dongguan Mansheng Automation Equipment Co., Ltd Certifications

Cosmetic makeup glass bottles — foundation bottles, nail polish bottles, serum bottles and perfume bottles — are premium packaging that consumers see on shelves and hold every day. Their coating must be smooth and fine, because the bottle surface is part of the makeup experience and any thin spot, run or color difference is immediately noticeable. Many makeup bottles are small and cylindrical, with curved bodies that demand a fine, even mist coating over the full surface. Achieving this consistently by hand is difficult at high volume. For cosmetics manufacturers, adopting an automated fine-mist spraying workstation is a practical way to achieve premium, repeatable finishes.

The Challenge: Fine, Even Coating on Cosmetic Makeup Glass Bottles

Cosmetic makeup glass bottles are produced in many shapes, sizes and colors, which makes coating quality hard to stabilize. Factories relying on manual spraying typically struggle with:

• Uneven film on small curved bottles: Operators find it difficult to keep a fine, uniform coating across curved bottle bodies, causing thin spots, runs or sagging.
• Color difference between batches: Spray distance, speed and paint feed vary with each operator and session, so the same color can look different between batches.
• High reject rate on decorated packaging: Defects such as orange peel, pinholes and dust marks scrap finished bottles and inflate production cost.
• Frequent color and design changeover: Cosmetic packaging changes with every product launch, making manual re-tuning time-consuming.

The Solution: Automated Fine-Mist Spraying on a Ground-Mounted Line

To meet the finishing requirements of cosmetic makeup glass bottles, manufacturers can adopt an automated fine-mist spraying workstation built on a fully customized, ground-mounted automatic spray painting production line. The conveyor configuration, spray station count and layout are engineered around the customer’s bottle types, paint system and target output.

Key equipment features applied in this glass coating scenario:

• Fine-mist spraying technology: Stable, repeatable spraying trajectories atomize the paint into a fine mist, keeping film thickness uniform across small curved bottle bodies.
• Dual gun stations with closed-loop control: Dual independent guns with stepper drive achieve ±0.05mm positioning accuracy for consistent coating quality on every piece.
• Integrated conveyor automation: Seamless belt or roller conveyor with custom length supports continuous flow of bottles and reduces manual handling.
• Stored programs for quick changeover: The Mansheng touch screen control platform stores 10,000+ coating programs, so parameters for different bottle shapes and colors can be recalled instantly via USB communication.
• Industrial-grade components: Core parts sourced from leading brands such as Leadshine, HIWIN and NSK ensure long-term reliability under continuous production.

Results Manufacturers Can Expect

With automated fine-mist spraying, cosmetics manufacturers move from operator-dependent finishing to controlled, repeatable coating:

• Smooth, fine finish: Fixed spraying parameters eliminate manual variation, reducing thin spots, runs and color difference on bottle surfaces.
• Lower reject rate: Stable film thickness and fewer coating defects mean less scrap of decorated bottles.
• Stable daily output: Production no longer depends on the availability of skilled painters, making delivery schedules reliable.
• Fast design and color changeover: Stored programs allow quick switching between bottle designs, supporting frequent product launches.
