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

Cosmetic glass containers — cosmetic bottles and jars, perfume bottles and flacons, serum and lotion containers, and essential oil bottles — are premium packaging that consumers see on shelves and hold every day. Their coating must be smooth and even, because the container surface is part of the product experience and any thin spot, run or color difference is immediately noticeable. Cosmetic glassware comes in many shapes and sizes, from tall slim bottles to wide jars, and finishing it consistently at high volume is difficult by hand. For cosmetics packaging manufacturers, adopting a high-efficiency automated surface finishing unit is a practical way to achieve premium, repeatable finishes across a mixed product range.

The Challenge: Efficient, Even Finishing on Cosmetic Glass Containers

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

• Uneven film on curved containers: Operators find it difficult to keep a uniform coating across round bodies, shoulders and necks, 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 glassware: Defects such as orange peel, pinholes and dust marks scrap finished containers and inflate production cost.
• Slow changeover across a mixed range: Switching between bottles, jars and flacons of different sizes makes manual re-tuning time-consuming.

The Solution: High-Efficiency Automated Surface Finishing on a Ground-Mounted Line

To meet the finishing requirements of cosmetic glass containers, manufacturers can adopt a high-efficiency automated surface finishing unit 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 container range, paint system and target output.

Key equipment features applied in this glass finishing scenario:

• High-efficiency automated finishing: Fast, stable spraying trajectories finish each container evenly and keep the line moving at production volume.
• 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 mixed container sizes and reduces manual handling.
• Stored programs for quick changeover: The Mansheng touch screen control platform stores 10,000+ finishing programs, so parameters for different container 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 high-efficiency automated surface finishing, cosmetics packaging manufacturers move from operator-dependent finishing to controlled, repeatable coating:

• Smooth, premium finish: Fixed spraying parameters eliminate manual variation, reducing thin spots, runs and color difference across the container range.
• Lower reject rate: Stable film thickness and fewer coating defects mean less scrap of decorated glassware.
• Stable daily output: Production no longer depends on the availability of skilled painters, making delivery schedules reliable.
• Fast changeover across sizes: Stored programs allow quick switching between bottles, jars and flacons, supporting mixed production.
