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

Powder compact cases are everyday cosmetic packaging that customers see and touch at close range. Their surface finish must look flawless — smooth and glossy — because the case is part of the product experience. Compact cases are small parts with curved lids, recessed details and thin edges, and they are made in a wide range of colors and designs. Coating such parts consistently by hand is difficult. For manufacturers of powder compact cases, adopting an intelligent automated robotic coating workstation is a practical way to achieve premium, repeatable finishes at production volume.

The Challenge: Cosmetic-Grade Finish on Small Compact Cases

Powder compact cases are produced in many designs, colors and finishes, which makes coating quality hard to stabilize. Factories relying on manual spraying typically struggle with:

• Uneven film on small curved parts: Operators find it difficult to keep a uniform coating across curved lids, recessed details and thin edges, causing thin spots, sagging or runs.
• Color difference between batches and designs: 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 parts: Defects such as orange peel, pinholes and dust marks scrap finished compact cases and inflate production cost.
• Frequent design and color changeover: Cosmetic packaging changes with every product launch, making manual re-tuning time-consuming.

The Solution: Intelligent Automated Robotic Coating on a Ground-Mounted Line

To meet the finishing requirements of powder compact cases, manufacturers can adopt an intelligent automated robotic coating 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 case types, paint system and target output.

Key equipment features applied in this cosmetic coating scenario:

• Automated robotic coating: Stable, repeatable spraying trajectories keep film thickness uniform across curved compact case surfaces and fine details.
• 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.
• Stored programs for quick changeover: The Mansheng touch screen control platform stores 10,000+ coating programs, so parameters for different case designs and colors can be recalled instantly via USB communication.
• Integrated conveyor automation: Seamless belt or roller conveyor with custom length supports continuous flow of compact cases and reduces manual handling.
• 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 intelligent automated robotic coating, powder compact case manufacturers move from operator-dependent finishing to controlled, repeatable coating:

• Smooth, cosmetic-grade finish: Fixed spraying parameters eliminate manual variation, reducing thin spots, sagging and color difference.
• Lower reject rate: Stable film thickness and fewer coating defects mean less scrap of decorated compact cases.
• 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 case designs, for frequent product launches.
