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

Cultural and stationery products — pen barrels, pencil cases, storage boxes, desk organizers, gift items and decorative accessories — are everyday items whose color and surface quality directly influence buying decisions. A smooth, uniform finish makes these products look attractive on the shelf. However, stationery products come in a huge variety of shapes, sizes and colors, and many are small parts with curved bodies. Coating them consistently by hand is difficult. For manufacturers of cultural and stationery products, adopting an automated surface finishing workstation is a practical way to achieve stable coating quality at production volume.

The Challenge: Consistent Surface Finishing on Cultural and Stationery Products

Cultural and stationery products are produced in many styles, colors and frequent seasonal updates, which makes coating quality hard to stabilize. Factories relying on manual spraying typically struggle with:

• Uneven film on varied shapes: Operators find it difficult to keep a uniform coating across curved bodies, small parts and fine details, causing thin spots, sagging or runs.
• 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 parts: Defects such as orange peel, pinholes and dust marks scrap finished products and inflate production cost.
• Frequent changeover between product styles: Many SKUs and seasonal design updates make manual re-tuning time-consuming.

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

To meet the finishing requirements of cultural and stationery products, manufacturers can adopt an automated surface finishing 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 product range, paint system and target output.

Key equipment features applied in this surface finishing scenario:

• Automated surface finishing: Stable, repeatable spraying trajectories keep film thickness uniform across curved bodies and fine details of stationery products.
• 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 product styles and colors can be recalled instantly via USB communication.
• Integrated conveyor automation: Seamless belt or roller conveyor with custom length supports continuous flow and reduces manual handling of parts.
• 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 surface finishing, cultural and stationery product manufacturers move from operator-dependent finishing to controlled, repeatable coating:

• Smooth, attractive 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 finished products.
• Stable daily output: Production no longer depends on the availability of skilled painters, making delivery schedules reliable.
• Flexible style changeover: Stored programs allow quick switching between product styles, for many SKUs.
