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

Spherical plastic toy balls — play balls, playground balls, sport toy balls, novelty balls and kids’ toy spheres — are colorful products whose even, glossy coating is a key part of their appeal. Because a ball is viewed and handled from every direction, its coating must be uniform over the entire spherical surface, with no thin areas, runs or color patches. Coating spheres consistently by hand is notoriously difficult, especially at high production volumes. For toy manufacturers, adopting a robotic high-uniformity spraying module is a practical way to achieve even, repeatable finishes across the whole ball surface.

The Challenge: Uniform Coating on Spherical Plastic Toy Balls

Spherical toy balls are produced in many sizes, colors and designs, which makes coating quality hard to stabilize. Factories relying on manual spraying typically struggle with:

• Uneven film across the spherical surface: Operators find it difficult to keep a uniform coating over the full curved surface of a ball, causing thin spots, runs or color patches.
• 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 balls and inflate production cost.

The Solution: Robotic High-Uniformity Spraying on a Ground-Mounted Line

To meet the finishing requirements of spherical plastic toy balls, manufacturers can adopt a robotic high-uniformity spraying module 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 ball sizes, paint system and target output.

Key equipment features applied in this toy coating scenario:

• Robotic high-uniformity spraying: Stable, repeatable spraying trajectories keep film thickness uniform across the entire spherical surface of each ball.
• 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 balls and reduces manual handling of round parts.
• Stored programs for quick changeover: The Mansheng touch screen control platform stores 10,000+ coating programs, so parameters for different ball sizes 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 robotic high-uniformity spraying, toy manufacturers move from operator-dependent finishing to controlled, repeatable coating:

• Even, glossy finish all around: Fixed spraying parameters eliminate manual variation, reducing thin spots, runs and color patches on ball surfaces.
• Lower reject rate: Stable film thickness and fewer coating defects mean less scrap of finished balls.
• Stable daily output: Production no longer depends on the availability of skilled painters, making delivery schedules reliable.
• Fast size and color changeover: Stored programs allow quick switching between ball sizes and colors, supporting many product lines.
