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

Client Background

A mid-scale plastic toy manufacturer based in Guangdong, China, specializing in sports-themed toys including footballs, basketballs, and other spherical products. The client produces over 500,000 toy footballs annually for export markets across Europe, North America, and Southeast Asia. With rapidly growing order volumes and increasingly strict quality requirements from international buyers, the client's existing manual spray painting process had become a critical bottleneck in their production line.

The Challenge

The manufacturer faced three core issues with their previous manual spraying operation. First, inconsistent coating quality - manual operators could not maintain uniform paint thickness on spherical surfaces, resulting in an unacceptable 12% defect rate and frequent customer complaints. Second, low production throughput - each football required approximately 45 seconds of manual spraying, capping daily output at 800 units per shift. Third, rising labor costs and worker safety concerns - spray painting operators required extensive training, and prolonged exposure to paint fumes posed occupational health risks despite personal protective equipment.

The Solution: Mansheng 500X7 7-Axis Auto Spray Machine

After evaluating multiple automation suppliers, the client selected the Mansheng 500X7 Automatic Spray Painting Machine, a 7-axis closed-loop stepper-driven coating system specifically engineered for complex 3D surface spraying. The machine was deployed on the client's toy football production line in Q2 2025.

Implementation and Results

The 500X7 machine was integrated into the existing production line within 3 working days. Mansheng's engineering team pre-programmed 12 distinct spraying sequences tailored to different football sizes and paint specifications. The dual-station rotation design allows continuous operation - while one station sprays, the operator loads/unloads the other, eliminating idle time.

Quantified Results (3-Month Post-Implementation):

• Defect Rate Reduced by 91%: From 12% to under 1.1%, achieved through +/-0.05mm positioning accuracy and 360-degree high-speed rotation ensuring uniform coverage on spherical surfaces
• Production Throughput Increased by 375%: Daily output rose from 800 to 3,800 units per shift, enabled by the 500mm x 500mm large spray range handling multiple footballs simultaneously
• Labor Cost Savings of 62%: Reduced manual spray operators from 6 to 2 (loading/unloading only), with remaining staff reassigned to higher-value quality inspection roles
• Paint Consumption Reduced by 28%: Precision spray control and independent dual-gun oil output eliminated overspray waste common in manual operations
• Energy Cost at 0.95KW/H: Ultra-low power consumption minimized operational expenses while maintaining industrial-grade output

Client Feedback

The 500X7 machine transformed our toy football coating process completely. We used to struggle with inconsistent paint finishes and high rejection rates. Now our defect rate is below 1.1%, and our European buyers have complimented the improved coating consistency. The machine paid for itself within 8 months through labor savings alone. - Production Director, Guangdong Toy Manufacturer
