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

A specialized motorcycle components manufacturer located in Chongqing, China's motorcycle manufacturing hub, producing rear frames, swingarms, and subframes for domestic and international motorcycle brands. The company supplies structural components to three major OEMs and maintains an annual output of 200,000+ frame units. As quality standards tightened across the motorcycle industry, the client recognized that their semi-automated coating process could no longer meet the precision and consistency demands of their Tier-1 customers.

The client's existing coating line relied on reciprocating spray machines with limited axis control, creating specific pain points. Complex geometry coating gaps - motorcycle rear frames feature tubular structures, weld joints, and irregular surfaces that the old 3-axis system could not fully cover, requiring manual touch-up on 30% of units. Inconsistent film thickness - without closed-loop feedback, coating thickness varied by +/-15% across different frame sections, affecting corrosion resistance and aesthetic quality. High solvent emissions - poor transfer efficiency of the old spray guns led to excessive paint mist and VOC emissions, raising environmental compliance concerns and material costs.

After a 2-month technical evaluation involving three automation vendors, the client deployed the Mansheng 500X7 Automatic Spray Painting Machine with 7-axis closed-loop stepper drive, specifically configured for large metal structural component coating.

Deployed Configuration:

The 500X7 system was installed as a direct replacement for the old reciprocating spray station within one week. Mansheng's application engineers developed 8 custom spray programs optimized for different frame models, including sequences that trace weld seams and tubular contours with the dual guns working independently on opposite sides of the frame.

Quantified Results (6-Month Post-Implementation):

• First-Pass Yield Improved from 70% to 97.5%: 7-axis control with +/-0.05mm positioning eliminated manual touch-up requirements by achieving complete coverage on complex tubular and weld-joint geometries
• Coating Thickness Uniformity Achieved at +/-3%: Closed-loop stepper drive maintained precise gun-to-surface distance throughout each spray cycle, ensuring consistent film build across all frame sections
• Paint Transfer Efficiency Increased by 42%: The 1.3mm Mansheng Blue Guns with independent oil output control optimized atomization and reduced overspray, directly cutting paint consumption and VOC emissions
• Production Capacity Doubled: Output increased from 600 to 1,200 frame units per shift, with the dual-station rotation design enabling continuous non-stop operation
• Customer Audit Score Rose from B to A+: The client's major OEM customer upgraded their supplier quality rating after the coating consistency improvements were verified in audit

Switching to the Mansheng 500X7 was a strategic decision for our coating line upgrade. The 7-axis precision means we no longer need manual touch-up operators - the machine handles every curve and weld on our rear frames automatically. Our OEM customers noticed the quality improvement immediately, and our paint consumption dropped significantly. The ROI was achieved within 10 months. - Engineering Manager, Chongqing Motorcycle Parts Co.
