Introduction To resolve issues caused by aging coating guns on its two-component coating line, such as declining quality, reduced productivity, and environmental concerns, the company upgraded its coating equipment and facilities.　
Benefits
1. The use of base resin and hardener, along with the amount of waste generated, was reduced by 15%.
2. Improvements in coating efficiency enabled an increase in line speed by 0.2 m/min.
3. The combination of highly efficient automatic coating guns and a multi-color two-component mixing system capable of high-quality coating created a synergistic effect, achieving both cost reduction and productivity improvement.

Introduction : Due to the aging of the automatic coating system for topcoat, the reciprocating and automatic spray guns were updated.
Benefits :
1. The coating quality has improved significantly.
2. The high coating efficiency of the automatic spray gun improved productivity and reduced paint usage by 10%.
3. Corrective coating and maintenance work have been significantly improved, reducing the burden on workers.
4. By maximizing the spray gun's performance, it is expected that paint usage will be further reduced.

Introduction : Introduced the hand spray coating for the undercoat and an automated system for the topcoat. Due to the contribution of the automated system to improved productivity and stable coating quality, the same system was introduced for the undercoat one year later.
Benefits :
1. The amount of work per hanger has increased, improving productivity by 1.5 times.
2. Paint usage was reduced by 10%.
3. Automation has reduced the number of workers required and ensured 100% compliance with the standard film thickness.
