Introduction: To address reduced coating efficiency from aging equipment and the increased workload on operators due to touch-up work, the company introduced new powder coating equipment.
Benefits
1. Paint usage was reduced by 50% and automatic powder coating guns doubled panel productivity while boosting output of other components by 30%.
2. Touch-up work was reduced to less than half, allowing a reduction in personnel from 2 to 1 and achieving significant labor savings.

Introduction: The company provides solvent and powder coating services for general metals and aluminum. Traditionally, powder coating had been applied manually in the same booth used for solvent coating. However, challenges such as coating quality issues, poor working conditions caused by a drying furnace installed directly above the booth, and concerns over potential labor shortages prompted the company to introduce a painting robot. 
Benefits:
1. By establishing a dedicated powder coating line, the company achieved full automation without manual correction, resulting in improved coating quality.
2. The high transfer efficiency of the coating guns allowed for increased conveyor speed, which enhanced productivity and reduced coating material usage by approximately 20%.

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.
