Introduction : Due to the aging of workers and the deterioration of coating machines, the issue of quality/delivery time became apparent. In addition, existing facilities and personnel are no longer capable of responding to increased demand, and the coating facility has been renewed.
Benefits :
1. Productivity doubled.
2. The defect rate reduced to nearly zero.
3. The amount of paint used decreased by 40% in terms of the purchase value.
4. The proportion of robotic painting has increased to 90%, and hand sprays are now limited to small lot products, significantly reducing the burden on workers.

Introduction : Automatic guns and control systems were updated as coating machines became obsolete.
Benefits :
1. The high-efficiency painting of the air electrostatic automatic gun EAB500 virtually eliminated compensation for simple workpiece shapes.
2. By installing the operation panel in each booth, there was no need to go out of the booth every time the setting change was made. The work efficiency was improved while dust and seeding due to the entry and exit were drastically reduced.

Introduction : Powder coating has been introduced for general-purpose valves to prevent rust. The earthquake-resistant valves used solvent coating applied by hand spray, but due to the worsening of the working environment, heavy workload on workers, increased demand and a growing environmental awareness, an automated water-based coating system was introduced. Powder coating of general-purpose valves has reduced paint usage by 10 to 20%. In the automation of water-based coating, the number of line-workers was decreased from 7 to 1, which greatly reduced the manpower and workload.
