No.441 / January,2025

Electrostatic coating of controller exterior panel

Introduction : Improving workability and productivity was a challenge.
Benefits : Color changes were done by inserting and removing the paint hose because there was only one paint route. By replacing it with a reciprocator featuring independent left and right control and a two-component coating system, it was possible to secure a separate paint route for each. It is expected that the complicated color change process will be significantly simplified and productivity will nearly double.

No.440 / December,2024

Powder coating of metal products

Introduction : Due to the increase in orders, improving productivity had become an issue.
Benefits :
1. By updating the equipment and adding more spray guns, the coating area has been expanded. Now it is possible to apply the correct film thickness uniformly to all workpieces.
2. Previously, two people were continuously performing correction work throughout the day, but the frequency of corrections has decreased due to the dual-electric effect, thereby improving productivity.
3. Combined with the paint recovery capacity of the new booth, it is expected that paint usage will be reduced by 10 to 15%.

No.439 / November,2024

Electrostatic coating of architectural hardware

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.

No.438 / October,2024

Coating of metal products using Electrostatic powder coating handgun

Introduction : A new factory was built to meet the demand for high-value-added powder coating finishes.
The deciding factor in introducing the powder coating handgun unit was that it improved coating efficiency, solved the issues of increasingly complex workpiece shapes, and reduced electrostatic repulsion.
Benefits : By reducing electrostatic repulsion and improving paint adhesion, paint usage was reduced by 10%.
High coating efficiency has reduced costs and improved productivity.

No.437 / September,2024

Electrostatic coating of metal baking paint panel “Mu-Wall”

Introduction : An automation machine was introduced to solve the problem of uneven coating during the intense heat of summer.
Benefits :
1. The layout of the equipment has been revised to achieve compatibility between automatic coating and hand spraying.
2. Automation has made it possible to achieve consistent quality with no uneven coating.
3. By using a reciprocating machine to paint following the shape of the workpiece, paint usage was reduced by 10%.

No.436 / August,2024

Electrostatic coating of steel furniture

Introduction : In order to solve the problems of inconsistent quality and labor shortages, an automated coating system was introduced to the manual solvent coating line.
Benefits :
1. Automation and the excellent coating efficiency of the gun have stabilized quality and eliminated coating defects.
2. The coating work, which previously required two to three people, was reduced to just one, achieving labor savings.
3. Improved productivity.

No.435 / July,2024

Robot painting of manhole for ship

Introduction : In order to solve such issues as the aging of coating workers, the shortage of man-hours, and the difficulty of securing young human resources, we constructed an automated system with coating robots and handling robots.
Benefits :
1.Automated coating system eliminates delays caused by waiting for coating.
2.Work time is shortened and productivity is improved.
3.The company established a production system capable of responding to future increases in orders.

No.434 / June,2024

Powder Coating of Frame for Electric Mobility

Introduction : Established Japan's first electric mobility OEM factory in Okinawa.
Benefits : The high coating efficiency and excellent finish of the electrostatic powder gun enable the company to achieve its goal of thoroughly reducing environmental impact.

No.433 / May,2024

Robotic coating of Hydraulic cylinder

Introduction : Built a new robotic coating line-in-house to solve issues with quality variations caused by hand spray and the lead time in the outsourced coating process.
Benefits :
1. Coating qualities were stabilized and the rate of defects was greatly reduced by combining with an EAB400R that is angled at the gun tip and allows coating with less robotic motion.
2. By the automation, the burden on workers could be drastically reduced, and the shortening of the lead time was realized.

No.432 / April,2024

Robot coating for architectural Fasteners

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.
