No.445 / June,2025

Powder Coating of High-Pressure Gas Cylinders　　　　　　　⁂

Introduction : In response to environmental concerns and the need to improve work efficiency, the company introduced an eco-friendly powder coating system and revamped its coating line.
Benefits :
1. Improved work efficiency by eliminating the need for color changes through the use of dedicated booths for each paint color.
2. Enhanced the working environment by reducing paint overspray outside the booths.
3. Increased productivity with a uniquely designed booth and high-efficiency coating gun.

No.444 / April,2025

Robot Coating of Breaker Boxes for Semiconductor Equipment

Introduction: The company has expanded its factory and introduced automatic systems in anticipation of rising demand in the booming semiconductor industry. The robot coating system was installed to replace the traditional manual spray coating process.
Benefits:
1. By improving the efficiency of coating guns, it has ensured consistent product quality and greatly improved productivity.
2. Addressed labor shortages and improved employee well-being through automation.

No.443 / March,2025

Powder coating of metal products

Introduction：Due to concerns about a future labor shortage, the manual spray booth was renovated, and an automatic electrostatic coating system was installed to reduce manpower.
Benefits：
1. Correction work that previously required two workers can now be handled by one.
2. Established a system that allows us to maintain productivity even with reduced staffing, while still meeting customers' demands.

No.442 / February,2025

Electrostatic coating of building materials

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.

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.
