2. Spray cut and automatic guns significantly reduced unnecessary spraying. ３．The need for pre-touch-up was virtually eliminated, and uneven coating was nearly resolved.

No.456 / June,2026

Powder Coating of Switchboards and Distribution Board Enclosures

Introduction:While the company has been promoting labor-saving measures in its manufacturing processes, coating operations relied on manual spraying, making labor shortages and low productivity key issues. Meanwhile, to reduce workload caused by Okinawa’s high temperature and humidity and heat from the drying oven, the company introduced an automated coating system.

Benefits
1. Powder automatic guns reduced coating time to approximately 1/3.
2. Stable coating quality virtually eliminated coating defects and recoating, improving productivity.

No.455 / May,2026

Powder coating of crane parts

Introduction:To address insufficient coating on recessed and inner surfaces, increased touch-up coating, and higher paint usage, the company introduced a new system that automatically detects part shape and maintains the optimal coating distance.

Benefits
1. A 3D reciprocator enabled the coating gun to follow each part shape, achieving uniform coating film formation and significantly reducing touch-up coating.
2. The new system improved productivity by reducing line stoppages and is expected to reduce paint usage by approximately 30%.

No.454 / April,2026

Electrostatic coating of curtain rail components

Introduction：Facing challenges with aging equipment—such as inconsistent coating quality, low transfer efficiency, increased paint consumption due to touch-up coating, and a deteriorating working environment—the company implemented a new coating system.

Benefits
1. A high-transfer-efficiency automatic coating gun reduced paint consumption by 30% and improved the defect rate from 15% to nearly zero.
2. Touch-up coating was eliminated, reducing operator workload and improving the working environment by reducing paint mist.

No.453 / March,2026

Powder coating for ventilation hood system components　　　　　　　　　　　　　　　　⁂　　　　　　　　　　　　　　　　⁂

Introduction:To address low efficiency in small-lot production lines, the company established a dedicated powder coating line to improve overall productivity.

Benefits
1. Productivity increased by 7% and the defect rate decreased by 3.5%.
2. The introduction of a proprietary powder gun reduced paint consumption by 20% and significantly reduced correction frequency.

No.452 / February,2026

Automated Robotic Coating for Hydraulic Cylinders　　　　　　　　　　　　　　　　⁂　　　　　　　　　　　　　　　　⁂

Introduction：To resolve quality variation, booth contamination, complex color changes, and low productivity caused by hand spray coating, the company upgraded to an automated coating system.

Benefits
1. By using an automatic spray gun with an angled compact head and optimized coating robot paths, teaching was simplified，which reduced overspray, lowered paint consumption, and improved productivity.
2. The introduction of a color change valve enabled one-touch color switching, eliminating complicated color change operations.

No.451 / January,2026

Powder Coating System for LP Gas Cylinders　　　　　　　　　　　　　　　　⁂

Introduction: To address rising paint usage, reduced recovery efficiency, and worsening work conditions caused by aging coating equipment, the company introduced a new powder coating system, featuring automatic coating guns.

Benefits
1. The new system achieved higher coating efficiency and excellent coverage, improving coating productivity by 25%.
2. With the improvement of the work environment by reducing overspray, the enhanced parts supply system and after-sales service have received high praise.

No.450 / December,2025

Electrostatic Heat-Resistant Coating for Microwave Oven Grill Frames　　　　　　　　　　　　　　　　⁂

Introduction:To address aging equipment and improve coating quality and labor efficiency, the company renewed automatic spray guns on two coating lines.
Benefits
1. Paint consumption and touch-up work were significantly reduced, increasing correction-free production and improving process efficiency.
2. Uniform, high-quality finishes were consistently achieved, contributing to labor savings.
3. The upgrade of the automatic spray guns delivered measurable gains in quality, productivity, and cost efficiency with minimal investment.

No.449 / October,2025

Powder Coating for Air Conditioner Outdoor Unit Panels

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.

No.448 / September,2025

Powder Coating of Metal Products　　　　　　　　　　　　　　　　⁂　　　　　　　　　　　　　　　　　　　　　　　⁂　　　　　　　　　　　　　　　　　　　　　⁂　　　　　　　　　　　　　　　　　　　　⁂　　　　　　　　　　　　　　　　　　　　　　　　⁂　　　　　　　　　　　　　　　　　　　　　　⁂　　　　　　　　　　　　　　　　　　　　　　　　　　⁂

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%.
