FEATURE

Less paint needed

 As a result of the high electrification efficiency of the paint and a maximum of 10% improvement in the coating

 efficiency compared to conventional products, the effect of reducing the amount of paint used can be expected,

 and the amount of correction is further reduced.

 In addition, we can expect a reduction in the amount of industrial waste in the case of only blowing away.

Improved finish

 While maintaining high charging efficiency, it suppresses the generation of free ions and realizes a smooth

 finished surface with less reverse ionization (electrostatic repulsion).

Improved re-coating

 The dual electric field reduces reverse ionization (electrostatic repulsion), resulting in a smooth coating even when

 recoating.

Reduced coating time

 With a maximum discharge rate of approximately 350g/min, more paint can be deposited in a short time,

 improving work efficiency.

Expansion of pattern width

 From plane to depth, you can select the nozzle that matches the object to be coated and the process,

 and the pattern can be changed.

Shorter cleaning time

 The seamless construction of the gun body reduces cleaning time.

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%.
