  • Specialist in painting
Client Name:
Tanabe coating Limited Partnership
Used paint:
Solvent paint
Product used:

Automatic Electrostatic Air Spray Gun: Sun gun Ⅲ EAB500(EAB500)

Introduction : Due to the aging of the coating system and the instability of reciprocating control caused by the weight of the bell electrostatic gun, a new system was installed to stabilize coating quality.
Benefits :
1. Touch up work that was always necessary for the bell coating became no need.
2. Defects caused by dirt and dust are greatly reduced by the fact that workers are no longer in the booth.
3. Improvement of the defect rate from 20% to 10% or less.
4. The use of paint has been reduced by 10% through the use of an automatic gun that achieves both high coating efficiency and excellent atomization.
5. Productivity is also improved.

No.424 / July,2023

Electrostatic coating for Bed frame

  • Specialist in painting

Introduction : A new system was introduced with the founding in May 2023.
Benefits :
1. Liquid automatic coating gun and liquid hand gun enabled high coating efficiency and atomization.
2. The latest electrostatic powder coating hand gun provides very little powder fall-off and high-quality coating even in thick coatings. Easily coat onto corners and weld angles.
3. More than 10% reduction in the amount of paint used than the previous model can be expected.

Powder coating of Aluminium Building Materials

  • Specialist in painting
Client Name:
Marushin Co.,Ltd. Matsubushi Plant
Used paint:
Powder paint

Introduction : The company, which specializes in coating, renewed its reciprocating machines to cope with the trend toward larger products.
