01

Pre-Treatment Equipment

  • Immersion Type Pretreatment Equipment

    • Online immersion systems

    • Offline immersion systems

    • Fully automated offline immersion systems

  • Spray Type Pretreatment Equipment

  • Sandblasting/Shot Peening Pre-Treatment Equipment


Pre-treatment is an essential step in the coating process, ensuring the workpiece surface achieves the required cleanliness and adhesion for superior coating quality, enhanced durability, and improved corrosion resistance.
The ultimate goal of pretreatment is to remove surface contaminants such as grease, dirt, moisture, oxides, and rust, laying the foundation for the adhesion and corrosion resistance of subsequent coatings. Even with high-performance coatings, improperly treated surfaces are prone to problems such as blistering, peeling, and rusting. Therefore, pretreatment plays a decisive role in the coating process.
Depending on customer needs, the main steps include:

Degreasing

Removes oil and dust using hot water and detergents.

▨ Acid Washing

Eliminates oxides and rust, activating the metal surface.

▨ Sandblasting/Shot Peening/Surface Adjustment

Enhances surface roughness, fatigue resistance, and hardness.

▨ Conversion Coating

Forms a protective chemical layer to improve adhesion and corrosion resistance.

▨ Rinsing and Pure Water Rinsing

Removes chemical residues in every main steps.

▨ Rust Prevention

Adds a protective layer to avoid oxidation after rinsing.

▨ Water Removal & Drying
Ensures surfaces are completely dry before coating.

04

Electrodeposition (ED) Coating Equipment

  • Pure Water Equipment

  • Electrostatic Power Supplies

  • ED Ultra Filtration


ED coating uses an electric field to deposit paint particles onto submerged workpieces. This technology is commonly used in the preparation of protective coatings for metal surfaces to improve rust resistance and form a strong film through electrophoresis to enhance the product’s corrosion resistance. It has the advantages of high efficiency, good uniformity, and environmental friendliness.

 

05

Steel Pipe Coating Equipment

  • Aqua Coating

  • UV Coating

  • Powder Coating

  •  Zinc Melt Blown


Pipes face various environmental challenges during manufacturing and use, such as corrosion, wear, and oxidation. Therefore, different coating technologies are required to improve their performance and extend their service life.

06

Steel Coil Coating Equipment

  • Roll-to-Roll Conveyor System
