The Seven Tank Pre-Treatment Process generally includes:

• Degreasing – Removes oil, grease, and dirt

• Water Rinse – I – First stage cleaning

• Derusting / Pickling – Eliminates rust and scale

• Water Rinse – II – Neutralization

• Phosphating – Improves paint bonding & corrosion resistance

• Water Rinse – III – Cleans excess phosphate

• Passivation – Provides final protective layer

Our Seven Tank Systems are available in MS, SS, and PP tanks, with manual, semi-automatic, or conveyorized plant options. These plants are widely used in automobile, fabrication, electrical, furniture, and heavy machinery industries.

With Great India Oven, you get turnkey installation, custom design, and reliable after-sales support, ensuring your metal finishing process is smooth, efficient, and cost-effective.
