Dip Spin Coating Line

A Dip Spin Line (also known as a Dip-Spin Coating Line or Dip and Spin Coating System) is an automated industrial surface treatment system primarily used for applying protective coatings—such as Dacromet, Magni , Geomet and DELTA( Dorken) or thin polymer films—to small to medium-sized metal parts in high-volume production.
It combines two processes: dipping (immersion) and spinning (centrifugal drainage), making it highly efficient for uniform, thin, and controlled coating application with minimal waste.

🔧 How It Works – Process Overview
1.    Loading
        Parts are loaded into perforated baskets or fixtures (often via robotic or conveyor systems).
2.    Pre-Dip (Optional)
        Cleaning, degreasing, or pre-rinse stages may precede coating.
3.    Dip Stage
        The basket is lowered into a tank containing the coating fluid (e.g., anti-rust oil, corrosion inhibitor).
        Parts are fully immersed for a set time to ensure complete coverage.
4.    Spin Stage (Centrifugation)
        The basket is rapidly rotated at high speed (e.g., 300–1500 RPM).
        Centrifugal force removes excess liquid, leaving a thin, even film on the part surfaces.
        Excess fluid is recovered and returned to the dip tank.
5.    Drying / Curing (Optional)
        Some lines include hot air blowers or infrared dryers to accelerate drying of water-based or solvent-based coatings.
6.    Unloading
        Coated parts are unloaded for packaging or further assembly.
