Dip Spin Coating Line- highly efficient machine
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 oil, wax, rust inhibitors, 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
- Loading
- Parts are loaded into perforated baskets or fixtures (often via robotic or conveyor systems).
- Pre-Dip (Optional)
- Cleaning, degreasing, or pre-rinse stages may precede coating.
- 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.
- 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.
- Drying / Curing (Optional)
- Some lines include hot air blowers or infrared dryers to accelerate drying of water-based or solvent-based coatings.
- Unloading
- Coated parts are unloaded for packaging or further assembly.
