This is a common technique for coating metal—not just for looks, but for corrosion resistance too. It's called powder coating dipping. First, the metal is heated above the melting point of the powder. Then it's dipped into a fluidized bed—basically a container of powder made to behave like a liquid using pressurized air. When the hot metal touches the powder, the polymer melts instantly and sticks evenly. As it cools, it forms a tough, smooth, and durable finish.#metal #industrial #coating #powder #technique #tech #technology #facts #education
