Plastic dip coating is a technique where metal parts are coated with a plastic vinyl material. It is used to protect, accessorize and make the metal parts more durable with respect to scratches and abrasions. The process is used on medical instruments, toys, electrical equipment and many more items.
The first part of plastic dip coating involves cleaning the instrument to be coated. Next, the instrument is heated and dipped into a liquid plastic polymer and baked. The temperature depends on the characteristics of the polymer being used. Afterward, the coated instrument is removed from the heating element and cooled with water.
