Application Methods / Fluid Bed Coating

Fluid Bed Coating

The process involves suspending the powdered material in an air stream, creating a fluidised bed of powder that allows for a uniform coating of the substrate.

This process is a versatile and efficient method that can be divided into five main steps:

1. Cleaning the substrate of the object to be coated

2. Storage of plastic powder in a container with special equipment for blowing air in a modular and uniform manner

3. Preheating of the object, typically 180 to 220 degrees Celsius

4. Immersion in the fluid bed where the powder particles adhere to the surface creating a uniform coating, this usually takes a few seconds as shown in the video opposite with a laboratory sample

5. Curing and hardening of the coating through subsequent heating of the finished object, the time and temperature may vary depending on the shape and size of the object

The resulting polyethylene coating guarantees durability, chemical resistance and abrasion resistance.

Advantages of fluidised bed coating
  • The resulting coating guarantees durability and good mechanical properties

  • Has excellent chemical resistance and abrasion resistance

  • Provides even coverage on objects

  • Reduced waste production

  • Large numbers of objects can be mass printed

  • Applications are constantly increasing
