Vacuum painting

The vacuum coating is the flooding related method for continuous coating of profiles, which is mainly in the coating of wood used.

The process is characterized by an application efficiency of almost 100%. In principle, a profile runs through a vacuum chamber in which the material, which is necessarily very thin for this, is injected and atomized. The prerequisite is a continuous profile that can run into the vacuum chamber through an approximately precisely fitting opening on one side and run out on the other. Since the paint material runs through a circuit in the device and no overspray escapes from the device due to the vacuum , there are virtually no losses during operation and only the paint material applied leaves the system.

A vacuum painting system essentially consists of the following components:

Application chamber
Vacuum pump
Paint pump (eg: double diaphragm pump )
Air filter

Conventional belt speeds are between 10 and 30 m / min.
