Grunig G-Coat 406 Screen Coating Machine

The G-COAT 406 is a newly developed automatic coating machine that features Grünig’s “Plug & Coat” technology—simply unpack, setup, and start coating. It is an extremely compact bench-top model and boasts a durable, low maintenance construction.

Coating is possible from one side, or both sides simultaneously using the included G-COAT 401 coating trough. All coating parameters can be quickly and easily programmed through the control panel. The coating process is extremely smooth thanks to special sliding guides and a toothed belt drive unit.
