5. Sound and preparation for colouring.
At this stage, Dzen Drum is already making sounds, but the notes are false. Music requires precision, so our masters manually tune the instruments until the tuner shows absolutely pure notes tuned to a frequency of 432 Hz and 528 Hz. Then artistic engraving is applied, which adds charm and individuality to each instrument.
6. Hardening and colouring.
After the instrument has been tuned, we apply an anti-corrosion coating and send it to the workshop for colouring. We prepare the instrument for colouring: remove any remaining dust and degrease it to increase paint adhesion and additionally protect the product from corrosion. In the spraying chamber we apply powder varnish and send it to bake in the polymerization oven, under certain temperature and time so that a top coating forms.
7. Quality control and packaging.
Final check of the instrument according to the checklist: sound, quality of colouring, general appearance, etc. The final stage is when Dzen Drum is ready to ship.
