This particular manufacturing system is made by bristles of filaments supported either by a plastic (PVC, Moplen, nylon, etc.), or wooden, aluminium or brass made support.
Each bristle comes to be firmly stapled to the support, fixed to holes previously created.
This particular assembly grants this type of brush flexibility in order to adapt different parameters and to satisfy various requirements, thanks also to their moderate weight.
These kind of brushes are suitable especially in presence of water, solvents and acids.
