The Right Nozzle for the Right Part
FLAT PANELS 
2.5 to 4mm spray nozzles
  • Reduce the effect of powder ‘fingers’ in the pattern that can cause heavy and light areas
  • Produce a little more forward velocity that disperses the powder more evenly
Remember…which nozzle depends or number of automatic guns in the system. Larger nozzles are preferred because of lower powder velocity.


WIRE GOODS
2.5 to 4mm flat spray nozzles
  • Allow powder to attract to the closest part, then travel through the others for good wrap as most wire goods are hung back-to-back or even 6 inches deep
Remember…wide conical or 6mm flat spray. Use conical if guns can be placed close to part.


EXTRUSIONS
Typically 4 or 6mm flat spray nozzles with AFC set to 10 to 20 mµA
  • Allow good penetration into recess areas, give good uniformity on flatter surfaces
Remember…2.5mm flat spray nozzles usually have too much forward velocity to penetrate recessed corners of extrusions.


WHEELS
Occasionally 90-degree cross-cut or conical nozzles
  • Penetrate any deep recesses, as guns are triggered on/off in these areas then 4mm flat spray nozzle set-up evens out the coating
Remember….6mm or cross-cut; conical with AFC set to 15 mµA


CAVITIES
For porcelain enamel, conical nozzles On standard powder, 4mm and/or 6mm flat spray nozzles
  • Nozzle type depends on how parts are hung
Remember….6mm or cross-cut; 60 degree flat spray for flat areas and cavities
