Powder in threaded holes
Start with tapered or pull plug options selected by thread, diameter and depth.
Process solution
Powder Coating Masking
Prevent powder from reaching features that must remain clean by matching the masking method to actual geometry and oven cycle.
Process problem to product path
Studs and pins need clean threads
Use silicone caps selected by outside diameter and coverage depth.
Grounding or contact area must stay bare
Review flange or washer plug geometry for hole-plus-face coverage.
Flat areas need a clean coating edge
Review high-temperature tape or die-cut masking by surface and bake cycle.
