Mask Threaded Holes Before Powder Coating
Threaded-hole masking requires the correct hole fit, insertion depth and removal method before the coating line starts.
Capture the thread condition
Provide the thread size, depth and whether the hole is blind or through.
Select a sample range
Test suitable tapered or pull plug options around the measured geometry rather than assuming a generic plug will seal.
Check after bake
Inspect for powder entry, removal effort and any plug wear after the actual oven cycle.
