E-Coating Masking
E-coat masking must be selected against the full process sequence, including liquid exposure, geometry and post-process removal.
Process problem to product path
Thread leakage
Check plug geometry, fit and removal after immersion and bake.
Different programs use different parts
Maintain approved size records linked to the customer's drawing or reference.
Unusual geometry
Use a drawing-based custom masking review after standard options are checked.

Frequently asked questions
Why is E-coat masking different from dry coating masking?
Immersion and exposure can change the fit and leakage risk, so the complete process sequence is required for selection.
Should I test parts after the entire E-coat cycle?
Yes. Fit, sealing and removal should be tested under the actual sequence before approving a repeat order.
