aseanzip_boss · 3d agoWe are getting dull deposits in bright acid tin barrel plating, mainly on the top layer of parts and near the barrel door.
Our bath is within supplier ranges, but the dull areas look like poor contact or solution starvation. What should we check first?
- Barrel loading and tumbling
- Contact cleanliness
- Bath temperature and agitation
- Additive dosing and analysis frequency
A troubleshooting order would help the team respond consistently.
