Paint, Synthetics and Enamels Stripping with Oxidizing Salt Melts.
Posted on Jul 31, 2024To ensure the best transfer efficiency while painting, tooling/fixtures/jigs are used to orientate components correctly, they also help to optimize output. So, a good jig design & its maintenance are essential to the profitability of any plant.
The problem with jigs is that they become coated during the paint process. Every time a part is painted an additional layer of paint is added to the jig. This continuous buildup of paint will cause rejects if not removed. For example, it may electrically insulate parts preventing E-cote or KTL from depositing. They may introduce contamination which is seen as roughness or flaking on the coated part. Also, they may start to mask the work piece creating thin or missing areas of paint.
Now you have an additional problem of remove paint & reworking your part. Introducing cost, time & risk into your business.
Jigs are often complex, expensive & in constant production. So, cleaning is difficult for a few reasons:
- Finding time to remove them from production for cleaning is limited.
- The cost of buying additional jigs is often not commercially viable.
- The cleaning process must remove paint buildup without damaging the jig.
Oxidizing salt melts deliver quick (approx. 15 minutes) and thorough removal of organic materials and enamels. he fluidity of the salt melts guarantees immediate contact with the substances to be removed, even on intricately-shaped work pieces.
The oxidation process is accelerated or controlled by activating additives which, among other things, hinder chemical attack of the base material.
The field of application for salt bath cleaning is very broad and ranges from cleaning of metal surfaces to the removal of synthetics from manufacturing.
