Dry vs. Wet Tumble

In the world of vibratory finishing there are two choices, wet or dry processing. 99% of vibratory finishing is run in a wet application but both applications have their pros and cons. Wet Tumbling Pros Wet applications have several benefits and few limitations. When running a wet application all types of media are eligible for use… ceramic, plastic, synthetic, porcelain, abrasive or non abrasive. The most apparent benefit is a cleaner, more polished part. Water combined with a vibratory compound cleans the part and keeps the media from building up impregnated soils, keeping the process clean and efficient. Media wear can slow when using a wet application, which saves the customer on cost during the application. Customers are able to clean, de‐burr and inhibit parts in one step as well. Wet Tumbling Cons Wet applications will produce an effluent you may need to treat. Whether you are using a closed system, pumping it out or sending it down the drain; you need to be aware of the method and costs involved in each. Drying parts is a normal secondary process that needs to be accounted for. Centrifugal Dryers and in‐line systems are common but require planning on your part. Dry tumbling Pros Dry applications are not common in vibratory finishing. Any media style is possible… however not recommended. It will usually be accomplished with a synthetic or non abrasive media to help control dust. There is no compound cost or waste effluent to worry about which can offset the high cost of the media.   Dry Tumbling Cons The media required for dry tumbling is expensive. The process requires specially engineered formulas that produce minimal dust and break down slowly. To maximize the life of your media, washing the parts before you run them is necessary. Heat can also be a concern with dry processes. The amount of friction in a machine can vary, however the time cycle, type of media and how aggressive you run the machine all play a role. Dry tumbling can be VERY LOUD so noise abatement covers could be required. Using the right process is key to a successful project. Contact us if you are having any issues with your current applications, looking to increase efficiency or have a new start up. We have engineered both applications to meet customers needs so you can rely on our skill and prior experience to help you succeed!
