The most important step in any metal finishing process line is cleaning. Without an effectively clean surface, no coating or plated deposit will consistently adhere to the substrate and rejects will occur. Often there is no knowledge of what is on the surface of the parts, so an effective cleaner will have to be capable or removing many types of oils and soils. Here are some things we need to know to help recommend the best cleaner for your application:
- Type of metal to be cleaned – aluminum, brass, copper, steel, zinc die cast, etc.
- Type of parts – machined, casting, stampings, fasteners, etc.
- If possible, what type of oil is on the surface – soy based, paraffin based, petroleum based, etc.
- Type of cleaning process – immersion or spray
- Processing style – rack, barrel, rotary drum, etc.
- Operating capabilities – cleaning time, maximum temperature available, etc.
Why are there so many different types of metal cleaners to choose from? At the root of this question are the many variables a metal finisher has to consider when processing a customer’s parts. The short answer is, there are many different cleaners because no one cleaner can be one hundred percent effective for every application.
Changes in metal cleaning technologies are driven by the changes in metal cutting fluids, lubricants and coolants. As these chemistries change, improvements need to be made in the surfactants and cleaning agents that help remove them from the metal’s surface.
