The plant environment that encircles the powder application process may have many contaminants that can be detrimental to a quality finish on a powder coated part. These can include airborne oils from press and machining operations, dust from grinding and packaging operations, and many other forms of particulate. Any or all of these contaminants can cause problems with quality finish and system efficiency in your powder operation.
High heat and humidity from ambient temperatures and the ovens and washer can be detrimental to the powder application and reclaim systems, creating inefficiencies and excessive maintenance. High humidity and temperature can cause the powder to stick together in clumps and resist fluidization and flow. Agglomerations in the powder may cause protrusions in the powder film.
