Dipping degreasing baths generally consist of alkaline degreasing
chemicals. Along with high alkalinity and temperature, degreasing
process is performed on metal. It is suitable to use before iron
phosphate, zinc phosphate and manganese phosphate coating baths.
Degreasing additives can also be used to increase the effectiveness of
In spray degreasing baths, there is an additional pressure difference
compared to dipping baths. Thanks to the pressure, the cleaning effect
is maximized. Bath temperature is lower than dipping systems and
process time is shorter. Appropriate degreasing chemical should be
selected according to the type of metal and the amount of oil/grease
on it. It can be used in iron, steel, copper, zamak, brass, aluminum
and galvanized parts.
Ultrasonic degreasing baths remove oil on metal parts with the help of
sound vibration, chemical effect and temperature. In general, it can
work with neutral degreasing chemicals as well as working in medium
alkaline environment. The bath temperature is not high and the
processing times may be longer depending on the amount of grease layer
on the metal.
