One of our core product lines is blank washing machines for metal stamping plants. The function of the blank washer is to clean metal blanks of any contaminants and then coat the blanks in a controlled film of drawing oil.

This oil is a requirement for the drawing process, controlling the film thickness to provide an optimum amount of oil, improves quality and reduces both costs associated with oil wastage and costs associated with rework issues due to panel blemishes caused by too much or too little oil.

Clean oil is essential, especially when pressing skin type panels. Ensuring that the oil is free from dirt and dust prevents blemishes from occuring during the drawing process and prolongs die life. Independant tests have confirmed that the PES Wash units are global leaders in panel cleaning and oil film application.
