Industrial crankcase parts washer

The customer needed an industrial parts washer for the cleaning and drying, inside and out, of aluminium oil crankcases with an output of 30 parts/hour. It was necessary to eliminate contamination from cutting oil and metal shavings left over from the machining processes. After washing the parts, residual surface contamination must be less than 25 mg/1,000 cm², with a maximum particle size of 1,000 microns.

Due to subsequent leakage control, the components may not exceed room temperature by more than 5ºC when they exit the washer.

Parts are loaded and unloaded manually.
