PURIMA, the parts cleaning specialist from Porta Westfalica, took on the task of cleaning, rinsing and drying complex workpieces. For customers who, among other things, maintain ship components and manufacture large engines for the shipping industry, PURIMA has developed an automated cleaning system that cleans large-dimensioned, 110-ton, cylinder crankcases of ship engines fully automatically and efficiently. They are manufactured mechanically before you clean them and are contaminated by chips, oils, cooling lubricants or casting dust. Since the large workpieces are geometrically complex, we were faced with the challenge of cleaning not only the surfaces, but also all recesses and bores with the utmost precision.
