Automotive parts manufacturer case study

The heat-treating operation at this major automotive bearing manufacturer in Georgia involves quenching parts with oil followed by an aqueous cleaning proc-ess. Two cleaning tanks were dumped and re-charged weekly when they became too contaminated to clean parts effectively.

The parts were susceptible to staining when the cleaning solution became overly contaminated and the furnace would generate excessive smoke in the plant. The customer established a goal to eliminate part staining and smoke, while reducing overall operating costs.

Separation Dynamics provided an Extran Ultrafiltration System to continuously remove emulsified oil from the washwater in both tanks and improve the cleaning effectiveness. The washing solution is now recycled instead of weekly dumping—saving valuable cleaning chemicals, significantly reducing waste and eliminating excess smoke from the furnace.
