CASE STUDY − WASHING, RINSING AND DRYING
A major automotive manufacturer was restarting its engine production plant to produce new engines. The manufacturer was in need of a cleaner for use in their new final connecting rod washer. This washer was:
- A used washer from one of the manufacturers other plants
- Reworked to meet this engine production plant′s specific need of washing HS170 powdered metal connecting rods with bronze brushings (require 30-60 days of rust protection in an indoor storage environment)
The automotive manufacturer′s central engineering team contacted Quaker immediately for a cleaner recommendation. Quaker proposed using QUAKERCLEAN ® 624 CP
- A dual purpose, mild alkaline liquid
- Simultaneously cleans and protects metal surfaces
Runoff data: During the runoff, sediment testing was run on dirty connecting rods to establish a baseline. The baseline averaged 6.66 mg/part.
Several connecting rods were then run through the washer using a 4% cleaning solution of QUAKERCLEAN ® 624 CP in both the wash and rinse stages. Eight of these connecting rods were randomly pulled and also sent for sediment testing. The manufacturer had a target specification for this test of 5 mg/part. The sediment testing results for these parts averaged .41 mg/part.
