Q.

We maintain the free acid at 0.7-1.1 points and total acid at 20-24 points, and the total fluoride at 1,500 ppm. Bath temperature is 40°C to 45°C. Any suggestions?
Parts Cleaning Clinic: Pretreatment Equipment Suppliers
Q. I am researching manufacturers of aqueous part washers and phosphate pretreatment systems for powder coating, looking for companies that build conveyor systems, washers and treatment systems; not parts washers. The parts to be cleaned are various sizes of steel, stainless and aluminum fabrications from stampings, cut to length steel tubing, and sheet metal fabrications up to 6 feet long and 3 feet wide. What are my options?
