Cataphoresis Line

Automotive Cataphoresis Line for High-Performance Corrosion-Resistant Component Coating

The automotive cataphorese line utilizes high-tech cathodic e-coating techniques to deposit an even thickness of film on each of the series’ automobile chassis, brackets and structural components, providing OE manufacturers and first-tier companies with the peace of mind that their production rates will remain consistent with those of the cataphorese line because of superior corrosion resistance.

Advantages of Cataphoresis Line

Uniform Coverage on Complex Parts

Advance electric field control results in complete coating penetration to edges, weld seams and recess areas.

High Resistance to Corrosion

Cathodic epoxy and hybrid coatings provide long-term salt spray resistance with superior adhesion.

Automated and Energy Efficient

PLC and SCADA monitored automation, ultri-filtration recovery along with optimally designed curing systems result in reduced waste and operation costs.

FAQ

What is the difference between cataphoresis and electrophoresis?

Cataphoresis generally is to refer to cathodic e-coating that has significantly better resistance to corrosion. Both processes are immersion or wet coating in an electrically charged field.

Can the line accommodate multiple size parts in the same production run?

Yes, multiple size parts can be finished in the same run provided the rack and fixture designs are accurate.

What type of pretreatment is required prior to electrophoretic coating?

Typically when finishing steel a zinc or iron phosphate conversion will need to be applied. For aluminum an alternative to conventional chromate or phosphate treatments, chromium-free methods will be used.

Is the system designed with consideration of environmental impact?

Yes, all three processing steps utilize water-based coatings and include closed-loop rinse systems with a unique ultra-filtration recovery system to minimize hazardous chemical waste and volatile organic compounds.
