Global Finishing Solutions – Multi-Stage, Pre-Treatment Systems, & Parts Washers

GFS Washers are used in the electro coat process and pre-treatment of Class A finished surfaces. Parts requiring high corrosion protection such as: exterior automobile parts, aluminum wheels, appliances and office furniture may require multiple washer stages as determined by your specific process. Washers are used to clean and prepare substrates prior to powder and liquid coating, electro coating and auto phoretic coating, GFS Washers are used before or after machining or forming of component parts. GFS also designs and builds heated Blow-Off Units and Dry-Off Ovens to completely dry parts after washing operations.

The number of stages and the design of a Washer System depend upon the customers’ finish specifications and the complexity of the parts to be washed. A GFS Washer can be designed and customized as a spray, immersion, or combination of both types. Most basic Washer Systems include a chemical cleaning stage, followed by water rinse, and seal rinse stages. Per specification requirements, the washer may include the addition of phosphate stages, additional rinse stages, and RO or surfactant final rinse stages.
