Coil-fed washer reduces stamping defects
- August 9, 2020
These washers strip away any particles larger than 20 microns (.000788-in.) from the workpiece to improve surface quality.
The hot water washers’ reverse osmosis system ensure constant quality of incoming water for the washing process. They handle coil materials up to 84-in. in width and achieve a typical line speed of 300 fpm. The wash systems offer the right heat, pressure and flow to clean material.
The systems include entry and exist mist containment, which prevents moisture and steam from escaping into the factory. A spray chamber contains the spray headers and nozzles, directing water onto the material. An air knife system uses low pressure, high volume air to blow the water off the strip, resulting in dry material exiting the washer.
The system entry and exit have opposing rolls to support and drive the material through the machine. All peripheral washing equipment for process water storage, heating, pumping, filtering, oil/water separation and moisture containment are included.
These hot water systems are typically paired with an AFCO supplied electrostatic re-oiling system with a metering pump to provide uniform film thickness at line speeds.
