Product Summary
The KAIWEI KW-520A is a two/three-component polyurethane gasket dispensing machine designed for automatic sealing of electrical enclosures, control panels, junction boxes, and more. Featuring a 10.2-inch touch screen, motion control card, and KAIWEI/Barmag metering pump, it delivers precise seal strip widths from 4 to 30 mm at speeds up to 12,000 mm/min. The machine supports PC or teach pendant operation and is equipped with a KW800 mixing head. It uses high-pressure water cleaning and offers manual/automatic raw material filling. The frame is a 3-axis linear robot arm with guide rails from KAIWEI or AIRTAC, Nidec servo motor, and Senad reducer. Powered by 220V/380V, 4/5.5 kW, it requires ≥6 bar air pressure. Available in carbon steel, stainless steel 304, or aluminum alloy.
