Product Summary
The KW-520A is a programmable polyurethane gasket dispensing machine built on a 3-axis linear robot arm. Its 2250 x 1250 x 200 mm effective stroke provides a practical working area for large flat and gently contoured parts such as electrical cabinet doors, lighting panels, filters and automotive covers.
A 10.2-inch PC touch screen, integrated operation box, motion-control card or PLC architecture and Nidec servo motor support programmable production control. The KW800 mixing head produces 4-30 mm seal strips at programmed travel speeds of up to 12,000 mm/min, and a 1-10:1 mixing ratio with KAIWEI or Barmag metering pumps lets one platform run different polyurethane formulations.

Materials and Structure
The frame is available in carbon steel, stainless steel 304 or aluminum alloy. The 3-axis linear robot arm runs on a square-tube welded workbench measuring 2000 x 1000 x 800 mm, driven by a Nidec servo motor and Senad reducer. Two 40 L air-pressure tanks feed the KW800 head, with agitation on tank A and an oil-water separator on the air line.
Equipment compliance: CE certificate MD-TCF-240307-55472 issued by GTS against the 2006/42/EC Machinery Directive (scope: automatic gluing equipment, valid 2024-04-02 to 2029-04-01); ISO 9001:2015 certificate from NSY Certification, valid to 2027-05-22. PU material documents supplied with the machine include UL94 (THSH25033168768EN), RoHS (UNIB21090613HC-01) and a non-hazardous certificate (NO.202600234403353).
Applications
The KW-520A dispenses polyurethane gaskets on electrical control panels, distribution boards, electrical enclosures, explosion-proof boxes and shells, home appliances, cable connectors, automotive fittings and battery covers, air filters, lock shells, purification room and refrigerator doors, transformer covers, street and stadium lighting, LED luminaires, waterproof cabinets and boxes, transparent boxes, ABS junction boxes and lamp covers. Typical production runs use dust-proof and explosion-proof sealing with IP66 requirements, in ambient temperatures of -20 to 40 degrees C, on 24/7 automatic gluing lines.

FAQ
What working area does the KW-520A cover?
The 3-axis linear robot arm travels a 2250 x 1250 x 200 mm effective stroke, which suits cabinet doors, lighting panels, filters and automotive covers within that envelope.
Can it dispense both two-component and three-component PU?
Yes. Component selection is configurable for two-component or three-component polyurethane, with a mixing ratio range of 1-10:1.
What seal strip widths can the KW800 head produce?
4-30 mm, covering narrow dust-seal beads as well as wider gaskets for explosion-proof and IP66 enclosures.
How is the mixing head cleaned?
By high-pressure water from a tap-water supply. The water tank uses a front level sensor and outlet filtration.
What site services are required?
220V or 380V power at 4 kW or 5.5 kW, compressed air of at least 6 bar through an oil-water separator, and tap water.
Can it run continuously in an automatic line?
Yes. Dual 40 L air-pressure tanks with manual or automatic filling and air charging, plus an optional filling station, support 24/7 automatic gluing line operation.
Which frame materials are available?
Carbon steel, stainless steel 304 or aluminum alloy, on a square-tube welded workbench of 2000 x 1000 x 800 mm.
