PU Gasket Dispensing Machine KW-520B - Advanced Three-Component Model
Product Summary
Built on the KW-520B platform, this advanced configuration utilizes a stainless steel 304 frame, three-component metering system with precision Barmag pumps, and automatic raw material filling. It is designed for demanding environments such as explosion-proof enclosures and automotive paint shops where corrosion resistance and high automation are critical. The machine supports IP66 waterproof and dust-proof gasket applications and operates continuously in automatic production lines.
Key Selling Points
- Three-Component Polyurethane System: Allows precise mixing of polyurethane with additives for tailored gasket properties. Adjustable ratio 1:1 to 10:1 ensures optimal sealing for explosion-proof and high-temp environments.
- Stainless Steel 304 Frame: Corrosion-resistant structure suitable for cleanrooms and harsh industrial settings. Increases durability and longevity compared to carbon steel.
- Barmag Metering Pump: High-precision gear pump from Barmag ensures consistent shot size and ratio accuracy, crucial for automotive and enclosure sealing.
- Automatic Filling and Air Charging: Reduces manual intervention, supports 24/7 operation with automatic raw material replenishment and air pressure management. Optional water temperature control available.
- Comprehensive Certifications: CE, ATEX (ECM 25 ATEX-B D001), UL94, and RoHS compliant. ATEX certification covers explosion-proof enclosure sealing.

FAQ
What is the advantage of three-component over two-component?
Three-component allows adding a third additive (e.g., flame retardant, color, or adhesion promoter) for customized gasket properties. Ideal for special applications like explosion-proof seals.
Is the stainless steel frame food-grade?
Stainless steel 304 is general-purpose corrosion-resistant. For food contact, additional coatings may be needed. Consult KAIWEI for specific requirements.
Does it support IP66 gasket?
Yes, the seal strip produced can achieve IP66 waterproof and dust-proof rating when applied to proper enclosures. A US automotive customer uses this machine for IP66 paint shop cabinets.
What certifications does the machine have?
CE, ATEX (ECM 25 ATEX-B D001 for explosion-proof enclosures), UL94 for foam, RoHS for materials, and ISO 9001:2015. Also Non-Hazardous Certificate for transport.
Can it run 24/7?
Yes, designed for continuous operation in automatic production lines. Automatic filling and air charging minimize downtime.
What is the raw material tank capacity?
Standard tanks A and B are 40L each. For three-component system, a third tank can be added as option. Filling is automatic with manual backup.
Is there a case study available?
Yes, a US automotive OEM used 20 units for paint shop sealing over 2 years, achieving stable operation and IP66 protection. High precision dispensing and custom gasket shapes were highlighted.
