Slot Coating Gun – Precise Strip Hot‑Melt Scraping for Packaging Lines

slot coating gun is engineered for high‑speed, uniform strip hot‑melt scraping in automated packaging workflows. Maximum scraping width reaches 25 mm, and it runs steadily at more than 3500 cycles per minute.Built with wear‑resistant alloy scraping components, the unit maintains long‑term stable scraping quality even under heavy‑duty continuous shifts. Operators carry out real‑time parameter tuning to adapt glue thickness for different carton substrates.

The 24 VDC solenoid valve offers fast response, while Ni120 temperature sensor keeps accurate temperature control up to 200 °C, suitable for adhesive viscosity up to 10 000 mPa.s.Thanks to its universal mounting design, HRP‑02 can be quickly fitted on folder gluers, taping platforms and special‑box processing machines. No complicated modification is required for retrofitting old production lines.

It avoids uneven glue‑strip defects common from manual or roller‑based coating.Typical applications include gift‑box edge bonding, carton flap sealing and composite material lamination. Printing factories benefit from neat, consistent hot‑melt strips, fewer glue‑related defects and simplified daily maintenance. Combined with Keqi hot‑melt heating pumps, it forms a reliable strip‑coating system for mixed‑batch packaging orders.
