Zero‑Cavity Hot‑Melt Gun – Anti‑Clog Precision Dot‑Line Spraying

Keqi FH02‑Hf zero‑cavity hot‑melt gun adopts zero‑cavity nozzle structure with built‑in self‑cleaning function, greatly reducing nozzle blockage frequency and extending continuous maintenance intervals. It targets high‑speed fine dot and thin‑line hot‑melt spraying for premium packaging.Maximum operating speed exceeds 3500 cycles per minute; max scraping width 35 mm; acceptable adhesive viscosity up to 10 000 CPS. The temperature upper‑limit is 200 °C with Ni120 sensor for precise thermal control.

Operators adjust dot size and glue output in real‑time, shortening product change‑over setup time.Its compact assembly supports easy mounting on folder gluers and taping platforms. The self‑cleaning nozzle minimizes carbonized‑glue buildup, lowering unplanned downtime caused by nozzle jams. 24 VDC high‑response solenoid guarantees sharp glue opening‑closing action with minimal stringing.This zero‑cavity gun serves luxury wine boxes, cosmetic rigid boxes and high‑grade folding cartons.

Packaging manufacturers cut nozzle‑related failures and achieve stable fine‑pattern hot‑melt results. It works cooperatively with Keqi hot‑melt pump systems to deliver low‑maintenance high‑precision gluing for high‑value‑added packaging orders.
