Zero‑Cavity Hot Melt Gun

The zero‑cavity hot melt gun features innovative zero‑dead‑volume internal flow path to eliminate stagnant glue storage space inside the gun body. This design fundamentally reduces adhesive carbonization and frequent nozzle clogging that trouble traditional hot‑melt applicators. Self‑cleaning nozzle structure extends maintenance intervals. It reaches over 3500 cycles per minute, handles viscosity up to 10 000 mPa.s with max temperature 200 °C.

Outstanding advantages: real‑time glue‑dot size adjustment without disassembly, greatly shortening production debugging and mold‑change time. Clean cut‑off reduces stringing and glue tails to lower reject rates. Wear‑resistant valve core ensures stable long‑term intermittent dot or short‑strip output.

It applies to UV‑varnished or laminated gift‑box gluing, pharmaceutical carton folding, filter‑element edge sealing and precision light‑industry assembly. It suits folder‑gluer users suffering from frequent blockage and carbon deposit on ordinary hot‑melt guns.
