KQ‑HP30A is a  Direct‑nozzle plasma activation machine, tailor‑made for linear straight cartons, double‑wall cartons, double‑sided edge pasting, large glue flaps and self‑locking bottom boxes. It covers multiple industrial sectors including packaging printing, 3C electronics, automotive manufacturing, furniture, wire & cable, inkjet coding and 3D printing. Its core packaging application solves frequent delamination and bubbling failures on cartons coated with UV varnish, PET lamination and gold/silver metallic layers. After narrow Direct‑nozzle plasma pretreatment, manufacturers can adopt economical standard cold glue instead of high‑cost special adhesives, greatly cutting long‑term glue procurement expenses for medium‑high volume folding box production lines.

Outside packaging, it supports synchronous three‑channel narrow strip surface activation before gluing, printing and coating. In automotive manufacturing, it processes three groups of parallel narrow plastic interior strips and cable insulation surfaces at once to enhance bonding durability. For 3C electronics, it treats three bonding edges of mobile glass and circuit boards simultaneously to avoid ink peeling and sealing gaps. Furniture factories use it on three narrow wood veneer edges to upgrade lamination flatness and bonding strength.

The mobile cabinet unit can be mounted inline on folder gluers, carton makers and coding lines, running stably at a maximum carton speed of 20 m/min. Each Direct‑nozzle delivers adjustable narrow treatment width of 6‑10 mm, capable of handling three glue flaps on one carton or three separate workpieces synchronously. Interchangeable Direct‑nozzles match diverse narrow bonding edges, and universal red casters support flexible layout adjustment for medium‑high output automated box lines.

The core competitive strength of KQ‑HP30A lies in its three independent Direct‑nozzle design, tripling processing efficiency compared with single/dual Direct‑nozzle plasma models (KQ‑HP10A/20A), perfectly matching factories producing self‑locking bottom boxes, double‑wall cartons and multi‑flap straight cartons in large batches. The focused low‑temperature plasma jet targets only narrow glue flaps without energy waste, lifting substrate surface tension above 40 mN/m to fully eliminate peeling, bubble and poor adhesion defects. It replaces traditional mechanical polishing and scoring, producing zero paper dust and surface scratches while protecting printed, UV and metalized coating layers to maintain premium product appearance.

It effectively lowers overall production costs: post‑plasma treatment, cheap ordinary cold glue can replace expensive dedicated hot melt adhesives. Direct‑nozzles contain no rotating moving parts; contactless plasma jet creates no thermal damage to thin paper, plastic film and delicate coated substrates. Equipped with multi‑layer safety interlock switches, real‑time fault alarm and three‑color running indicator light, the machine has passed EU CE certification to meet export standards for European and American markets.

The integrated mobile cabinet measures 600(W)*400(D)*1000(H) mm with net weight 60 kg, fitted with universal moving casters for quick on‑site line refitting. It adopts three independent power modules with total power of 2400VA (800VA per nozzle) and compressed air demand of 0.4‑0.6 Mba. Compared with multi‑nozzle rotary plasma equipment, Direct‑nozzle structure has fewer vulnerable components, simpler daily maintenance and lower spare part replacement costs, making it a cost‑effective choice for multi‑flap straight box mass production.
