KQ-HP20B is a dual-nozzle rotary plasma activation equipment, widely deployed in packaging printing, 3C electronics, automotive parts, furniture, wire & cable, inkjet coding and 3D printing industries. Its core application solves poor adhesion for cartons covered with UV varnish, PET lamination and metallic gold/silver coating, materials that easily bubble and delaminate after gluing. After plasma activation, manufacturers can adopt low-cost standard cold glue instead of expensive special adhesive, delivering stable bonding for gift boxes, cosmetic packaging, wine boxes and pharmaceutical cartons.

For non-packaging manufacturing sectors, it activates plastic, glass, composite and metal workpieces to boost adhesion for gluing, printing and coating procedures. In automotive production, it treats plastic interior parts and cable insulation surfaces to enhance bonding durability. For 3C electronics, it processes mobile glass, circuit boards and precision plastic components to eliminate ink peeling and sealing gaps. Furniture factories apply it on coated wood panels to optimize veneer lamination performance.

This machine supports inline installation on folder gluers, carton makers and coding production lines, operating stably at a maximum carton running speed of 20m/min. Equipped with two independent rotary nozzles, each nozzle covers adjustable 30–54mm treatment width, enabling synchronous dual-position processing to double production capacity. Interchangeable rotary nozzles match various workpiece sizes, and the mobile cabinet with casters facilitates flexible layout transformation for mass continuous automation lines.

The core competitive strength of KQ-HP20B lies in its dual rotary nozzle design, realizing double independent plasma treatment channels to significantly lift line throughput compared with single-nozzle plasma models. Rotary jet delivers wider, more uniform surface activation coverage without blind spots, raising substrate surface tension above 40 mN/m to thoroughly solve carton peeling, bubble and poor adhesion defects. It replaces traditional mechanical polishing and scoring processes, generating no paper dust or surface scratches and keeping printed, UV and metalized layers intact to maintain premium product appearance.

It greatly reduces long-term production costs: post-plasma treatment, ordinary economical cold glue can replace high-priced dedicated hot melt adhesives. The low-temperature contactless plasma jet causes no thermal damage to thin paper, plastic film and delicate coated surfaces. Equipped with multi-layer safety interlock switches, real-time fault alarm and three-color status indicator light, it passes EU CE certification to meet global export safety standards.

The complete mobile cabinet structure (600×400×1000mm, net weight 55kg) with universal casters supports free movement and quick inline refitting. It adopts dual independent power modules with total power of 1600VA (800VA per nozzle) and matched compressed air demand of 0.3–0.4 Mba. Multiple interchangeable rotary nozzles are available for flexible width adjustment, simplifying mold switching for multi-variety high-volume production workshops.
