Digital Touchscreen HMI: Real-time monitoring of power output, voltage, frequency, line speed, and fault diagnostics.
Micro-Gap Adjustment: Precise mechanical micrometers allow operators to set exact air gap distances down to 0.1 mm accuracy.
Integrated Ozone Extraction Port: Direct connection points for plant exhaust systems to instantly evacuate ozone and process byproducts safely.
Quick-Thread Design: Open-hinge or split-shell housing allows seamless thread-up of continuous tubing during line startup.
Product Applications
Plastic Pipe & Tubing
Surface activation for inkjet coding adhesion on PVC, PE, and PP irrigation and plumbing pipes.
Medical Tubing & Catheters
Modifying inert fluoropolymer or silicone surfaces prior to solvent bonding or secondary printing.
Automotive Profiles
Preparing rubber and thermoplastic elastomer weatherstripping and hoses for flocking, gluing, or adhesive taping.
Cable & Wire Insulation
Pre-treating outer insulation layers before ink marking or jacketing.
System Configuration
High-Frequency Generator Unit
Solid-state inverter producing stable output frequencies between 20 kHz and 30 kHz.
Treatment Station Assembly
Fully enclosed stainless-steel chamber housing the high-voltage electrodes and dielectric rolls.
Exhaust Blower & Ozone Decomposer
Optional neutralizing unit to convert ozone back into oxygen before releasing air into the plant.
Isolation Transformer
Protects internal circuitry from plant grid voltage fluctuations and electrical noise.
How it Works
Electrical Ionization
The solid-state generator applies a high-frequency, high-voltage potential across an air gap between the powered electrode and the grounded support roll.
Corona Discharge Generation
Air molecules in the gap ionize, creating a controlled electrical discharge plasma curtain.
Substrate Passage
The extruded tube passes through the plasma field. Free electrons and ionized gas molecules bombard the polymer surface.
Surface Energy Modification
Molecular bonds on the polymer chain break, allowing polar functional groups to graft onto the surface, raising surface energy measured in dynes per centimeter.
Material Compatibility
Polyethylene
High-Density Polyethylene, Low-Density Polyethylene, and Linear Low-Density Polyethylene.
Polypropylene
Extruded profile and homopolymer or copolymer grades.
Polyvinyl Chloride
Rigid and flexible pipe grades.
Engineering Plastics
Polycarbonate, Acrylonitrile Butadiene Styrene, and Polyamide or Nylon.
