Hefeng solutions at the heart of invisible performance
1. Perfect printing starts at the surface
Before a single drop of ink touches the substrate, everything is already decided… at the surface.
Adhesion, uniformity, gloss, durability — all these parameters depend on a factor that’s often invisible yet absolutely decisive: the surface energy of the material.
Plastic film, synthetic paper, aluminum, PET, PE, PP… all these substrates share one trait: their surface is naturally “closed,” meaning it’s not very receptive to inks, varnishes, or adhesives.
That’s where surface treatment technologies come in — Corona, Plasma, and Antistatic.
True guardians of quality, they prepare the substrate to receive ink just as one primes a canvas before painting.
2. Corona treatment: controlled energy
Corona treatment is the most widely used technology in the label and packaging industries.
Its principle is simple: it creates a controlled high-frequency electrical discharge between an electrode and a grounded roller, altering the surface tension of the material.
This micro-discharge oxidizes the outer molecular layer of the substrate and increases its surface energy (typically from 32 to 44 dynes/cm).
Results:
✅ Better ink spreading,
✅ More uniform drying,
✅ Strong, long-lasting adhesion — even at high speed.
The Hefeng systems are among the most reliable on the market:
- automatic power adjustment,
- air- or water-cooled electrodes,
- high-frequency generators with self-diagnostics,
- easy integration on Spande, SMAG-X, GIP, or Wanjie Europe presses.
“Corona is the guarantee of a successful first impression.”
3. Plasma treatment: the new generation
When substrates become more technical — multilayer films, conductive or ultra-thin materials — Corona reaches its limits.
That’s where Plasma treatment comes in: gentler, more precise, and suitable for a wider range of substrates.
Cold Plasma generates a cloud of highly reactive ions at low temperature, chemically activating the surface without damaging it.
Advantages:
- perfectly uniform treatment, even on textured or uneven surfaces,
- no ozone generation,
- reduced energy consumption,
- full compatibility with sensitive materials.
Hefeng Plasma stations are particularly suited to Spande AC lines.
“Plasma is the future of surface treatment: efficient, eco-friendly, and intelligent.”
4. Antistatic control: invisible stability
Another often-overlooked source of printing errors at high speed is static electricity.
It attracts dust, deflects ink droplets, disrupts sensors, and causes unpredictable defects.
Hefeng ionizing bars neutralize these charges before they cause trouble, ensuring:
- a clean and stable web,
- consistent print quality,
- improved operator safety.
When combined with Hefeng web-cleaning systems (contact or non-contact), they deliver maximum productivity and a measurable reduction in waste.
5. MachGlobal integration: mastering the complete process
At MachGlobal, surface treatment is considered a strategic step, on par with printing or inspection.
That’s why we integrate Hefeng solutions at the heart of our complete production lines:
- Spande presses for flexo printing,
- Wanjie presses for offset printing,
- SMAG-X presses for screen printing,
- SMAG-X I-Convert and I-Concept finishing modules,
- GIP inkjet presses.
Each installation is designed to ensure the perfect balance between quality, productivity, and reliability — backed by European technical support.
We also retrofit all brands of presses with Hefeng systems.
“A beautiful print always starts with a well-prepared surface.”
— Stéphane Rateau, MachGlobal Connect

7. Conclusion: the surface — foundation of quality
People often talk about inks, varnishes, or inspection cameras.
But without a controlled surface treatment, none of these technologies can deliver their full potential.
Corona, Plasma, and Antistatic are not accessories.
They are the invisible foundations of print quality — and, ultimately, of every printer’s reputation.
With Hefeng and MachGlobal, these technologies become accessible, reliable, and perfectly integrated into the European printing environment.
They embody one shared conviction:
Perfection lies in the details you can’t see… but that your customer can feel.
