Why Buyers Choose It
Key Benefits
- 3KW output power delivers consistent surface energy treatment across 360mm width, reducing print and coating failures
- Ceramic square electrode tubes (15.2 x 16 x 2.5mm) resist wear and maintain stable output over time
- 15-25KHZ frequency range allows tuning for different material types and coating adhesion requirements
- 6 electrode tubes arranged in 390mm lengths provide uniform treatment across the full process width
- Output voltage range of 8000-12000V ensures effective surface activation on low-energy plastics and films
- Configured to your process width and material type, reducing trial and error in production
- Pre-shipment inspection ensures electrical and mechanical function before shipment
Problems It Solves
- Inconsistent adhesion of ink, glue or coating due to low surface energy on plastic or film
- Manual surface treatment methods that vary by operator and cause batch-to-batch inconsistency
- Lack of a dedicated corona system in small or mid-sized production lines
- High failure rates in printing or lamination due to untreated or under-treated surfaces
- Difficulty finding a factory that can supply and integrate a corona treater with correct specs
- Unreliable units from unknown suppliers that fail after a few weeks of operation
Where It Is Used
Who It Is For
- Industrial packaging converters sourcing equipment for film or foil treatment
- Printing houses expanding into flexible packaging with a need for surface activation
- Contract manufacturers requiring a turnkey corona system for client production
- Equipment integrators building automated lines that include surface treatment
- Manufacturers of plastic components needing consistent adhesion for labels or coatings
- Sourcing teams in industrial equipment or materials processing who need a reliable supplier
Application Scenarios
- Plastic film lamination lines where print adhesion fails due to low surface energy
- Flexible packaging lines requiring consistent label adhesion on polypropylene or polyester
- Coating application on foil or film where primer bond strength is inconsistent
- Printing operations on non-porous materials such as PVC, PE, or PET where ink lifts
- Contract manufacturers needing a reliable, factory-integrated corona system for client work

How It Is Made
- We confirm your process width, material type and required output parameters before sourcing
- The factory we work with builds the unit with 6 ceramic electrode tubes aligned to 390mm length
- Electrical components are assembled and tested for voltage stability and frequency output
- Control system is calibrated to maintain consistent output across the 15-25KHZ range
- Final function test checks voltage, frequency, and uniformity across the 360mm width
- Unit is inspected before shipment and shipped ready for installation
Quality And Use
Quality Control
- Product details and configuration confirmed before mass production starts
- Production followed through electrode assembly, electrical integration, and system testing
- Each unit inspected before shipment for electrical function and mechanical integrity
- Output voltage and frequency tested across the full range to ensure consistency
- Issues after receipt are handled directly with the sourcing contact who ran the order
Use Guide
- Install the unit on a stable surface with adequate ventilation and clearance around the electrodes
- Set output voltage and frequency based on your material and coating requirements
- Run a test strip of your material through the system and check adhesion quality
- Adjust voltage or frequency if the surface energy is too low or too high
- Clean electrode tubes regularly with a soft brush and dry cloth to prevent residue buildup
- Do not touch the electrode tubes during operation or when powered
- If the unit fails to start, check power supply, fuses, and grounding
How It Compares
| Compared with | Honest trade-off |
|---|---|
| Manual corona treatment with handheld unit | Higher consistency and throughput, but requires a fixed installation and higher upfront cost |
| Low-power corona system under 2KW | Lower output may not treat wide or low-energy materials effectively, but uses less power |
| Corona system with metal electrodes | Ceramic electrodes last longer and resist degradation from corona discharge |
| Generic unit from unknown supplier | This unit is sourced with verified specs and inspected before shipment, reducing failure risk |
Questions About This Product
What is the minimum order quantity?
MOQ differs by product and usually falls between 200 and 1000 pcs. We confirm the exact figure with the factory when we quote.
Can we adjust the output voltage and frequency?
Yes. The unit is designed to allow adjustment within the 8000-12000V and 15-25KHZ range for different materials.
Can we get a sample first?
Samples are free when the total sample value is under 5 US dollars and you have a DHL, UPS, TNT or FedEx account and cover the courier freight.
How does payment work?
30% deposit before mass production and the balance before shipment. T/T is our usual method; ask us if you need another arrangement.
