Corona treatment machine price

When sourcing a corona treatment machine, you must prioritize the Output Power (kW) and Treatment Width. Ensure the power generator is equipped with IGBT modules for stable high-frequency discharge. For film blowing or printing lines, verify the dyne level capability (typically aiming for 38-42 dynes/cm for standard PE/PP). Additionally, check if the discharge rack uses ceramic electrodes (ideal for conductive materials like aluminum foil) or silicone/stainless steel electrodes (standard for non-conductive films).

A professional-grade machine must include an Ozone Exhaust Blower to safely remove ozone generated during the ionization process. Look for features like Auto-Stop protection when the web stops moving to prevent film burning, and High-Voltage Spark Protection. Compliance with CE certification is mandatory for European markets, ensuring the electrical components meet international safety standards.

The price is primarily driven by the generator power (1kW to 20kW+) and the automation level. Investing in a system with an Automatic Speed-Power Adjustment feature can be more cost-effective in the long run as it reduces material waste during line speed changes. For B2B buyers, sourcing from Made-in-China.com allows for comparing factory-direct pricing, which typically offers a 20-40% cost advantage over local distributors while maintaining high-end component integration.

Usage scenarios vary by industry: Extrusion coating lines require high-power stations for thick substrates, while Flexographic or Gravure printing requires narrow-web treaters for ink adhesion. If you are in the Laminating industry, ensure the machine supports double-sided treatment. For specialized applications like hollow sheet or pipe treatment, custom-shaped electrodes are necessary.

Always request a Video Factory Audit and a Live Running Test of the specific unit before final payment. Use Trade Assurance services available on Made-in-China.com to secure your funds until shipping documents are verified. It is also critical to hire a third-party inspector (like SGS or Intertek) to verify the electrical wiring and discharge stability before the machine leaves the factory.

Focus on the Total Cost of Ownership (TCO) rather than just the sticker price. Negotiate for extra sets of wearing parts (like silicone sleeves or electrodes) to be included in the initial price. For bulk orders or long-term partnerships, ask for a 2-year warranty instead of the standard 1-year, and confirm the availability of remote technical support via video call.

Corona generators contain sensitive electronics and high-voltage transformers. Ensure the supplier uses Vacuum Packaging and Fumigated Wooden Crates to prevent moisture damage and physical impact during sea freight. Specify CIF or DAP incoterms if you prefer the supplier to handle the complex logistics, but ensure the Insurance Policy covers the full replacement value of the equipment.

Before finalizing the contract, explicitly state your local Voltage (e.g., 220V, 380V, 415V) and Frequency (50Hz or 60Hz). Many Chinese machines are standard 380V/50Hz; if your region differs, the supplier must install a custom transformer or adjust the generator's internal circuitry to prevent immediate equipment failure upon installation.
