In the fiercely competitive metal manufacturing and processing industry, every piece of galvanized sheet is not only a foundational material for applications such as construction, home appliances, and automobiles, but also bears the weight of a company’s brand and quality commitment. Clear, durable, and efficient marking is crucial for achieving traceability, anti-counterfeiting, and brand recognition. However, traditional inkjet coding technology often encounters challenges with the smooth, non-absorbent surface of galvanized sheet, such as poor adhesion, easy shedding, and easy removal with solvents such as alcohol.
The emergence of the CYCJET CH702 UV inkjet printer provides a perfect solution to this industry pain point, and redefines the new standard for galvanized sheet marking with its excellent performance.
Challenges and Breakthroughs: Why Does Galvanized Sheet Metal Need a Dedicated Coding Solution?
Galvanized sheet metal has a dense, smooth surface, often coated with an oily film. This poses significant challenges for ink adhesion. Ordinary inks are difficult to penetrate, and printed markings often rub off or wear away during subsequent handling, storage, and processing, resulting in information loss and significant challenges for quality traceability and product management.
The CYCJET CH702 UV inkjet printer addresses this challenge head-on. Its core advantage lies in its advanced ultraviolet curing (UV) technology. This technology achieves permanent adhesion through a chemical reaction, rather than relying on surface absorption.

Core Advantages of the CYCJET C702 UV Inkjet Printer
- Superb Adhesion and Durability
The CH702 uses a specially formulated UV ink. After printing on a galvanized steel surface, it is instantly irradiated by an internal or external UV lamp. The photosensitive components in the ink undergo a cross-linking and curing reaction, transforming from a liquid to a solid state. This process creates a mark that is not only scratch- and abrasion-resistant, but also effectively resistant to chemical solvents such as alcohol, gasoline, and thinners. Even in oily production environments, the mark remains as clear as new, ensuring product traceability throughout its lifecycle.
- High-resolution printing comparable to printed matter
Traditional inkjet printers have limited resolution, and printed content is mostly dot-matrix, which lacks aesthetic appeal. The CYCJET CH702UV boasts an industrial-grade resolution of up to 360 dpi, enabling the printing of crisp, clear text, complex and varied QR codes, barcodes, and intricate logos. This is crucial for galvanized sheet products that strive for a strong brand image and carry extensive data, significantly enhancing the product’s professionalism and added value.
3. Non-contact printing, no damage to the material
The CH702 utilizes non-contact printing technology, with the printhead making no physical contact with the galvanized sheet surface. This completely eliminates potential scratches, deformation, or indentations that could otherwise occur, perfectly protecting the galvanized sheet’s coating and surface quality. It is particularly suitable for high-end galvanized sheet products with extremely demanding surface finishes.
- Efficient and stable, enabling intelligent production
The device operates rapidly, easily adapting to high-speed production lines for uninterrupted online coding. Furthermore, its intelligent operating system seamlessly integrates with production management systems such as MES and ERP, automatically capturing and printing variable data (such as production date, batch number, serial number, etc.). This significantly reduces manual intervention, lowers error rates, and improves overall production efficiency and intelligent management.
三、 Application Scenarios: Ubiquitous Excellence
Whether it’s galvanized coils leaving large steel mills or finished parts after shearing and stamping, the CYCJET CH700UV inkjet printer can perform effectively:
- Traceability Management: Prints a permanent QR code, enabling accurate traceability from production to end-user.
- Brand Display: Prints your company logo and brand name prominently on the sheet metal, creating a mobile billboard.
3. Production Management: Marks specifications, dimensions, batch sizes, and other information to facilitate warehouse management and production scheduling.
In short, the CYCJET CH702 UV inkjet printer is more than just a coding device; it’s a strategic tool for the galvanized sheet industry to improve product quality, strengthen management, and cultivate a high-end brand image. It harnesses the power of technology to transform fleeting information into a lasting imprint, providing solid technical support for the industry’s digital transformation and high-quality development. Choosing the CYCJET CH702 UV printer means choosing reliability, efficiency, and excellence. Let’s work together to give each of your galvanized sheets a clear and lasting “identity.”
