Ceramic Inkjet Marking

High-temperature Resistant Ink for Automated Coding

Marking on ceramic substrates, especially ceramic catalyst components, poses prominent technical challenges. Lanyin’s non-contact inkjet technology fulfills strict full supply chain marking requirements for diversified ceramic products.

Solution:

LION TEC tailor-made industrial inkjet marking solution is professionally developed for high-temperature ceramic production and post-processing lines. Equipped with non-contact ejection structure and high-temperature resistant ink supply system, the coding equipment supports stable high-speed inline marking on kiln-front green ceramic blanks and offline marking on sintered finished ceramic parts. It overcomes core industry difficulties including ink fading after high-temperature firing, poor adhesion on dense glazed ceramic surfaces and fuzzy printing on porous catalyst ceramic, realizing consistent permanent marking across full ceramic production chain.

Application Markets:

The marking system covers multiple ceramic manufacturing segments. Typical applicable products include automotive exhaust ceramic particulate filters, industrial ceramic catalysts, precision electronic ceramic components, ceramic insulating parts, daily glazed ceramic ware and building ceramic accessories. It widely serves auto exhaust component factories, new energy catalyst manufacturers, electronic ceramic processing enterprises and sanitary ceramic producers.

Printing Materials:

Compatible with various ceramic substrates: unsintered green body ceramic, high-temperature sintered dense ceramic, glazed smooth ceramic, porous catalyst carrier ceramic, matte unglazed ceramic and special modified industrial ceramic. Specially formulated high-temperature resistant ink and optimized printing parameters adapt to both porous loose ceramic texture and compact impermeable glazed surface without ink shrinkage, crawling or peeling after subsequent high-temperature heat treatment.

Printing Content:

The machine enables flexible printing of fixed and variable information on ceramic surfaces, including production batch codes, furnace serial numbers, component model IDs, production dates and raw material batch numbers. Apart from regular texts and numeric data, it delivers high-precision Direct Part Marking (DPM) such as Data Matrix codes, traceable QR codes and exclusive anti-counterfeit graphic marks. All variable production data can be imported from multi-source databases for real-time modification and batch variable-data coding.

Ink Features:

  • Strong High-temperature Resistance: Specially calcination-resistant ink keeps intact without fading or falling off after high-temperature kiln sintering.
  • Strong Adhesion: Firm bonding with both porous ceramic base and smooth glazed ceramic to resist long-term abrasion and environmental corrosion.
  • High Definition & Fine Printing: Produces ultra-sharp tiny characters and micro codes for compact marking on miniature precision ceramic components.
  • Scratch & Chemical Resistance: Printed marks withstand wiping, solvent cleaning and harsh working environment without blur.
  • Fast Drying Performance: Instant surface drying after ejection to avoid ink smudge during continuous automated ceramic conveying.
  • Diversified Ink Options: Available with high-temperature calcination ink, black/white pigment ink, food-safe ink and anti-corrosion specialty ink matching different industrial and daily ceramic standards.

Importance of Component Marking:

  • Product Specification Identification

    Ceramic parts feature highly similar appearance while differing greatly in sintering craft, material grade and application specification; directly printed batch and model data enables rapid error-free sorting during incoming inspection and finished goods inventory management.

  • Guiding Customer Choice

    Clear permanent printed specification and certification information helps purchasers identify qualified ceramic products and make accurate procurement decisions.

  • Full Lifecycle Traceability

    Unique coded markings realize end-to-end supply chain traceability covering ceramic raw material blending, green body forming, high-temperature sintering and finished product delivery, supporting precise quality tracking and targeted defective batch containment.

  • Brand Reputation Protection

    Durable anti-high-temperature marking prevents counterfeit inferior ceramic components from entering market and effectively safeguards manufacturers’ intellectual property and brand credibility.

  • Anti-Counterfeiting Security

    Encrypted Data Matrix and exclusive anti-fake imprints allow instant authenticity verification to protect both brand profit and end-user application safety.

  • Market Expansion & Sales Growth

    Stable high-quality permanent marking acts as credible quality certification, lifting customer trust and purchase intention to drive continuous sales growth and market share expansion.
