Metal / Steel / Aluminum
High-adhesion Inkjet Marking System for Metal | Specially Designed for Oily & Rusted Working Conditions
Developed with molecular-level adhesion technology to fit complicated surfaces including plastic films, shrink packaging and injection-molded preforms:
- Customized Material-matched Inks: Quick-dry non-porous ink exclusively for PP, migration-resistant ink for PET, and food-grade water-based ink options.
- Dynamic Curved-surface Printing: Automatically synchronizes with rotary bottle filler speed to deliver high-DPI crisp marking on curved surfaces.
- Stable Performance Under Extreme Working Conditions: Printed marks remain intact from -20°C cold storage up to 80°C hot filling environments. Widely adopted for beverage caps, daily chemical packaging and medical tubing, eliminating common drawbacks of traditional coding such as easy abrasion and print deformation under high temperature.
Solutions:
Our industrial inkjet marking solution is specially customized for diversified metal processing and manufacturing lines. The coding equipment can be installed on stamping, cutting, polishing and automated metal assembly production lines, supporting high-speed inline continuous marking and offline batch static coding for small-lot orders. It effectively resolves core industry pain points including poor ink adhesion on smooth rust-proof metal surfaces, ink peeling caused by subsequent painting and high-temperature processing, as well as fuzzy printing on oily raw metal substrates, realizing full-process stable coding from semi-finished metal blanks to finished metal components.
Application Markets:
The coding system covers full-range metal manufacturing and downstream packaging industries. Typical applicable products include steel pipes, aluminum alloy profiles, iron hardware fittings, stainless steel spare parts, metal castings, stamped metal accessories, automotive metal components, metal fasteners and galvanized metal workpieces. It widely serves construction hardware, auto parts manufacturing, machinery processing, metal container fabrication and valve production sectors.
Printable Substrates:
Compatible with mainstream metallic substrates, including stainless steel, carbon steel, aluminum, copper, iron, galvanized sheet, zinc-plated metal and polished smooth alloy surface, as well as oily unfinished raw metal and rust-proof coated metal parts. Specially-formulated ink and printing parameters are optimized for dense non-absorbent metal texture, avoiding ink shrinkage, droplet beading or detachment even on polished glossy metal without pre-grinding or surface primer treatment.
Printing Content:
It supports flexible coding of fixed and variable information on metal surfaces, including production batch numbers, manufacturing dates, component model codes, factory serial IDs and supplier trace codes. Apart from regular text and numerals, the machine realizes high-precision printing of one-dimensional barcodes, QR anti-counterfeit codes, brand logos and customized specification marks. All variable printing data can be imported from multi-source databases for real-time editing and batch variable-data marking.
Ink Features:
- Strong Adhesion: Specially-formulated metal ink tightly bonds with dense smooth metal surfaces, resisting peeling or falling off after paint spraying, high-temperature baking and long-term outdoor exposure.
- High Definition & Fine Printing: Delivers ultra-clear tiny character printing, suitable for precise fine marking on miniature metal fittings and precision machined parts.
- Scratch & Wear Resistance: Printed marks withstand daily friction, mechanical assembly collision and long-term outdoor abrasion to maintain permanent legibility.
- Temperature & Humidity Resistance: Stays intact under high-temperature baking, low-temperature storage and damp outdoor working environments without fading or blurring.
- Fast Drying Performance: Instant drying right after printing to prevent smudge on high-speed continuous metal production lines.
- Diversified Ink Options: Multiple ink selections including black, white, high-temperature resistant ink, solvent-based anti-rust ink and anti-corrosion special ink to satisfy diverse metal marking demands.
Importance of Component Marking:
- Product Specification Identification
Since metal spare parts share similar outer appearances while differing greatly in specifications and material grades, direct surface coding of model parameters enables quick and error-free specification sorting during incoming inspection and inventory management.
- Guiding Customer Choice
Clear printed product information conveys production standard and product quality to purchasers, helping clients make reliable procurement decisions and pick qualified metal products.
- Full Lifecycle Traceability
Unique coded marks realize full-chain traceability covering raw metal smelting, mechanical processing, finished product storage and terminal delivery, supporting precise quality tracking and efficient after-sales recall management.
- Brand Reputation Protection
Standard permanent marking prevents counterfeit inferior metal parts from flooding the market, effectively safeguarding manufacturer’s intellectual property and brand market credibility.
- Anti-Counterfeiting Security
Encrypted QR codes and exclusive anti-fake markings allow end clients to verify product authenticity rapidly, protecting both brand profit and end-user benefits.
- Market Expansion & Sales Growth
Durable neat metal marking acts as credible quality certification, lifting customer purchasing confidence, boosting purchase intention and driving continuous market share expansion and sales growth.
