Marking Applications for Industrial Markets


  • 1. MarkingTechnologies For Industrial Markets

2. About Matthews Over 150 years in business Supplier of etching,indenting, contact printing,ink-jet printing and lasermarking products Ink developer with ISO 9001certification Industrial applications areour primary focus 3. Four reasons to mark Primary identification Traceability Compliance Operational 4. Primary identification Company name and trademarks Part numbers Size 5. Traceability Serial numbers Time and datestamps Batch codes Bar codes 6. Compliance Government control:tax, country of origin Associations: glass,steel, environmental Vendor specification:automotive companies Bar codes for inventory 7. Operational marking Orientation or location marks Inspection Color codes Instructional Bar codes to facilitate automation 8. Methods of marking Printing Adds color and contrast using ink Indenting Most permanent by material displacement Etching Removes the surface Labeling/Tagging Attaches the mark to the product 9. Printing methods Used when color or contrast is required Contact Printing (Uses dye and pigmented inks) Offset (glass, rubber hose, plastic profiles) Direct (metal sheet, flooring, plastic film) Reciprocating (packaging, autoparts, tires) Ink-Jet Printing DOD, Drop-on-Demand (packaging, steel, lumber, plastic pipe) Impulse (packaging, light industry) CIJ, Continuous Ink-Jet (packaging, plastic pipe, steel, glass) 10. Contact printing Offset printing Offset ink in an ink fountain is picked up by a rotating ink roll. Before the ink is transferred to a type wheel, it is metered to a desired film thickness by a doctor blade. After the type wheel is inked, an impression of the legend is transferred to the blanket roll which marks the product. Direct printing The characters or type wheel comes in direct contact with the surface of the product being marked. 11. Contact printing benefits Pigmented inks fit a widevariety of markingapplications Superior print quality Economical, reliableoperation In-line and stand aloneapplications 12. Ink-Jet printing Drop-on-demand A column of ink droplets are fired together toform a printed character while the substratemoves. Impulse A series of 32 openings/nozzles in theprinthead are channeled into 96-352 holes.Using sound waves, the ink is moved fromopenings to the product. No pressurized inksystem or mechanical valves are used tomove the ink to the product. Continuous Ink-Jet A single stream (continuous) of ink ismodulated or broken into droplets of ink.Each droplet is electronically charged anddirected by a magnetic field to form intocharacters as it is sprayed onto a movingsubstrate. 13. Ink-Jet printing benefits Fast messagechangeover High speed marking Reliable, simpleoperation Uneven surfacemarking ok High-quality printingof text and logos 14. Indenting Methods Used when permanence is a must! Especially for the tools and transportation industries. Hand marking Inspection marking, portable method In-line systems-example: packaging type Part of the fabrication and forging process Impact press Stand alone or in-line, with same legend Rollmarking Stand alone method providing deep marks Stylus Versatile, variable text and character size Low stress method, can be automated Marks harder materials (50 RC) 15. Indenting Benefits Permanent productidentification on a widerange of materials Simple, reliable markingmethod Accommodates a variety ofproduct shapes and sizes Easy operation & minimalmaintenance 16. Etching methods Used on glass & polished metal products. Acid Etching Polished metal, inspection only-appliedwith a vinyl inspection stamp. Airgrit Dry Etching Automotive, flat glass, lenses-also workson polished metals as an alternative toelectro-chemical etching. Laser Marking Packaging, automotive, metals,plastics, offers variable text forserializing. 17. Airgrit Etching solutions Bench-Top models Under-Line table top models Large, portable models 18. Airgrit Etching benefits High-quality frostedimpressions in afraction of a second Less than a penny permark Safe, permanentidentification withoutacids or chemicals Easy operation andminimal maintenance 19. Labeling & tagging Used when it is not practical to mark the product itself. Label printer applicators Packaging, multiple line legendswith UPC bar codes Embossed tags Tire date codes, jet enginere-builders, steel distribution Nameplates Motors, fabricatedmetal,machine builders 20. The best method for youConsider these questions What is the product you need to mark? What is the products size and shape? What is the material and hardness? What color? 21. The best method for youConsider these questions Surface condition? Temperature during marking? Environment the product will exist in? Usage of the marked product? 22. The best method for youConsider these questions How large or small do the marks need to be? How many lines of print do you require? What color should the mark be? How will the mark be read?(bar code scanner, humans) 23. The best method for youConsider these questions Production rate at which the productmust be marked? Is the product stopped or moving? How much space is available within yourproduction line? What is the printer orientation?(over, under, side) 24. ConclusionsThere are 4 basicThere are 4 basicreasons for marking: methods of marking: Primary identification Printing Traceability Indenting Compliance Etching/Laser Operational Labeling/Tagging 25. ConclusionsDetermine the best method for your application: Know your current process. What is your reason for marking? Consider productivity improvements. (automatedprocesses, improved mark legibility) Any room for lowering operating expenses, is this desired? Determine the usage of your product. (longevity of marks,special ink requirements, outdoor storage, etc.) Seek advice from experts in the field of identification. 26.
