Working with metal cans & parts
Metal covers beverage cans, closures, foil and machined components. Surfaces range from bare and oily to lacquered and anodised, and many marks must be permanent.
Practical tips
- On anodised aluminium a MOPA source gives the darkest mark without breaking the anodic layer.
- Remove oil films before inkjet printing or choose an oil-penetrating ink.
- For medical stainless steel, use annealed marks rather than deep engraving to preserve corrosion resistance.
What works, and why
Fiber Laser Marking Machines
Anneals, engraves or ablates coatings — the first choice for permanent marks on metal.
Continuous Inkjet (CIJ) Printers
Fast, economical dating on can bases and closures, including retort-resistant inks.
UV Laser Marking Machines
Fine marks on coated metals and sensitive finishes.
Vision & Code Inspection Systems
Verifies direct part marks and date codes.
