  • Radiography (X-ray and Gamma)

  • Ultrasonic Examination

  • Positive Material Identification (PMI)

Labelling & Tagging

Adanac has Computer-Aided Electronic Engraving equipment and produces metal tags and labels to meet customers' product identification marking requirements. Our Edward Prior dot marking machine allows the marking of text and simple logos on pre-cut tags and labels. Blank tags and labels are accurately produced by either laser or Water-Jet cutting for small—medium volumes. Larger volumes may be produced by stamping.


  • Common information can be screen printed or etched where required, allowing the addition of the customer's individual order/product specific information to be added by dot marking.
  • Tags and Labels may be attached to the product by a variety of means including wound and crimped wire, nylon tie, blind rivet and spot weld.
