Advanced metallurgy. Precision engraving.

Features

Advanced metallurgy:

  • No short-lived conventional copper compositions. If a diameter needs build up, Steel / Stainless steel is used, which extends the lifetime. After the engraving the roll receives a special chrome coating.

High precision:

  • Tightest T.I.R. & O.D. and an even screening over the entire engraved surface for a constant screen, volume, depth, wall and angle.

Precision Engraving:

  • Multi-pass mechanical knurling. Special tools enable to engrave directly into steel / stainless steel.

Advanced engravings:

  • Standard & New engraving patterns including finer line screens (from 6 l/cm to maximum 140 l/cm. The patterns manufactured are: 45°, Hexagonal, Tri-Helical, Channellox or specials on request.
  • Special tools enable Apex to engrave directly into steel or even stainless steel
  • Different cell specifications and patterns available
  • From 6 l/cm up to 140 l/cm
  • Standard 30°45°and 60° as well as custom engraving options;
  • Quadrangular, Pyramid, Hexagonal, Tri-Helical,
  • Channellox or specials on request.
  • AST metal fusion process for original diameter
  • Build up with steel
