Linear cage forming tube mills produce variety of sizes without roll changes.

COPRA RF CageForming provides all necessary tools to create roll cages for the so-called linear cage forming process. Our custom developed module is a versatile tool for producers of longitudinally welded tubes to develop roll tooling for various different tube diameters with minimized tool changes.


In session 11 of our COPRA Virtual Conference series Lander Arrupe will introduce you to the world of Cage Forming.

In this conference we will demonstrate how versatile this tool is, specially together with COPRA FEA RF for the verification.

  • We will show you the Cage Forming Interface in COPRA RF
  • You will also see how the FEA model will be prepared automatically
