Theory of Linear Continuous Extrusion—Linex

LINEX is a friction actuated, continuous extrusion process for metals. It is fundamentally a linear continuous extrusion process using two-sided gripping of feedstock with the opposed sides being lubricated. The feedstock is carried into a unique die configuration called a diefork, where it upsets and develops sufficient pressure for extrusion. Basic design and theory of the process are presented, employing a new concept called modified force diagram to help explain the theory of process.
