Although after the transient startup phase the process of cold extrusion is classed as steady-state, in reality, due to changing contact conditions and in process temperature variation this is not accurate.
There are however a wide range of useful benefits from cold extrusion including elimination of welding connections, flexibility of branch positioning, seamless metallurgical integrity and extended service life of the materials to name but a few.

Hydro-forming Process of Steel: Part Two
The Tube Hydroforming (THF) process is a relatively new manufacturing technology, which has been used in the past decade. THF offers potential alternatives in the use of lightweight materials and hence can have a great impact in saving energy in the automotive industry.
THF offers several advantages as compared to conventional manufacturing via stamping and welding.
Hydro-Forming Process of Steel: Part One
One of these new processes is tube hydroforming and although the development of this process for the automotive industries is relative new, many process variables have been studied, including; friction, material properties, pressures and the displacement path during the process.
Hydroforming uses fluid pressure in place of the punch in a conventional tool set to form the part into the desired shape of the die.
