The Extrusion Process
There are several different extrusion methods. Direct and indirect extrusion are semi-continuous extrusion processes that take a variety of factors into consideration, including ingot weight, extrusion weight, extrusion profile length and cycle authorisation times.
ProfilGruppen uses Direct Extrusion.
There are also continuous extrusion processes, which are only used for small extrusions and simple pipes. However, the one thing all extrusion processes have in common is that the shaping process occurs during the brief moment the material passes the shaping pin in the tool. This is central to all extrusion pressing.
In order to secure a process with a sustainably high level of accuracy, tools must be precisely adjusted and utilised. In addition, process parameters must be carefully checked in order to ensure a high level of quality in production.
The extrusion process affords considerable freedom to the design of various extrusion cross-sections. At the same time, both the process and tool production are subject to a number of limitations.
