Extruded graphite is a type of graphite material produced through a process called extrusion.
This involves forcing a mixture of graphite and binder through a die to create specific shapes and sizes.
Extrusion is one of several methods used in graphite machining, alongside compression molding and isostatic pressing.
Each method yields unique grades of graphite suitable for various applications.
What is Extruded Graphite? 7 Key Properties and Applications
1. Production Process
The process begins with a mixture of graphite and binder pitch, which is homogenized in mixers.
The mixture is then forced through a die with a specific cross-sectional profile, a method known as extrusion.
This technique allows for the production of graphite with consistent properties along the length of the extruded material.
This makes it suitable for applications requiring uniform characteristics.
