An extrusion cylinder has a cylinder body for accommodating an extruder worm and is characterized in that an outer wall of the cylinder body has at least one depression which can be covered and which in the covered state is suitable for conducting a cooling or heating medium for controlling the temperature of the cylinder body.
Claims15
An extrusion cylinder (100) with a cylinder body (110) for accommodating an extruder worm, wherein
- an outer wall (115) of the cylinder body (110) has at least one depression (120) which can be covered and which in the covered state is suitable for conducting a cooling or heating medium for controlling the temperature of the cylinder body (110), wherein
- the at least one depression (120) has straight segments (122), which run parallel to a longitudinal axis of the cylinder body (110), and curved segments (124), which produce a connection between two ends, lying adjacent, of precisely two straight segments (122);
- and
- through the connection of straight segments (122) and curved segments (124) a flow path without branches is defined,
- furthermore with cover elements (130) which are connected with the outer wall (115) of the cylinder body (110) in such a manner that they cover the at least one depression (120).
