Thermal treatment of the extrusion moulding material or of preformed parts or layers, e.g. by heating or cooling

Introduced: January 2019

Full Title

Full titles differ between systems:

IPC:

Extrusion moulding, i.e. expressing the moulding material through a die or nozzle which imparts the desired form; Apparatus therefor > Component parts, details or accessories; Auxiliary operations > Thermal treatment of the extrusion moulding material or of preformed parts or layers, e.g. by heating or cooling

CPC:

Extrusion moulding, i.e. expressing the moulding material through a die or nozzle which imparts the desired form; Apparatus therefor (extrusion blow-moulding B29C49/04) > Component parts, details or accessories; Auxiliary operations > Thermal treatment of the extrusion moulding material or of preformed parts or layers, e.g. by heating or cooling

IPC and CPC are identically structured here. All 5 subcodes exist in both systems.

IPC defines codes here since 2019.
