Extrusion

The production process of aluminium extrusion profiles can be controlled completely using non-contact temperature measurement. The quality of the final product can be improved dramatically by temperature control.

The following critical processes of aluminium production can be controlled by IMPAC pyrometers:
 

Process		Conditions		Recommended pyrometers
Billet measurement		After preheating of the billet the temperature is about 400 to 500°C. The surfaces of the billets are unequally oxidized or reworked.		IS 12-Al with  Emissivity enhancer
Aluminium profile (exiting the die)		The pressed aluminium profile exiting the die has temperatures, which range between 500 and 600°C.		IS 12-Al IS 12-Al/S
Aluminium profile  (quenching process)		Continuous measurement of the profile temperature (from ambient temperature upward).		IP 140 / IPE 140         with Emissivity enhancer
Measurement of machine tooling		Temperature measurement of machine parts, e.g. of preheated dies.		IGA 5  IGA 8 plus IGA 15 plus
