Aluminium International Today - Essential Temperature Measurement in Aluminium Extrusion
The aluminium extrusion industry is growing rapidly, and world market forecasts show this is set to continue. Extrusions offer lightweight properties, excellent thermal and electrical conductivity, along with strength and corrosion resistance, making them suitable for a wide range of applications, particularly in the automotive industry where fuel efficiency is crucial. Due to their high malleability, aluminium can be formed into different shapes without spending excessive energy, therefore increasing their demand for industrial applications. They are also increasingly used in the construction of green buildings, a major factor driving market growth. 

However, the process of extruding high-quality profiles is not without its challenges. Understanding temperature and controlling press speed and quench rates during the extrusion process are critical to producing products that have the required quality and performance properties. The extrusion press exit temperature, for example, affects the dimensional properties and surface finish of the final product. Should the temperature be too high, the surface finish may suffer imperfections that, apart from being unattractive, can potentially lead to cracks.
