The goal for any extruder is to maximize throughput while maintaining quality products. Increased throughput means that each press can produce more products and be more profitable and time efficient. Temperature control is a critical component of the extrusion process. Running the presses based off of temperature control will allow the customer to maximize their press efficiency while also completely eliminating temperature-related quality defects.

Williamson Wavelength Technologies

Aluminum is a non-greybody material that has complex emissivity characteristics that vary with alloy, surface roughness and oxidation, making it a particularly difficult material to measure with ordinary infrared pyrometers. Traditional single-wavelength and ratio temperature sensors are not able to accurately measure aluminum. Williamson’s multi-wavelength pyrometer uses application specific algorithms to compensate for these unique emissivity characteristics of aluminum. These algorithms allow the Williamson multi-wavelength pyrometers to achieve accurate and repeatable temperature measurements at multiple points during the aluminum extrusion process.
