The photo shows a cross section of two pipes:
1.) on the RIGHT side best quality pipe of density 24 kg/m3 from a potential Customer producing it more than 20 years.
2.) on the LEFT similar pipe of same density 24 kg/m3 produced on ALEMO equipment after 1.5 h of parameters optimisation, with exactly same raw materials.
The cell structure of ALEMO pipe is more regular and much smaller. The material has lower lambda and higher resiliency and other phisical properties.
Thanks to superior twin-screw design and process control equipment/software, the process stability of ALEMO extruders is extraordinary!
