PAN Precursor Lab Scale Lines

MAE supplies Complete Lab Scale Turnkey solutions for the production of PAN Precursor 1K tow. Using proven technology by Astris Carbon paired with MAE’s long term industrial experience on PAN precursor processing, we can offer Polymerization and Spinning Packages designed for R&D purposes but already embedding state-of-the- art  PAN know-how.


Solution Spinning Optimized Laboratory Versatile Equipment for chemical fibres spinning

MAE’s industrial experience applied to lab scale

The new laboratory line exploits MAE’s long experience in the design and manufacture of equipment and complete industrial and pilot plants for fibre production by solution spinning.
Such experience allows combining in the same lab line the very strong construction typical of the industrial lines with the great flexibility in changing process condition and component set up required by the research and development work.

Continuous production

Continuous production is possible thanks to a spinning pump; this feature allows R&D teams to work all day long to produce one tow of fibre to be tested and to verify its mechanical properties.
Thanks to a dissolution tank, big enough to feed the spinning line continuously, it is possible to run the lab line for 8 – 10 hours, without any dead times connected to the loading of piston spinning cylinders.
An optional additional dope dissolution tank could extend the working time without stopping the production.

Piston spinning is anyway available for dedicated or special end-uses.

Modularity, Versatility, Flexibility

We offer and develop complete continuous spinning lab lines (as well as pilot lines), which can be customized thanks to a modular concept: this set-up makes it possible to move and reposition our modular units in a few hours, as they are easily movable.
Flexible configuration is the key for lab scale test. We can supply two different arms for Wet Spinning and Air Gap (Dry Jet) Wet Spinning: this feature makes our line ideal for matching R&D purposes, which require the test of different configuration variables each time.
