We have a Filabot EX2 extruder with a meager 12 L/D ratio. We want to make some 2.85 nylon filaments with some special fillers. So far, I've only had experience with the EX2, and have a few questions:

My understanding and brief experience is that the EX2 can't provide enough shear to adequately melt/mix the polymer to produce a consistent filament. Are there ways to mitigate this issue, such as slowing down the extrusion?

Anyone have suggestions for extruders that would be capable of extruding nylon with high filler content, or at least help me understand what I should look for?

What about suggestions for vendors that could potentially make this filament for us if we send them the material?

thanks
