Use correct temperature profile.
Use less back pressure.
Use easy flow or lubricated material.

I really am not prepared to write a novel here for free when some simple homework on you part would give you enough knowledge to at least ask reasonable questions.

Increase feed zone (and maybe the rest) temperatures. Acrylic always "squeals" when feeding, but unless your machines have torque limits you can easily shear the screw or the check ring assembly off. Nasty. Much work and $$$!
And as Pat suggested, get yourself the manufacturer's processing guide - they are free!
