They compare quite favorably to the Paulson training videos we watch in the actual industry, though those were more in depth, many hours longer, and came with interspersed quizzes that really helped my understanding. Both are infinitely superior to almost any classroom. Topics this video didn't cover include friction/slippage along the barrel wall, circulation in the melt between each screw flight, the thrust bearing at the back end of the screw that takes the load from pushing the plastic forward, two-stage screws that drop the pressure in the middle to let gases be removed from the melt, how the plastic cools differently at the edges and center if it is crystalline/amorphous, and more.
