Very high temperatures will result in bed fluidization, and you will not achieve polymer extrusion. Keep an eye on the pressure transducer, which needs to be cleaned on a regular basis. ... Be sure to keep track of all of the samples by labeling them and placing all of the samples for different process variables into plastic bags. This was ...

Extrusion. This process can be compared to squeezing toothpaste from a tube. It is a continuous process used to produce both solid and hollow products that have a constant cross-section. E.g. window frames, hose pipe, curtain track, garden trellis. Thermoplastic granules are fed from a hopper by a rotating screw through a heated cylinder.

https://info.5y1.org/plastic-extrusion-process_1_41edcd.html
An extrusion process forms plastic tubes, called parison. Molds are then clamped around these tubes and air is injected, causing the tubes to be blown against the inner walls of the molds forming a bottle. PROBLEM. These parison tubes develop a static charge during the extrusion process.
