The Plastic Extrusion Machine–Process and Methods
To do this mount a camera above the die and take pictures as the polymer is being extruded. In photo software you should be able to compare the diameter of the die to the diameter of the point of maximum die swell for various process variables. Polymer Extrusion References. 1. Chung, Chan.

Polymer Crystallinity. The polymer structures tend to be very complex because they involve large molecules. In fact the unit cell might only include a portion of a molecular chain. Due to the complexity of the structure, the chain disorder, misalignment, etc. 5-95% of the volume of a …

Extrusion processing can be used to produce components with consistent linear profiles such as pipe, tube, and film. Injection molding is analogous to several of the metal casting processes. Injection molding requires tooling, and the process can produce tight tolerance parts with a quality surface finish in a very labor efficient manner.
