2. Filler (materials) - Wikipedia

   en.wikipedia.org/wiki/Filler_(materials)

   Polymer Foam Beads can have a bulk density as low as 0.011 g/cc and range in size from 45 microns to over 8 mm. Common drawbacks to using Polymer Foam Beads in formulated systems include static, temperature, and chemical resistance limitations and difficulty achieving a homogenous blend within a formulated system due to their extremely low bulk ...

3. Spinning (polymers) - Wikipedia

   en.wikipedia.org/wiki/Spinning_(polymers)

   Wet spinning is the oldest of the five processes. The polymer is dissolved in a spinning solvent where it is extruded out through a spinneret submerged in a coagulation bath composed of nonsolvents. The coagulation bath causes the polymer to precipitate in fiber form. Acrylic, rayon, aramid, modacrylic, and spandex are produced via this process ...

4. Extrusion - Wikipedia

   en.wikipedia.org/wiki/Extrusion

   Mixing elements or convey elements are used in various formations. Extrusion is common in the application of adding colorant to molten plastic thus creating specific custom color. Extrusion is also a process used in fused filament deposition 3D printers, whereby the extruder is often composed of a geared motor pushing plastic filament through a ...

5. Rule based analysis of extrusion process - Wikipedia

   en.wikipedia.org/wiki/Rule_based_analysis_of...

   In direct extrusion the billet is pushed through the die with ram pressure, whereas in indirect extrusion a die moves relative to the container. Rule based analysis of extrusion process would help to determine a set of rules essential for consideration while designing a product, or even during cost estimation of a product.

6. Blow molding - Wikipedia

   en.wikipedia.org/wiki/Blow_molding

   In extrusion blow molding, plastic is melted and extruded into a hollow tube forming a tube like piece of plastic with a hole in one end for compressed gas - known as a parison. The parison is captured by closing it into a cooled metal mold. Air is blown into the parison, inflating it into the shape of the hollow bottle, container, or part ...

7. Polycarbonate - Wikipedia

   extrusion into tubes, rods and other profiles including multiwall; extrusion with cylinders into sheets (0.5–20 mm (0.020–0.787 in)) and films (below 1 mm (0.039 in)), which can be used directly or manufactured into other shapes using thermoforming or secondary fabrication techniques, such as bending, drilling, or routing. Due to its ...
