The extrusion process initiates orientation of the chains in the extrusion direction (Fig. 1 left). Drawing or pulling on the extruded monofilament further orients the polymer chains in the machine ...

Scientists at Oak Ridge National Laboratory have developed a vacuum-assisted extrusion method that reduces internal porosity—by up to 75%—in large-scale 3D-printed polymer parts.

Polymer degradation has an immediate impact on the final plastic product and its properties. In the plastic extrusion process, increased temperatures, as a result of the melt processing, in ...

Extrusion is a process used for the creation of fixed cross-sectional profiles. Materials, such as plastic or thermoplastic, are pressed through a die of desired shape and cross-section. Plastic ...

Hot melt extrusion (HME) formulation development depends heavily on choosing the appropriate polymers. This article reviews HME process parameters and highlights three polymers in HME: polyethylene ...

Hot-melt extrusion (HME) is an established process that has been used since the early 1930s, predominately in the plastics manufacturing industry, but also in the food processing industry. Currently, ...

Changing the size of Sonoco's new plastic can is easily achieved by altering the height of the container, allowing consumer packaged goods companies to adjust the amount of product in each container.

In 2024, roughly 54% of new extrusion machine installations throughout Europe are designed to process biodegradable or recycled polymers, highlighting the movement toward a circular economy.
