Presentation<\/h2>\n

Extrusion is a shaping process widely used in the plastic industry. It is the key process for mechanical recycling. Extrusion consists of gradually heating shredded plastic particles to form a soft, viscous paste later shaped to create new objects.[\/vc_column_text][\/vc_column][vc_column][vc_single_image image=”6043″ img_size=”full” alignment=”center” qode_css_animation=””][\/vc_column][vc_column el_class=”descriptions_machine”][vc_column_text]<\/p>\n

Items Description<\/h2>\n

An extruder is composed of four main elements, which include a motor<\/strong> that rotates and a worm screw<\/strong> inside a sheath<\/strong> heated by resistors<\/strong>.[\/vc_column_text][vc_column_text]<\/p>\n

Process Description<\/h3>\n

Once shredded, washed, and dried, plastic particles are placed in the hopper. They flow progressively into the sheath, heated by the surrounding warm resistors. A worm rotates in the sheath propelling the plastic to its end.<\/p>\n

The plastic is gradually heated by the sheath’s warmth and its friction with the screw. The initially shredded plastic then becomes a homogeneous soft paste. At the end of the sheath, a die allows the molten plastic to flow out.[\/vc_column_text][vc_column_text]<\/p>\n

Case Study<\/h2>\n

Extrusion is rarely known on smaller scales, as the machine requires an initial investment that can be substantial, as well as a certain level of expertise concerning its process. However, it is an essential part of the recycling chain as it allows the shaping of previously developed plastic waste into new objects. Thus, it adds significant value to plastic waste.<\/p>\n

The alternative to extrusion is to melt the plastics in a heated container, like a pan on the gas. The melting temperature cannot be regulated, so plastic tends to burn and emit noxious and polluting fumes.[\/vc_column_text][\/vc_column][vc_column el_class=”informations_techniques”][vc_column_text]<\/p>\n
