Extruders(6)

Extrusion is an industrial process that is carried out to deform the plastic. At this stage the plastic is still a raw material so it is in the form of very small granules. The granules are loaded into a loading hopper, after which a screw, rotating inside a cylinder, pushes the granules out through a hole. During this process, the granules are melted by heating inside the cylinder. The hole will have a different shape each time, depending on the desired shape of the extruded product. There are various extrusion techniques, the most important of which are direct extrusion, reverse extrusion, bubble extrusion, co-extrusion and pultrusion. The machines that carry out this process, the extruders, can be of two types. We have single-screw extruders with only one screw inside and then we have twin-screw extruders that consist of two interlocking screws inside the cylinder. The two screws can both rotate in the same direction or in the opposite direction. If with single-screw extruders the raw material used is only in the form of granules, in twin-screw extruders both granules and plastic powders can be used.
