The word ‘extrusion’ implies a pushing out action. In terms of plastic extrusion this is the process of heating raw materials and pushing the molten plastic compound through a tool raw plastic to the desired shape. Water is then used in a cooling process to ensure the plastic extrusion retains the correct shape. We have many different tools with many different shapes that can be used to manufacture a large range of extruded plastic profiles. There are many different types of plastic profile including plastic trim which is often used for edging purposes.
